Any feedback on Behringer Europower 2500 power amp? I'm considering one for a sealed box Tumult I'm building. Everybody seems to love the BFD, but haven't heard much on their amps. The specs are couched in an intereting way, as the 2 x 1200 watt output power is only specified at 1 kHz (.1% THD), and the frequency response is specified 10 dB down from full power. So you can't tell how much output this amp will have at low frequencies, where the power supply is taxed the most. So, does this amp have the balls to drive a Tumult?
