6x9 speakers with a nice base sound wanted

I personally like polk...they have the crispness you want and enough bass to suffice. Don't be discouraged by the price of them in the stores. Go take a look at the 3 and 4 way speakers Polk offers at your nearest audio shop and if you like them, go to amazon and buy them. Polk 6x9s are $80 on amazon as compared to $150 in the stores.
