They should work with any amplification. Whether you like the results or not is another question.
I used them with Exposure amps and an Exposure electronic x-over designed specifically for the SBL's. I thought the combo worked well in the right room, one with solid walls. I moved away for the SBL's because I moved in to a house with a room that didn't have strong boundary reinforcement. The SBL's are surpassed by many cheaper speakers these days, IMHO.
