For all the bother, you're probably better off looking at a pair of ATC active 50's or 100's. They're triamped internally and you'll avoid all the hassle of cabling, shelf space, etc. I'll bet that the results will be very similar for less money too.
Tri-amping speakers - Which amps
I am seriously looking at running a tri-amped system with an active crossover and 6 channels of amplification (the speakers will not use passive crossovers). The speaker designer suggested 100-200 watts for the woofers.
With that in mind an obvious choice would be a 6 channel amp from someone like ATI or others. Another alternative would be to find 3 used stereo amps. Something like the B&K ST140 would seem like a readily available possibility, but that model is fairly old and repairs may be expensive. I guess I am 'testing the waters' with this setup and do not want to spend a fortune on amplification. I can always sell the active crossover and have the passive crossovers hooked up in the speakers, but a 6 channel amp would be hard to find other than new and I don't think the demand would be great to try and sell used. Any sugggestions/
