I'm supposed to take delivery from UPS today of a Klipsch V.2-400 computer speaker amp. Its 4x60W + 160W subwoofer (80Hz). I plan on making an active crossover and use it to bi-amp the JBL 3677's. It was $100. Crossover will cost me maybe $20 to make. I think I have an LM 1875 in my little Marshall practice amp. They claim its 15W into 8 ohms.
