very well build. the lows, mids, and highs are there and are in sync with eachother.

none that i have found. i will finish the reviw after i have broken them in and really tested them.

I just put these speakers in my car yesterday,and they sound incredible. i'm slowly breaking them in and already sound great. I had kicker ks65 in my car and these speakers sound so much better than them. i highly reccomend them to everyone. i love home theater and car audio and know quite a bit about how speakers should sound and these out of the box made me smile for a long time. i out 4 of them in my altima and was shocked at how well the bass, mid, and tweeter went together. their very smooth. the bass isn't overwhelming at all. the woofers produce very clean and deep lows. all in all i think that kenwood did an outstanding job on making a 3 way car speaker sound so flauless. fleetwood mac's: greatest hits cd sound very,very good on them. and cat stevens: tea for the tillerman is so clean and clear. i heard things in so many songs that i never heard be for and that simply caught my attention and amazes me. i hope this review was helpfull to all the people interesed in these speakers.
