The crossover frequency setting on the Onkyo is only concerned with whether or not you're using a subwoofer. If you've got no sub, set the Subwoofer Off and don't worry about it.

If you've got a separate subwoofer, I'd set its crossover to 100Hz to start and see if you can balance it out using the sub's volume control. Your Sony speakers claim frequency response down to 50Hz, but I'd expect a dedicated sub to do a better job below 100Hz. That will also unburden the Sony 8", which may tighten the low end up (in a good way).

If you're asking about the crossover frequency between the Sony's tweeter / midrange / and woofer, it's not really relevant.

I hope that helps to clear things up.

Yes, I was actually wondering about the crossovers between the tweeter/midrange/woofer.
Figured there was a way to look in the measurements and pick them out.
I believe I seen an image for 3-way speaker somewhere where an arrow
pointed to a spectrum, and something else, and labeled the arrows "crossover".
Not sure where, or what I saw....it's just in my memory for some reason.

No sub for this, just the two bookshelf speakers.
Thanks for the response.

Here is an analysis,
Red is KRK RP5's with a KRK RP10S sub..85dB ref. level
Blue is the Sony 3-way Bookshelf. 80dB ref. level
I offset the levels so they could be offset a little.
I still need to place the Sony speakers in an optimal position,
which I will get too.

I currently have an issue(narrowed down) with my ECM8000, 60hz hum and harmonics,
as well as the Emu 1820M adding DC offset(enabled highpass filter in REW).
Mostly goes away when I hook up my Radio Shack SPL meter,
but the Emu is still causing some low frequency
noises that mess up my waterfall graph.
I will be getting the minidsp usb measurement mic soon, or something.

Are you measuring these speakers in a treated environment? Under good acoustic conditions, obviously, the KRK's will measure "flatter", as they are designed for studio near-field reference; while the Sony's are - I'm assuming by the way you described them as being "bookshelf" - showing dramatic skewing in several areas of the frequency range... I would call that -53 dip at around 100Hz to be a serious attenuation, and your upper range is sloping off pretty seriously above 3k or so... but, this is heavily dependent upon your environment's acoustic signature as well...

Which weight scale did you use to do your measuring?

Is the blue curve showing the Sony bookshelf speakers working in conjunction with the RP10S sub? It's hard to imagine the bookshelf units on their own being only 5dB down at 25Hz, unless your room is playing tricks.

There look to be some pretty serious things happening around 100Hz, as Donny says, although I make the dips only about 23dB below the 80dB ref level.

ADAT optical outputs like those on the Emu and Toslink optical inputs on a stereo device are usually not compatible protocols, but there's a way to set the Emu ADAT output to 2-channel S/PDIF @ 48kHz, is that right?

Unless you intend to tri-amp the Sonys, I'm still not sure what the benefit of knowing the crossover frequencies would be. If a speaker manufacturer shows a freq. response graph (with or without the crossover points indicated) it was done in an anechoic chamber, so it wouldn't have any of the variables you're trying to sort out.

The 60-cycle hum is one thing, which is usually a cabling, or an electrical grounding problem.

The performance of the Sony speakers is another. I also find it hard to believe they're doing as poorly above 3kHz and so well below 80Hz as graphed. That is quite a null at 100Hz. So I'm also questioning the room treatment, the RTA mic position, and the speaker location, and how they're affecting the outcome.

Are the Sonys completely sealed, or ported out the back?
And can you go into more detail about what all changes when you enable / disable the high-pass?

Sorry for the delay..been busy. Room dimensions. Finished basement(concrete, insulation,drywall)
L 22' W 13' H 7'10". Will be putting up a video soon. Pics below. Coming video will show full layout.
I have mainly been doing video editing lately. Some mixing, some mastering.
The original reason behind this was because I was getting that hole from 100-200Hz.
So I was interested in testing the crossovers without opening, somehow.
Something to that effect.

So, did some test, confirm there is an issue with the ECM8000, and maybe something with the
Radioshack SPL meter with regards to measuring. Just happened recently. Never had problems.
Sort of bummed out, because I have not done many measurements with the ECM8000, except
for when I first treated my room. I just recently started doing some more stuff to the room.
I have had the mic since 2007 however.
Below are the issues. SPL in REW was calibrated at 8odB, so calibrated.
ECM8000 at necessary gain(black) and when I touch the mic on the mic boom, not the actual
body. Touching the body does nothing, however, when touching anywhere along the boom of the mic,
I get what you see in RED.

