I just bought the level three towers and the center from Home Theater Direct and I was wandering since these have a rating of 90-91 DB, should it not take less power to put out the same volume as my other speakers that were rated 87-88 DB. My previous speakers were what came with the Kenwood 504. Could it be that these are books versus towers? I notice I can really power up my new ones to way over what I would listen at and they will sound good with no distortion but I had the mind-set that it would take less watts to get them there? The center is like four times bigger now too. Any one know what I should expect. Are my expectations false.
