Need New Speakers for Roswell Cans

[yukon2007]

Hi folks, I haven’t posted in sometime. I need some audio advice from the experts. One of the speakers in our Roswell cans needs replacing. It’s a 6.5” enclosure with Polk Audio MM652 6.5” speakers. The cans have a integrated grill with built in LED’s. So we need a replacement speaker that does not have the tweeter built into the grill; it won’t fit in these cans. The speaker and tweeter need to be all one piece. We have two of these cans driven by a dedicated MTX Thunder TM452 amp (4 Ohms RMS Power Output 45W x 2). A few options presents itself. Keep the current cans and replace the speakers. I’m looking at the Kicker 45KM654 (power range: 2-65 watts RMS: 195 watts peak power) or change the cans and go with a new set of cans such as the Exile SXT-7 (4 pms 250 watts RMS and 500 watts peak).
We strictly surf and all we want is to be able to hear music at that distance.

Thoughts?
