I would like behringer to bring out an amp capable off running 2ohms bridged into 2000 watts without even a degree off heat. And only charge 300 for it. LOL never gonna happen

Just got my EP4000 for my two subs, at 4 ohms each are rated at 1000 watts. I use a boost of 6db at 18Hz so even in my small space and moderate volumes will draw a lot of power. The only complaint I have thus far is the fan. I ordered a replacement before even getting the amp, I was well informed of this problem. Still waiting on the balanced miniDSP though. It will allow me to use balanced for the sub from the UMC-1 to the amp. My, the fan that it comes with is loud! I'm used to 80mm computer fans and the three 120mm's in the bottom of my computer case which when set to low make hardly any sound at all and still cool it well. I think the new fan will come today.
The info in the powerpoint presentation about Class D amps was a good read. I take it that even Class D is good enough for subs, just not full range.

I am using a 34 CFM rated fan and am running 2 ohms stereo without any issues. The amp gets hot when running low frequencies but for normal music and films its no probs. I did have a 19 rated CFM fan and it was useless. The stock fan is about 50ish CFM rating which as you know is very loud.

Stick with something between 25 and 35 and you will be fine.

Well, I ordered the 19cfm model from Digikey. I'm hoping it will work given the light duty I will be using it for. If I'd seen what you said before ordering it I would have gotten the higher output one. I'll keep an eye on it and see if it shows any sign of overheating. Wish me luck.

See how you get on. You may be ok as you are running a 4 ohms load.

I think ventilation around the amp is a factor too. I have mine mounted in a rack so they're going to be warmer. If the amp has a little room to breathe the fans shouldn't be everything... I know some people put theirs on shelves.

I remember when you could hear a difference with switching power supplies. I don't know if this is still true.

Dont forget the Behringer amps are designed to be rack mounted, and are designed to run in situations were heat might build up. The EP series were rock solid, I'm sure the new ones will be too.

Totally agree moonfly... just wanted to throw that out there - since they're designed to be rackmounted with the fans as designed..

I think when you reduce the airflow and have it mounted in a hot rack, you COULD have problems.

But... they're also typically used professionally as full range amps........ and I know my sub amps basically sit idle except for LFE booms and junk.

I don't really think heat is a problem for HT use - as long as the rack isn't super hot.
