get 2 10" 2510 sill very loud and better clarity then the 2515's and the 2510's will be louder then the type X and CVX and sound better the type X isnt very loud
I'm gonna have to disagree. I havent heard a cvx yet but my buddy had a Type X and as far as SQ it sounded amazing so I wouldn't rule out the alpine yet look around a little bit more.
i'd have to say the cvx will get the loudest, definately wont win in sq but they do get loud with decent sq. overall though the dd wins in sql, definately the better of the three. type x shouldn't even be considered. you should also look into the aa havoc.
