I thought i had to throw this up here, as the M80's would be replacing an old set of Polk SDA's. Now neither speaker will sound like the SDA's persay..plus there 25 years old.
But the 9's are close to the M80's.

Has anybody listened to, or compared these 2 speakers, and what were your thoughts about them????
The only thing i got out of the 9's reviews, is they need alot of GOOD power to make them sound good. But thats about it as there are never to many bad comments about any speaker...LOL
