PSB Stratus Goldi. They will work well in a large room and with your amp they'll play really loud and should take a lot of abuse without damage unless you change to a smaller amp and run out of power. They are great party speakers and pretty good at lower levels.
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.
