The room is truly small, I believe 9x11 with 8 foot ceilings. Also I don’t think Klipsch would be a good choice for me with my tastes. I really prefer I nice full midrange and I’m willing to sacrifice elsewhere to achieve it.
I'm normally a proponent of higher efficiency speakers. But in a bedroom system you usually are not playing all that loud and in a smaller room like this the efficiency isn't going to matter much.
Take a look at http://www.fritzspeakers.com
Fritz does excellent work and his speakers are very reasonably priced. They are in the high 80s for sensitivity. I have his smallest set in my bedroom system and my amp makes 5 Watts per channel. My room is larger and I don't come anywhere near pushing the amp hard. A powered subwoofer is nice, but Fritz is very good about getting low frequency bandwidth.
