sorry but the eclipse stuff @ circuit city is definately NOT the best sounding speaker they carry or have on display. I am the head installer in my roadshop and have been there for a few years, so if you haven't installed a set of eclipse 6.5's in a vehicle and then compared them to polk audio 6.5's then you don't know what you are talking about.

The speakers that CC carries from eclipse are the bottom of the line eclipse and severely lack any sort of midbass and sound like absolute trash in a car if not amped and/or backed up by some sort of setup providing bass/midbass

this is obviously just my opinion, but I know a ton of other people agree when it comes to CC's eclipse line and the Polk DB's we carry.