Now with the Radio Shack SPL plugged in, set to 80dB on dial, of course C-Weighted selected, with no
mic .cal file loaded. Still a little something going on.

Now, with an AKG Perception 200, not much low frequency issues as with the other two.

About the room. Some of you have possibly seen my build on youtube.
Floor to cieling corner super chucks with Roxul SafeNsound. 32inch face.

7in thick at top, tapered out to about 10in at the bottom, front wall build.

Back wall: This box belonged to previous owners. It was in the wash room. It had their
washer and drying on it. I turned it into a wannabe poor mans bass trap. Did not put much effort
as you can see. The blue stuff is closed cell foam underlayment that goes under carpet, about 1/4in
thick. The box is prety big. Of course I covered it with fabric. Sits against back wall with underlayment
facing into room. Back side, top, and sides are 1"thick particle board. You can also see a little
superchunk of some white fluffy in the corner, floor to cieling. On top sits a ghetto blaster system,
with switchable speaker sets.

This is a pic before I got the Sony bookshelf and the reciever.
I built a bridge for the monitors out of 2x12.
Side panels are 2 1/2" thick, 54in long, 34in wide. Same as two cieling clouds.
Other little panel on the ground is Roxul. There are a couple of those in there as well.
String on ceiling is for center of mix position.
Left is music production computer, right red computer is video editing beast.
Little monitors are Edirol MA-7A active powered wannabe mix cubes, I got for $8 at a second hand store. You can see the ceiling comes down
9" on left side making it lower, that is heater duct in there.

So, I will be getting a minidsp usb measurement mic here in a bit. Hopefully with will eliviate any issues
I am having with the Emu1820M ECM8000 combo. It used to work fine.

Doing some experimenting with the SPL as measuring device for now.
You they have to be on their sides, to get rid of the big dip around 100hz.
Still have to do some more tweaking. RTA while moving SPL meter, or speakers.
Going to try woofers in,tweeters out. Going to have to bring the green screen back some.
Those are MRE boxes, only temporary. I am in the military, US Army Infantry 16 years.
Photo taken with phone, radio shack spl meter far right on tripod.
Due to placement, going to have to sit back further when listening to those.
They are just another reference.
Due to noise floor with the SPL, and some other issue, waterfall is pointless, because
it trails off infinitely at same level. Today, the SPL had an issue around 37hz. High peak.
Only checking lowend. 75dB ref.

"Some of you have possibly seen my build on youtube."

Right. Don't flatter yourself.

There's a lingering 40hz, You might want to adjust the front wall so there is an air cavity, and use something like 4-6" roxoul. That might help with the sub low. It might help to make that foam area at the top right when facing the mixing desk into a bass trap configuration.

That is only when using the Radioshack spl meter today. Normally it does not have that spike.
You can see it in the mic comparison above, at 37Hz, the largest peak.
This is just with the SPL plugged into the Emu1820M, no sound being played.
As I move the dial to a higher SPL, the peak goes down.

I have considered making a gap, because the wall can be pulled out away from
the other wall. Not following what you are referring to as far as the upper right area.

His comment lacked the professionalism and credibility you speak of.
Thanks for the opportunity to allow me to explain my thought process here.
"Discussion, disagreement, and debate are welcome."
I have no feelings and deal with far worse internet jabs and sly comments everyday.
I said "possibly" have seen my build on youtube, not "I know you are all eager to watch my build."
"watch in amazement as the next guy builds the next DIY studio in his basement."
I see what you did there. Thats cool, but I see nothing wrong with doing it yourself.
That tone seems to me as an implication that maybe a DIY studio, that uses some
of the same treatment/building principles as Pro studios, are looked down on. You know,
"just another DIY guy, look at that guy, with his DIY studio." I speak sarcasm well.
Quite possibly, that was not your impulsion, but that is how it's percieved.
That is reality.

In another thread, this same "regular" told the guy who gets "electrocuted",
"Polarity doesn't matter with AC 110...it goes in and it comes out.

