why not go on their forum (http://forum.qscaudio.com/forum/) and ask for clarification.
they don't have PR's giving the answers, but an engineer; then you should be able to make a better decision.

Mark, you might also check out the QSC RMX2450 currently at $600 on AMZ(with 15% promo included). It specs out very well down to 2 ohms....aparently this is the amp that Behringer copied on their EP4000 at around $300-400USD.

All those in favour of Mark buying a Pro Amp say "Chowdah"!

BTW, connectivity is an issue on some pro amps and should be considered too.

Look at the Behringer EP2500 into a 2 ohm load!

Yes, if you can believe those specs posted at AVS (and I see no reason NOT to), those amps seem capable.

Chowdah.

The guy that does those amp measurements on AVS I think was a Crown technician at one point?

The methodology seemed sound. I thought the data was pretty compelling, and I appreciated the referral. I can't handle spending time on AVS, so it's great when someone actually identifies the relevant stuff that I can cherry-pick. That Behringer sure seems like a good value and a solid performer.

Great looking specs but wasn't there some sort of issue with those Behringer amps a few years ago?

I don't remember if that is one of them. That model number is different than what they are currently selling today. We (myself included) like to bash Behringer because of their reverse engineering but I can't deny they put out some unbelievable value products.

Their highly touted Behringer 2030 speakers are said to be a ripoff of some Mackie monitors.

Not the EP4000/2500. It was the smallest amp in that series that had some issues in the mid range.
