Looking to upgrade tower speakers. Just have 2 of the factory 6" Roswell tower speakers right now. I did have a 10" subwoofer installed last year and upgraded to a Kicker DX 600.5 amp. Looking to add a couple tower speakers so we can hear the tunes when wakeboarding. I was looking at the Rev 8's or the Rockford Fosgate speakers. Any suggestions? I'm not the typical stereo guru so I'm looking for some help here. Any input would be helpful. Willing to spend $1500 - $2k for something that sounds great, but don't have to be the loudest on the lake.
