In my research for the biggest bang for the buck on a subwoofer amp, I came across the Behringer EP2500. Here are the details on this amp:

But in a nutshell, it puts out 2,400 Watts into 4 Ohms bridged operation!
450W @ 8Ω Stereo (per channel)*
650W @ 4Ω Stereo (per channel)*
500W @ 8Ω Stereo (per channel)**
750W @ 4Ω Stereo (per channel)**
1200W @ 2Ω Stereo (per channel)**
1300W @ 8Ω Bridged-Mono***
1500W @ 8Ω Bridged-Mono****
2400W @ 4Ω Bridged-Mono****
*20Hz - 20kHz @ 0.1% THD, both channels driven
**1kHz @ 0.1% THD, both channels driven
***20Hz - 20kHz @ 0.1% THD
****1kHz @ 0.1% THD
Frequency Response: 20 Hz - 20 kHz, +0/-1dB(10dB below rated output power), 5 Hz - 50 kHz(at -3dB points)
And I found that through independent testing, the actual output were close. Check it out here:

This, as it turns out, is not common with a lot of amps. And you can't beat the price: I've seen it as low as $270 and up to $375 shipped!
I see these Pros: Huge Power/Headroom, Price, Sturdy
I see these Cons: No Sub adjustments such as Phase, Cross-over (but most AV Receivers actually can control this), etc., Not as attractive as other amps, Rear connections are Pro Audio type (XLR) 1/4" TRS inputs) which require purchase of connectors, has a fan (but so does my PS3).
So as a Sub Amp? What do you think? What am I missing?
