Has anyone had any experience with these speakers.

I have always heard great things about JBL's professional loudspeakers. A also have a W12GTi sub in my car which has withstood 1100 watts of thrashing for the past 2 years and the sound quality is second to none. I've had Infinity Kappa coaxials before, but i'm just not willing to shell out $300 for four speakers to put in my boat. These appear to be well built, attractive looking, and the price isnt bad. Any thoughts or experiences with these or any JBL coaxials would be appreciated.

Cheers,
