Boston Acoustics PRO50SE (Pro50 SE)
Depending on what kind of music you listen to these are either OK or really good.  The tweeters work well for slow, classical, jazzy type of music.  If you want to listen to hard rock, metal you will be disappointed.  I've had these in my car for going on 7 years now and have always been disappointed with the power capability.  As soon as you turn them up they start to distort (did this since I first got them).  I'm finally looking at replacing them.  Tired of listening to them crackle at high volume.<br />
