Has anyone had experiences good or bad with speaker isolation or isolation in general ?
Hardness of audio cone materials. The numbers are on the Mohs scale of hardness where 10 is diamond, the hardest material. Notice how the hardness of these materials correlates with the relative effectiveness of various cones I posted yesterday in terms of sound quality improvement.

erik_squires, the Townshend podiums on a different level better than the isoacoustic Gaia, the iso acoustic only isolate down to I believe 20 Hertz the Townsend podiums isolate down to three Hertz so with the guy is your speakers are still shaking from the vibrations of the Earth, go read up about it you'll understand what I'm talking about the podiums are three times as expensive as a guy but everybody that's tried both has said that the podiums are on a different level better. |
