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"!

Half of communication is listening. You can't listen with your mouth.
