Polk RC85i or RT-65 or LS-65 - which is the right speaker for me?

Serendipity

So I've been looking at the RC85i, 65-RT, and 65-LS and was wondering which is the warmest sounding speaker of the bunch? I'm looking for a warm, smooth, and relaxing sound instead of a detailed and "edgy" sound. I would try all 3 speakers, but once you cut holes for the RC85i it's kinda hard to go back to the others - short of changing the drywall. As a result, which speaker is the best for easy listening, and which provides the most comfortable sound?

Thanks all!