Check the extension cord. And then ask your Dad if he knows."
http://recording.org/threads/why-does-my-studio-setup-keep-electricuting-me.59010/
REALLY?
All because he thinks that guys post, is a troll post.
"Personally....I think the poster AND the question are a setup...so there is no right answer."
The original poster of the thread even addressed it in his response, and was displeased
with his demeanor and approach.
I do commend Brien for his ever watchful eye and ability to spot possible
fake posts and trolls. However, to respond in such manner when it could be legit, is impetuous.

Why are we even bringing this up? He addressed me in such manner,
I handled it accordingly and made my own little joke. No harm done.
So, can he not handle the same treatment? Dish it out, yet cant recieve? I am sure he is a cool guy. I am sure it does not bother him.
He will be fine, he's a big boy.
I figured he was trolling, that is why I said "I am the number one troll."
I am not a troll, but if you attempt to troll, I will most likely troll you harder.
I am not angry, and found it amusing. Sarcasm is my second language.
I responded with a sarcastic comment.
That is why I said "moving on". I know he was being sarcastic.
I do not feel like he was attacking me, or hurt. It's all good.
I could hug him right now and shake hands, and make a toast.
Then he could teach me his ways of studio design. I know for a fact,
Brien is far more knowledgable and could find a million things
wrong with my studio layout/build. I welcome it. I would be his apprentice.
From what I know, he is a freaking genius and has been doing this for as long
as I have been born. I am 35.
Again, no harm done.

With regards to my ECM8000, I posted a graph above showing what happens
when I touch the mic boom. Not only do we have the 60Hz, harmonics and more, but
it boosts all level up. This only happens with the ECM8000.
Is this normal when touching the mic boom end? Don't remember.
Black line is just with it plugged in and gain necessary for measurement of 85dB.
Red is when I touch mic boom part, not body.

That could be a bad mic, bad cable or bad power grounding scheme. It's a cheap mic, maybe buy another? Worst case you have two working reference mics, a stereo pair!

You can probably figure out crossover frequencies by covering one tweeter or midrange driver at a time and running some sweeps.

Is there a rationale behind orienting those big speakers horizontally?

To be honest, when I saw those photos my reaction was, ugh, not another challenged acoustic space. Sure, that comment above may have seemed blunt, but it comes from a source I've seen provide good information about acoustics. There's more to creating a good acoustic space than using "some of the same treatment/building principles as Pro studios".

I'm left with the impression you are working with mismatched and possibly incompatible test tools, and seeing conclusions that are not there. Before you do anything else. Take your speakers and your test equipment outside, somewhere quiet. Run your test again and see how perfectly flat your responses are. Look at the results and draw some conclusions. Without room nodes, resonances and obstructions, you will see something that reflects the performance of the speakers and the test mic, which is a very popular one for this kind of job.

Your pictures indicate a mess of a room with seemingly random problem solving devices all over the place. I wonder if you have introduced so many different products that your room response is wrecked. Could you have used a product to solve a perceived issue, and accidentally created another that another product was used to 'cure', which then caused something else? My own experience was on similar lines in my first studios, a reactive process made worse by me learning as I went along. In my case, when we decided to redecorate, we removed everything, and once painted, did the tests and disovered some of the room issues didn't really exist, once our knowledge gained over a couple of years was used from scratch.

For what it's worth, Sony hi-if speakers always had a unique sound. Amazingly different to British ones at the time. In the 80s and 90s, the biggest improvement in a home sound system was to replace the Sony speakers with British ones, and totally change the sound. The Sony's were NOT bad speakers, but tuned for Japanese tastes. I bet had anyone tested them using today's technology the visual result would have been a real mess!

Looking at that mic trace, what was the test noise source? Or was that simply what the mic was really generating in free space, no test signal? If your test mic hums, throw away every result it's produced, it MUST be flat in silence or it's crazy to use it!

Except we don't know that about you, as we don't know you well enough yet. Forums are communities, and like any community, there will different personalities. The difference is, that over time, people get to know one another here, and we get used to certain things about their personalities. We haven't had a chance to do that with you yet.

You came in pretty hard and fast, loading lots of pictures and mentioning your DIY vids on you-tube, so instead of knocking, you kinda just kicked in the door here, and expected to be accepted right away. Generally, a simple introduction is in order, common courtesy, before you start posting long posts filled with 20+ pictures. Whether you realize it or not, your post did come off as "bragging". And, we also like to make sure that accurate information is provided here on RO. We have experts here in many facets of audio. But we don't know your education, or your experience, or level of expertise.

