of all of the thoughtful suggestions above, i'd go with the psb stratus golds, which i regularly see used for <$800 or so. they're great and timeless-- might be the best blend of big party-hardy and finesse at that price. alternatively, if you can find some polk rt1000p or rt2000p (which have built-in-subs) for a couple of hundo, they're suprisingly good sounding--more detailed at the high end than you'd expect.
Decent moderate priced speaker for large room
Admittedly this is outside the scope of true high-end audio, but I am perplexed re: chosing a moderately priced, full-range speaker to utilize in a vacation rental house. The room is 40' x 25' w/two-story vaulted ceiling. I would like to use my PS Audio GSA-250 (250 w per ch). I know it's a tall order, but I am seeking the best combo of party level and lower listening level performance, at a price that I won't have to loose sleep over.
