Sherbourne 7010/A pre and several Sherbourne Amps. The pre is the same as a Sunfire IV.
They have a 12 channel amp that is bridgeable. You could bridge 6 channels for your front bass and then use 1 channel for each tweeter in the system (11 total, 1 unused). Or, bridge another pair for the center tweeter too. Bass is what is so demanding anyway. There are other sherbourne amps out there as well.
