The M5's are good. I have no doubt you'll be happy with them.

That said, you might want to try the M3s with an EP500. My older sub was ok, but didn't blend as well as the 500. Note: The key to a good blend is getting the right crossover and level. If you know the sub is there then its volume is probably too high.

Personally, I'd go for a M3/EP500 or IMO even better a M2/EP500 over a lone M5 setup. Anyone else have thought on this?
