The Response 2.5 works great with our M-60s, but as I recall some customers could run them (60 watts) out of power, although they were in a large room. 6-8 watts just won't be enough.
Set amps ?
How do these 2-6 watt amps work ? Can they drive proac response 2.5 speakers . What is so great about them?. What makes them tick ?
