These new mounts do a fantastic job of keeping the speaker and the sound and vibration sources, without coloring the other speakers mounted to the same struts. Fantastic! Again, another home run for IsoAcoustics. They make big promises for the sonic and detail improvement, and deliver beyond expectations. No amount of room tuning or compensation software can fix fundamental energy wave problems. These isolators should be on every system before even getting to the tuning of ones room. Well Done Iso-Acoustics! Another big product!”
