Why not tri amping with little 5w single ended amps? in 2-Channel Home Audio Posted February 22, 2009 colterphoto1 suggested I give this question a try here: My crazy idea is to use active crossovers to drive 3 stereo 5w amps (like the old Magnavox console amps) into long horn (400 mids) type Cornscalas. So I'm talking a separate channel for each driver. Setting aside the challanges of phase/delay among the drivers, seems like the 15w per channel would be plenty of power to make it work. What about noise? I'm under the impression that noise would not be bad because power is kept at low levels, is that wrong? Any thoughts on this idea appreciated.
