I had begun to become disillusioned with my LSi9's and couldn't figure out why. They sounded lifeless, quite "veiled." Then one day it dawned on me. The tweeters were below ear level in my listening chair! Stupid me. Even on 27-inch stands, with the tweeter in the middle of the box instead of at the top, they were just too low. I stacked a few Mosaic record boxes on each stand and put the 9's on top of them. Now the "stands" are 31 inches, although I know I have to get real stands of that height now. The difference is sound is quite substantial, of course. Have any of you guys/gals experienced this? What do you have your 9's perched on?
