Hey guys, I was wondering if you could help me out. I've been trying so hard to get a nice tight sound on the bottom end of my mixes....and no matter what I've tried so far it all comes out kinda bland with no real punch. The problem i'm having is seperating the bass and the kick to give them their own space. I monitor through M-Audio SP-5B's wich I suspect is a contributing factor. They have very little bass response below 100hz, and what is there always seems wrong. I added a Polk Audio sub from my home theatre system and it has helped a little, i just have to be careful to set the gain. I always seem to have to compress the mix bus just to hear whats going on on the bottom and then my mixes translate too compressed. If I don't use it I'm really just guessing at whats in there. I was wondering if there is a trick that would help out, maybe realating to the relationship between the sub and the monitors. I've tried using a tone generator sending out a sweeping sine wave with a K2 set up at the mix position. I then matched the sub to the monitors so all the frequencies were reaching the mix position at the same volume +/- 1db. I also adjusted the crossover on the sub at about 100hz (about where I hear the volume drop through the m-audio's.) Is their something else to it? I use M-Audio SP-5B's Polk Audio PW250 250watt 12" Sub M-audio Delta 66 Ashley CL52 Stereo Comp/Limiter .....The more I think about it as I read this, the more I realize what my next purchase should be.........great monitors :lol: Hmmm.....we'll put the budget at..........$1100-$1500........ ....Ive had these SP-5B's for about 3 or 4 years and i know thier faults and their strong points......i know where i can trust them and where I can't......Is there something I can do so I can get a little more milleage out of them while im saving 1500 for some new ones?
