oops, that should have read XLS :b [/edit] added Crest Audio options[/edit] Does anyone have any experience with the new Crown XLS series amps (the new 2U chassis)? Like many people, I suppose, I've been scouring the web looking at different options for bass amplification. I ran across these, and they look promising. The specs all look pretty decent, and it has a good, clean look (something I can't say for many prosound amps) - I wouldn't be ashamed for this one to be seen. I'm wondering about fan noise - didn't see any specs on that, but pics do show that it has two large fans in the rear, and uses a front to rear flow direction. http://www.crownaudio.com/pdf/amps/135738.pdf As far as price, I'm looking at 4 ohm operation at the moment, and here are some of the contenders: Crown XLS402, 400W x 2, $300 from PE, $.375 per watt Carvin DCM1000, 350W x 2, $360 direct, $.514 per watt Carvin DCM1204, 300W x 4, $470 direct, $.392 per watt QSC RMX 850, 300W x 2, $300 online, $.500 per watt QSC PLX 1202, 325 x 2, $600 online, $.923 per watt Crest Audio CPX900, 300 x 2, $350 online, $.583 per watt Crest Audio Vs650, 325 x 2, $580 online, $.892 per watt and some more powerful contenders: QSC PLX 3402, 1100W x 2, $1200 online, $.545 per watt QSC MX3000a, 1200W x 2, $2600 online, $1.08 per watt Crown K2, 800W x 2, $1400 online, $.875 per watt Crest Audio CA12, 1200W x 2, $1700 online, $.708 per watt All of these options will give me between 200 and 400 watts per sub... most 300 to 350 (K2 is pulling up the rear here). Ironically, the Crown XLS402 is one of the cheapest solutions (I'd need four... a pair of the Carvin DCM1204's comes in quite a bit cheaper, with the XLS tied with the RMX850 and PLX3402 for second), although it gives the highest raw power. So... anyone used one? It looks comparable to the RMX or Carvin models as far as specs go, but with pretty nice pricing. Are they noisy (fan and/or sound)? Run hot? Burn up in a week? Leak oil?
