I'm having trouble situating my Front and Center speakers in my new 7.1 setup. I know that most speaker manufacturers recommend to have the front L/R speakers with the tweeters at ear height (with respect to the primary listening position). I also have heard that it is best to have your Center channel at roughly the same height as your fronts for best soundfield integration. However, my Center sits on a mantle that is about 2 feet higher than ear height. It can't be placed any lower because the mantle is above a fireplace, and that area has to remain clear. Thus I can either have my Fronts at ear height, thereby being out of alignment with the Center, or I can have all 3 speakers in alignment but at 2 feet higher than ear height. Which would be the lesser of two evils?
