I'm designing a budget 3-way active system for the living room atm as we've been surviving off a €100 Creative 2.1 satellite system since early this year. The system is mostly made up of odds and ends that I've had sitting around for a while, but the one aspect that I haven't got sorted is the amplifiers.
I need 6 channels in total, with at least 50 clean watts into 4 Ohm per channel for the bass drivers, and a little less than that for the mids and tweeters. I don't want to spend more than around 200€ on amplification (including power supply).
These new-ish Sure Class D boards seem to fit the bill.
However, the datasheet looks very suspect to me. Words like "typical" in front of the measurements, discrepancies between the claimed specs and the graphs, and disclaimers like "subject to change without notice"... Also, although distortion and noise measurements are excellent for a €33 board, the frequency response is pretty wonky (not a problem in itself as the system will be EQ'd with DSP, but... concerning).
Looking at the information that's available, can anyone tell me if buying these would be an unwise decision? Or perhaps someone could recommend some better alternatives?
Help much appreciated
