Polk 651.. which one?
 

I'm thinking of getting a pair of Polk 651 speakers for my rear doors. Is there much difference between the 651 and 651s sound wise? I know the "S" means shallow depth but I don't think it will matter. My Blazer is a 2000 4dr 2wd, in case you need to know that.

So which one is the richer sound experience? Price is the same.

I really have never been a fan of shallow depth speakers.. I think there is a difference in sound.
the regular mouth usually handles more power, and can handle a lower frequency..
