Forgive me if somebody already posted this info. Parts Express has released several new high power yet affordable subwoofer plate amplifiers. The two that really caught my eye are the larger amplifiers. The first is a 540 watt subwoofer plate amplifier for under $300: http://www.partsexpress.com/pe/showd...D=124777&DID=7 The second is a 1024 watt subwoofer plate amplifier for under $400: http://www.partsexpress.com/pe/showd...D=124775&DID=7 Both amplifiers also feature a fully adjustable parametric EQ which can be adjusted from 80 to 18 Hz, +6 to -14.5 dB, with an adjustable Q value of .1 to 1. This is great news for folks who have a room mode that needs taming. It also means that you can set up boost or a rumble filter EXACTLY where you want it. It also features a 24 dB/octave low-pass crossover that is adjustable from 200 to 30 Hz. I am impressed that you can get all of this performance at this price. I will probably never use a pro amplifier again. I can't wait to throw one of the 1000+ versions on my Blueprint 1803.
