Blu -Tack Under Bookshelf Speakers?

If your speakers are rocking and rolling on their stands or bookshelves, blu tack is only going to hide the problem. Your speakers may not be all over the place after you glue them to whatever, buy all the reasons for that rock'n and rolling are remaining within your speakers. You want all that nasty resonance to go to mother earth. I'm a coupler, obviously. Place (3) 1 1/2" cones (i use audiopoints) under your speakers and the same under your stands. Bookshelf speakers don't belong, (anyway), on a shelf. Unless, of course, you want to kill your sound. peace, warren
