I think he acknowledged in another post that the Klipsch are measured only around 90dB or so sensitive. Should still be sensitive enough for his bedroom and likely volume levels. But whether they will sound good to him or not is another story. What kind of budget are you looking at for speakers @songmic? Triangle is another brand of speakers that have relatively high sensitivity bookshelf speakers, although not as high as the Klipsch, but still likely ok for your application.
