The Bronze LCRs will have about 2 dB more output than the Gold Omni SE, but the Omni SE series, as eveident from the higher price, uses better drivers. If you will not be "headbanging" I'd use three InCeiling Gold/8 Omni SEs, and a pair of InWall Silver/4 Surrounds in the ceiling for surround. (All five grills are the same size, too.) I'd recommend two more InCeiling Gold/8 Omni SEs for the back, but due to the proximity to the seating area, they would hotspot too much. Either an InWall Silver/15 PowerSub or InRoom Silver PowerSub with the RackAmp500 will give you solid sub-20Hz bass. That puts you at about $6,000. If you use two InRoom Silver PowerSubs with the 250 watt amp on board, that would put you at $6,800, and the bass would be cleaner and room modes will be smoothed out.
My recommendations of this particular setup favor the best possible fidelity for your application, and give up, as I said, about 2 dB of output. It's a good trade, and with the two subs, you'll still be able to pin people to the back wall.
I won't be on the forum for a few days...traveling. I'm not ignoring you!
