I was looking for a decent set of 6.5 components for my trusty 2002 Subaru WRX. The problem with my Subie is very shallow doors. I chose the Polks as the best speakers that would actually fit in my doors. Mostly I listen to classic rock, and the Polks are great for that. They have a balanced, smooth sound that is good for most music. They do produce good (but not great) bass, much more than my doors can handle. The only music I find they can't handle is very mid-bass heavy groups, such as MGMT. On such music the speakers bottom out and end up sounding like crap. This problem can be reduced by drastically altering the EQ, but that has drawbacks, too. These speakers are probably best for most rock, jazz, and even classical. I am not sure they would hold up for hip hop and rap.
