i had them before. they are in my friend's ride. they sound nice and clean. the tweets aren't harsh and the mid response is very nice. for the money they are excellent speakers.
anything else you want to know?
i gave them 150wrms each and they worked out great.
im considering the xr's...i hear them today powered by a JL amp, but i have a kicker amp, will they sound not as good in my car, or will the amps not make too much of a difference...
and how do you think they compare tothe POLK MOMO 6500 components
