[QUOTE="Phil Graham, post: 33375, member: 430"] Re: Sub Amp? 1 large amp or 2 smaller amps. Loren, Glad to see you built two more :) At Xmax for the driver in this cabinet: (160V_peak/1.414)^2/8 = Any amp that will do 1600W into 8ohms (or 3200 into 4) will work. While bridging amps is no big deal, one box per channel of a PL380 looks good to me, just buy two of them. Or you could buy 4x RMX2450 and bridge them. No need for all the fancy limiter gizmos in the iTech if you're not beating up on them all the time. Forum regular, and all around good guy, Jeff Knorr has some PL380s for sale in the marketplace [URL="http://www.soundforums.net/live/threads/1933-End-of-Season-sale!-Danley-QSC-PL380-FBT-Whirlwind-Sennheiser-and-more!"]here right now[/URL]. Buy two, turn on the clip limiters, set the processing from the spreadsheet and forget worrying about blowing them up. :D~:-D~:grin: [/QUOTE]
