Very good, but lack bass
Crutchfield Customer Review (What's this?)
I use a mid 70's Marantz 2245 to drive these speakers. The sound is very clear and crisp, especially in the mid and high range. I really enjoy classical music with string instruments on them. They are not to big and fit easily on a book shelf, but weigh about 18 lbs combined. They do need to be separated from the wall to allow for as much bass as possible, due to the back side port.
Pros: Bright, clear, crisp sound. Small size. Price can't be beat for sound quality.
Cons: Need separate bass speaker if you want hard hitting bass. Make sure you amplifier can drive a 4 Ohm speaker
