Hello again RO. Been an eventful and long time since I've been back here. I finally opened my studio, Vibrations Recordings in September of last year with so much incredible support from so many great folks here for the last 17 years or more!.
Recently Kmetal, who has become an incredible mentor and friend, and I, have been running REW programs to fine tune the CR. Room design and treatments along with speaker placement experiments have provided a relatively "flat" room response curve.The last thing needed is to tame a 60Hz bump. and the only viable options I've come across are commercial units costing up to 15k (eek!) or the use of a bass array with DSP to possibly utilize phase offsets to tame the beast.
Through my research the resources I found only seem to address using a bass array in a square room. My CR is a corner design. The rest of the response curve seems pretty good and translation so far of projects seems adequate. Perhaps I'm just naturally compensating for the 60 cycle bump?
Either way The REW results are consistent and I want to do all I can to control it within reason and cost. I'm wondering if anyone here has had any experience with the bass array solutions or have any other suggestions to offer?
I apologize for being so out of touch and hope to follow up with pictures of the digs so wonderfully saved by Rod G. after my humble attempts to do it all myself!

Hi Vibrations, and good to…
Hi Vibrations, and good to see you again!
Your studio sounds really good, and some pics would be great.
Regarding the 60Hz rise in your response curve, what type of monitors are you using? Are they powered or do you have a separate full-range power amp and then crossover networks for splitting high/mid/bass at the speakers?
If you have powered monitors using standard line-level inputs, it's not that difficult to make a passive filter to fit inline with the inputs to deal with a single-frequency anomaly. You may lose a dB or so on level, but that can usually be made up by adjustment of the gain trims on the rear of the monitors. Can you show an example frequency response plot to illustrate the height and width (to get the Q) of the resonance?

Hello Chris and Bos. Thanks…
Hello Chris and Bos. Thanks so much for responding! My web site is vibrationsrecordings.com. Also on FB.
Life doesn't seem to want to slow down much lately though I intend to follow up with pix and sound files. I'll also do my best to post some REW shots.
For now, to provide more details:
1. Speakers are passive: PMC IB1's, Internal crossovers with potential isolation of feeds to all three speakers on each. All connected right now with one amp ea. speaker.
2. Driven by 2 Hypex digital amps Purely amps with no other functions.
3. Orion 32+ interface. No equing possible within it that I'm aware of
4. Studio one 7 DAW. It would be challenging to preset equing mains 2bus for each project, even though my templates could be preset. Seems like it might be a wonky way to approach this?
Thansk guys and I'll be back with pix and sounds soon.
Later!
Hey, nice seeing a post from…
Hey, nice seeing a post from you! Great name for your studio too. I'd love to see pics sometime and of course any mixes. I love hearing what our member are doing!
Sorry I can't help on that bump and wow, 15k, yikes!
Glad you and Kyle are in touch, say hi to him from me. Looking forward to any suggestions others may have.
