[QUOTE="Bennett Prescott, post: 31626, member: 4"] Re: This one for all the smart, acoustics of sound/math guys. Maybe you guys shouldn't have gone and blown up an amp right after I tuned it the last time ;) When I went in (last year?) the biggest problems were running out of PEQ on the DRPA, half the subs had different drivers from the other half (and the DRPA has linked LF EQ), and half the subs were being driven out of polarity from the other half. Once I solved... err... one of those problems I found the rig got up and went pretty well, but of course I spent about two hours in the place and I have never mixed there so I don't have a good idea of what it takes. I started from scratch and built up my own XO and EQ based on a secret formula I keep in my head. I did [i]not[/i] tune it at FOH, I tuned it for the center of the audience area. As FOH is up against a boundary that may be half the problem. Why not put the subs against one wall? Get rid of one boundary, at least. You could stack them and maybe make it better... maybe make it worse. Hard to say in those sorts of confines. I have been trying to get those two Eminence drivers changed out so the LF is all JBL, but as people rarely harass me about the system in the Saint I admit I have not been terribly on top of it. It could be worse, you could be in the Wonder Bar! Attached find my settings in rigorously defined Excel format. Or maybe just a photo of what I scribbled on a piece of note paper. If the amp that replaced the blown up amp doesn't have identical sensitivity it will be wrong... I should have bit the bullet and re-tuned that rig with constant gain. Sorry! [/QUOTE]
