Hello, I've been doing quite a bit of searching for compact speakers to use in my den. I've focused my search on small bookshelf speakers, rather than satellites, and I've taken quite an interest in the Polk R15. Does anybody have experience with or opinions on these speakers? These will be used as mains, and I plan to fill in the low end with a small powered subwoofer. The den is not a very big room, and we usually won't be listening at loud levels. Due to space constraints and the strong influence of wife-acceptance-factor, I probably cannot step up to the R15s 'big brother' the Monitor 30. And given the sale prices the R15s go for, I can actually buy several pairs of R15s for the price of a single pair of 30's (or any other speaker I've looked at). Do the R15s sound like a pretty suitable compromise for my situation? One other question, regarding speaker placement. These speakers will have to go in the top shelf of an entertainment armoire. Therefore, I will only be able to space them about 3 feet apart. At that close of spacing, is there any point to getting a center speaker?