Just take it easy... let us get to know you a little bit first.

I think you should check the extension cord. And then ask your Dad if he knows.

I think it's more the seeing (and doing) and less the tools. I have that mic, and his SPL meter looks like it might be the same as mine. REW is perfectly adequate software. But, like you indicate, if you don't know what you're looking at you're going to end up with some skewed ideas.

paulears, post: 437112, member: 47782 wrote: Looking at that mic trace, what was the test noise source?

REW doesn't use noise for measurement, it uses sine wave sweeps. It does use pink noise for level calibration.

Yeah, just ordered the UMIK-1 USB mic through Madison Speaker Components from Amazon. Seemed
from the shipping time quoted, it would come from their location, not Hong Kong.
The speakers on their sides for that specific reason, running sweeps one inch from cones.
This was so all drivers are at same height for ease of measurements. Also was experimenting.
I am familiar with why placing them on their sides is not a good idea.

So, once the mic comes in, will do some more testing. Will be opening up those Sony speakers, and testing

Maybe as opposed to being a smart-arse, you should have more respect for the members who give their time and knowledge to RO, a learning based forum.

After all, thats why you are here, is it not?..or is your purpose here just to insult and incite, which will have you removed from the site before you can blink an eye.

My advice to you is if you want people to take you seriously, and by any way help you at all, show some respect.

If not, find another site to ply your crap on, members here who give their time and knowledge don't have time for time wasters or trouble makers.

May I suggest you go back to facebook instead of RO if you want to insult members on this forum.

Where is everyone's comprehension?
Have you not read my post in this thread?

Why are my posts being quoted out of context? They are in response to someone who made a corny comment. NOT someone who added any value, or professionalism, to this thread.
If Brien wants to troll my post, thats his problem. Don't be angry with me for putting him in his place if he needs it.

He has not.
Read this thread in it's entirety.
All my posts, except in response to his trollish comments, were legit and professional.
If he can dish he it, he should be able to take it without everyone running to his aid. He is playing all of you, because he knows his longstanding relationship, that he has had here, will make me out to seem like the bad guy.
In the end he may get what he's after, which is most likely my removal from this site. I know that is his aim, and he is using his seniority to accomplish that. How is that ethical?

So being here longer allows you to post what you want and attempt to bully others? I am being professional with everyone. However, Brien is the one you should be questioning.

Again, all my posts, except in RESPONSE to him, are on par and on subject. I will ignore his posts from this moment forward I guess.

Firstly, I have read the post in its entirety.

Secondly, No-one is running to anyone elses' aid.

Thirdly, this is not Afganistan nor Iraq where you QUOTE "kick in doors for a living" so you can leave the attitude at the door.

This is RO where people have a mutual respect for each other and their areas of expertise, where knowledge and experience is freely given to those who come onto the site to search for answers to all things to do with audio and recording. Its the best of its kind on the web, with the best people in the field.

If there is anyone here qualified to give you the right advice it is Brien. Maybe if you didn't come charging in with your gung ho attitude you may have received a different response. I know thats the impression I received when I read your post, and yes, I read the thread from start to finish...as a moderator thats what I do.

I think if anyone has escalated this and blown things out of proportion its you. Get over it. He made one comment, you went on and on about trolling, post after post.

Let it go. RO is a better place than this. If you didn't charge in like a bull at a gate you may have just realised this and people would be all to happy to help you, instead of getting your webbing in a knot. ;)

Many people don't give enough info with regards to their layout, and situation when posting. I figured I would post as much info and pictures showing my setup as possible. I fail to see how that has ruffled anyones feathers. Wouldn't you want as much info as possible?

My pictures were in response to Donny's question as to if I was "measuring in a treated environment."

I was only attempting to give as much info as possible.
I only continued to talk about trolling, if questioned about my motives and responses. Giving my defense.
I am calm in all this, not some maniac sweating over a keyboard thinking."I will show them".

I type fast, and my posts can be long.

Never meant to come off as bragging, or as a douche. However the KRK's and Sony bookshelf aren't much for bragging rights.

I ordered a new measurement mic, so plan on taking some close measurements to find the crossovers, and best spot in room. They are only for additional reference.

