Power amp for PA subs

[walterw]

back to the point of the thread, why would a better make of sub cancel worse than a cheaper one when spread apart? that makes zero sense.

i'd guess a polarity error somewhere, but in that case they'd be even worse when center-clustered, and the OP said they sounded good there.

grasping at straws here, but could there have been different cabling used for the split-out setup vs. the center-cluster, and could one of these other cables have been wired backwards?

we've all heard and used split-apart subs in bars and clubs and such, and it's invariably fine. not as good, but fine. people move around, walking into and out of the various lobes of in-phase low end to where it just sounds like "low end" to them.

also, a big ol' mountain of room gain and reflection usually swamps these kinds of details anyway.

Here is what has been bugging me about the whole clustering thing. My old setup used a pair of JBL subs just like the current JRX series. I used 2 of them with one side of a PLX 1602 poweramp,cabs typically 30 feet apart at most gigs. It was barely enough power to get the volume needed,but it worked and the low end was never lacking. I hook up the Yorkvilles with a 3002 bridged mono and it was a real let down.I used new speakon cables too. Clustered they sounded better,but its not always possible to do that at clubs around here where there is little to no stage area. I did see a setup last weekend where 2 CV earthquakes were on stage right with one facing foward,and the other right behind it facing backwards. It sounded really good. So i'm looking for sub that dont need 3000 watts each. 2 sound guys recommended either the CV Jr. earthquakes,or the B52. I'm open to ideas here. Thanks for all the input.

What about the Yamaha PS-series for bass duty? Anyone tried out one of them?
