Review on Low Profile 1/4" Thick Isolation Pads - Eliminate Vibrations & Movement for Speakers on Speaker or Bookshelf (Set of 8, 2" Round) by Amber Powell

I love these pads. I bought them to put under a pair of large carpet speakers (Jensen JP 1200) in hopes of reducing noise transmission to occupants of neighboring apartments and they did a great job. I've found that my bookshelf speakers playing jazz get more noise through the floor than the JP 1200's sci-fi sounds. I'm buying a second set of bookshelf speakers. If you like loud sound but don't want to be bothered, then this is for you!
