Getting the Cleanest-Highs

[kngadrok]

Anyone know Which of these 4x6 have the best SQ, but get very Loud.
I only need Highs out of them.
Right now I have Kappa 462.7 I think they are clean, but not loud enough.
They are getting 70w@4ohms from JLA6450

Are these any better for what I'm looking for?

BA 746
Polk MoMo mmc 460
JBL P-6452

I know there is a big jump in Price going with the BA's.

BA's arent really any louder, they just sound better. Thats one thing to keep in mind with speakers. They higher the price doesnt nessasarily mean they get louder, just sound better. 4X6 have a mechanical disadvantage in their design that give them a handicap when it comes to throw. Your not gonna find 4x6's that get insanly loud. Those kappas you have are gonna be at the upper end of the spectrum in that regard

Im must be blind, for some reason I had it in my head that the BA's were $200 for some reason.
