Hello! I'm looking for suggestions for a suitable power amp for a pair of EV qRX153. The cabinet has to be bi-amped. The low is a 400w 8ohm 15" driver The mid/high has a horn and 10" driver with a passive crossover network: Impedance is 12 ohms. Ideally I'd like a 4 channel amplifier to do this! It will be fed from an EV DC1 which I already have. Opinion on speakers is subjective so I'm not looking for comments on the equipment... Just suitable amplifier suggestions of reasonable quality! Many Thanks! Richie
