I have a question for you then? I'm using the EP4000, and driving 2 of these drivers in a single (push/pull) sub. When I selected the amp, did so partly because of the power requirements I had, and it matched them, but also of the advice of others. The plate amps cant match the EP4000, but I stand to be corrected.I'll have to recant on the 420W. Not sure where I got that from. The Berhinger full range, continuous, into 8 ohms is the spec that's the best to use. That's 1300W. The question becomes what will it do into 4 ohms continuous and at what distortion rating? Don't know since they don't specify. They specifically do not specify anything full range or continuous at 4 ohms when bridged mono.
I'm not saying the Behringer won't work and might not have a bit more juice - but there's no way to know other than putting it on a bench and measuring it. My suspicion is that if they actually did that and it performed well, they would have specified it.
I don't want to turn this in to a Behringer bashing party. Not meant that way at all. Their EQ products are some of the highest value components out there. Amplifiers just don't tolerate maxing out parts specs as well as other things. When you start to push them hard into low impedences, things get stressed. When everything is built just good enough, stress can push you over the edge and cause failures.
This is the kind of advice that lead me to the Behringers.The plate amp definitely will not have more power than the Behringer EP2500 in bridged mono or even stereo - not even close. I'm amazed nobody else has chimed in on this thread yet, as there are countless EP2500 owners, and this amp has gone through some rigorous testing - check here for actual numbers of the O Audio and Behringer.
To sum it up for you, the O Audio can barely pump out 460 watts into a 4 ohm load whereas the Behringer can produce nearly 2000 watts with a fraction of the distortion of the O Audio.
Get the Behringer. Until something else comes along - which we will all jump on and make it well known - it's the best bang for the buck for DIY subwoofer usage.
No, I did not personally test it.bpape said:I tend to believe what he says if HE personally tested it
The plate amp is meant for subwoofers, so he chose a frequency within the intended range. Why he didn't test lower I'm noty sure, but I doubt any major fluctuations. The Behringer is intended to be a 20-20khz amplifier, so he tested it - along with all the other standard amps - with a standard set of measurements, checking at 20hz, 1000hz, and 20khz. He kept tripping the circuit breaker with a 20hz test on the Behringer, so he couldn't get a good read on how much sustained power it could actually deliver, as he lets a sine wave run for a few minutes before recording the values (nuts in my opinion!). Any more detailed questions than that would have to be addressed to Chuck himself.They only tested the plate amp at 80Hz? Nothing in the 20 and 50Hz columns? No 50Hz for the Behringer?
Is this statement really the case!?That subwoofer has 90.4 db sensitivity which is quite high for a sub. In theory it will produce reference levels of 105db with about 30 watts input,
