In Reply to: Speaker Isolation posted by Chris K. on December 11, 2004 at 08:09:13:
My speakers sit on DIY roller blocks, which are rigidly coupled to the top of a Symposium clone, which is rigidly coupled to the wood floor thru the carpet via brass spikes.This setup is very effective. The rollers block a large amount of vibration from entering the clone. The mostly vertical vibes that do make it to the clone are somewhat attenuated by the clone.
The fact that the speaker is free to move back and forth (or any other direction in the horizontal plane) is a complete non-issue. The weight of the cabinet compared to the weight of the moving drivers is an extremely large ratio, so any actual movement of the cabinet, even during loud passages at max volume, is only a tiny fraction of a 20kHz wavelength - this displacement is microscopic and therefore not sufficient to generate any audible doppler effects.
A sometimes overlooked effect of decoupling your speakers from the floor is that it helps, to a large degree, to break the feedback loop between your speakers and electronics.