So how about your space and my comments, especially as I've not upset you. Are you absolutely sure the space is not an acoustic train wreck and this is what your problem is?

I really don't understand why you want to investigate these speakers so much? They're oldish hi-if speakers aren't they? They didn't have a remotely flat response when designed, so if you find out the crossover figures, what does it do. To be honest, why don't you simply remove each driver and disconnect them, then test each driver separately? Any Flatish mic will do the job. It'll show you where it starts to tail off, and you will know for certain what each driver is fed with. I really wonder if any attempt to use these speakers will not make you happy.

I've been looking at the system you are using to produce the data. I still believe that what you have could be usable once you test it in isolation to give a baseline for the measurements. The Behringer has been used for years now by all sorts of measuring systems and their natural response doesn't look like yours. Are you certain your room is flat, or at least not spikey in its frequency response?

If it were me I'd start with removing everything there. Including the desk and reassembling your setup so you have a direct line of sight with your speakers at the correct distances. It seems like it's more set up to play video games than mix music with the speaker placement. Extra monitor real estate is awesome but shouldn't be at the expense of basic speaker placement. Doing any mic measurements seems pointless when the speaker angles are all over the place especially the larger Sony ones.

While I am no expert and there are those here that are more schooled on room acoustics that I, the one thing that stands out and caught my eye with your setup was your mix position. As a general rule, speaker placement should be at 38% distance from the wall behind your mix position in regards to the total distance to the back wall.

Your main monitoring speakers should be at ear height and the distance from the centre of each cone to one another should be the same distance from the centre of each cone to each ear, forming an equilateral triangle between each cone and you in the sweet spot, where you are at the third point of said equilateral triangle, points one and two being each speaker cone.

This gives you an optimal listening position. From your images your monitors appear above your ears (although pointing downwards) and the larger speakers on the wooden stands appear to be at a wider angle, therefore you would have differing sweet spots within your current setup as per your images above.

Here is a helpful site that may give you further info, http://arqen.com/acoustics-101/room-setup-speaker-placement/ it also metions Rod Gervais' book Home Recording Studio: Build It Like The Pros which many here can attest to be well worth the read when undertaking studio setup and acoustics, covering many fundamentals to getting it right when it comes to home studios.

Pauls' advice in regards to testing outside the room environment is also valid IMO.

I hope this helps

Not too confident with the overhead speaker placements as well. I'm not really a fan of frequencies bouncing on the ground. Sometimes it adds a sort of reflection when I once tried it.

It is Paul. But that isn't what this knucklehead wants. The original question was answered in the first post by dvdhawk...and the following three posts , ditto.

The crossover of the speakers is hardly an issue. The room in the current treated form would not allow the speaker(s) to bloom in any event. It is indeed a train wreck, the question is becoming a moving target and the poster wants nothing more than the attention so as to continue to establish that he is smarter than the average dumb person, able to leap tall buildings with a running start all the while baffling the on looker with this magic trick.

Carpet on the floor and basically an anechoic chamber as a mixing environment will never produce what the speakers, crap or not, would be able to present. And that was most likely why the post was made in the first place, to define if or not the room was ready, which it is not.

For the next magic trick, watch as this thread continues to degrade and the need for crossover information disappears.

To any of the modes looking on, this thread is in the incorrect category to begin with.

I was getting a big dip between 100 and 200hz. I attempted various microphone heights, and triangular positions,
however, it wasn't going away. I figured maybe something was up with the crossover
network or something. I am not an expert in loudspeakers.
I put it in this section, because I am not seeing a better section.
I figured a guru would know a special setup, distance, and method to determine
crossover from memeasurements alone.
We are dealing with measurements, and the speakers are in a room.
I ended up finding that the ECM8000 was having problems for sure.
I used the SPL meter, for the lowend.
The Sony speakers are 83" apart. Best response is @73" from each speaker.
I got them as a deal for $20 at a second hand store, because my wife loves
thrift shopping.
I used to play Call of Duty competitive. My daughter plays as well, and was
using my area as a Twitch streaming workstation. Chat/internet on far left,
PS4 console on middle, video recording on the right. I also use the 3 monitors.
Not much I can do with the setup, because I have to have 3 monitors.

