[QUOTE="Helge A. Bentsen, post: 90189, member: 263"] Re: High output subwoofers. I learned that the hard way. I messed up my alignment one day and it sounded like shit. I forgot to check the base delay on one of the subarrays, it was 6ms off. So I measured one side, got it pretty good, but everything collapsed when I turned on the whole system. Took some troubleshooting to figure out what was wrong. This year I used 20 JBL VTX V25 as mains with a xo of 80 hz. I ran out of headroom in the subs first(s28). Nothing wrong with the system regarding sound quality, I'm rather pleased with that, but I'd like to bring in some more subs because I was hitting the limiters pretty hard on them, but I can't use more than 12. Lowering the xo to 60 got me some more headroom but a more un-even subwoofer coverage, so I'm looking for options :) I fully understand if you think this is crazy, because it is. But the customer asked for a solution and he's willing to pay for it. So I thought I'd look into it and give him some options. This thread shows what the challenge is....
