I wish I had room for a rear channel speaker with a bigger woofer. But I don't. And the bass response does suffer on these; I would not say they provide usable response below 100 Hz, in spite of the description's claims, and my AVR agrees.

That said, for the purpose of the rear channel, to fill out the surround experience, these have worked great. No muddiness at all in the mid- and high-range frequencies, and as part of the whole setup, they give all of the ambient cues needed for a good TV and movie watching experience.

I would not use these if I wanted a quadrophonic *music* experience. They aren't up to that task. But that's a fairly niche and rare user scenario, I think. For home theater purposes, these have worked really well for me.