My monitors on the bridge are angled at 10 degrees. My chair sits high.
They are 55" apart, and I sit about 50" from them or so.
Floor reflections or lack of do not seem to be an issue.
The Sony, which I was figuring had a crossover issue, would be used
for another reference. I would have to lower my seat, and push my chair
back, to be in position. Not a problem.
I was also at the time doing research on the fact that, any height change with
these 3-way, causes alot of change in sound. So figured it was a crossover issue.
I measured each separately, and found it was just that I needed to do more
RTA and adjustments of height, distance, and angles.

But all that is moot, because my ECM8000 is definitely no good.
So, I ordered the UMIK-1.

I figured I would show the whole layout, which leads to other questions
from posters, which morphs the post to flow away from crossover discussion.

I'd bet your dips have nothing whatsoever to do with the crossovers. Silly question, but have you got the same issues if you run pink noise through it and look at the display on one of the phone apps that does ⅓ octave sound display - like Octave RTA that I have on my phone. I wonder if you just have some room node problems. What do the Sony speakers sound like. The Japanese speakers of this era I believe were the cause of the smiley face eq curve.

JUST SO EVERYONE KNOWS.
Tinypic is hacked. Some of my images on other sites are showing up as ads, or nude photos.
However, in the tinypic account, it will show as your original image.
You have to visit the generated link to see the hacked image.
If they show up like that here, not my fault.
Deleting the photos does nothing because the links for the thread are the same.

Where in your original posts here is the link?

Is it in the pics you uploaded here?

They look OK from my end.

I HATE that crap. Now where are those Nude photos and I will verify your accusations!!!

OH...BTW, this aint no HACK site...Chris will not let that kind of thing go on I can assure you. While it may not look like it, I have been here close to 8 years. And not ONCE have I seen a nude photo...NOT ONCE!!

The way I read it Brian is this may be happening on other sites according to the OP...but who knows.

But agreed, Chris would not let or tolerate that here on RO.

Sadly, I suspect it's your computer that is infected, not the hosting site - who usually take great care in preventing these kinds of infection, because they get the hassle. I too see perfectly normal pictures - If you don't then it's your computer that needs a scrub. Usually these things are much easier to get yourself, and probably are taking control of your browser - an extension of the old insert ads virus. So - we're not seeing body stuff.

This is my image on tinypic. It's attached. I screenshot this. If you visit that link in the arrow, you will not see the waterfall graph.
Its not here, I posted in a UMIK-1 mic forum at Mini-dsp site.
I had to report my own post to mods so they can remove the image. I told them the situation.

I messaged tinypic support, but got a message from a robot from photobucket.
No messages here are effected yet.

EDIT: Just visited again, and they fixed it.
It was showing the picture of a chick bent over a couch wearing a thong,
and had a link to a porn site.
I did some research on "tinypic hacked" and others have had issue in the past.
Dang, should have screenshot that...

Here was my message to tinypic support and response.
Just wanted to give a heads up just in case it happened to more images.

My image is now not showing up in my account, but there when I visit link.
Photobucket owns Tinypic

As I mentioned, a search of "tinypic hacked" shows others with the same thing happening to them.

Well - this forum are providing the images from those you linked to at the time, with a server hosted copy of your original. I can't quite see the problem, we seem to be fine - keep moaning at tiny pic, and hopefully they'll fix it. Luckily, we won;t go to your images direct, so from our perspective, we can't see anything which is fine with us.

Yeah, it wasn't an issue with any of these pics here on this forum. It is not an image I attached. It was an image I posted to the hosting site tinypic.com. The images you see in my posts are from tinypic hosting.
I upload to tinypic.com, and use the Insert image and give the URL link to the image.

However my recent images regarding this are actual attachments.

The problem image was an image of a waterfall I posted to a UMIK-1 mic forum with regards to noise-floor.
I quick checked all these images and they were fine.
I was merely giving a warning just in case some of my other images may give a problem through tinypic. I didn't want anyone to think I am linking to bad photos.

I gonna tell you like my last girlfriend told me "it's YOU".

Whatever your issue is, you created it...you do not have to >fix< us...we ain't broken.

LOL, right. Nothing is wrong with Recording.org, it was an issue with tinypic.
Everything is fine here. Again, I was just letting everyone know in case my images
turn into pics of hookers.
