Townshend Springs under Speakers

Until you put his speakers on Podiums, and hear the profound improvement. Okay maybe not even then. But those still open to learning and with a desire for better sounding systems regardless of what else it might imply, those people will definitely hear it and be happy and want it.

Read actual user comments. Wobbly floors, solid floors, concrete floors, does not matter.

The physics is the same regardless of the speaker manufacturer.  My experience with spikes vs. decoupling (using Herbies products and later springs) led me to believe in the benefit of decoupling on both suspended wood floors and on grade-supported concrete slabs.  The effect of decoupling/springs could be different and/or more substantial for speakers supported on suspended floors than for those supported on concrete, but IME it is the better performing option as discussed by @oldhvymec below. 

That's what I thought.

For those who might want to read R. Vandersteen’s comment:

I have tried to duplicate Townshend’s test results but was unable to measure the amount of movement of the floor in the lab or my home (was unable to sinc the test with a earthquake even though I am in Calif). Both locations are concrete floors directly on the ground. If ones floor has significant tympanic movement from some source (music, subway, train, freeway ,etc) spring isolation tuned to a very low frequency may allow the speaker to more accurately pressurize the room with music’s information. In my rooms it caused dynamic compression and smearing because the speaker enclosure moves. It does make the sound less bright and the sound stage gets more diffuse (larger but less defined) which may sound better with some speakers especially if like most speakers the tweeter is too bright. The ultimate goal is for the speaker to be held in space as rigidly in space as possible so that any movement in any of the speakers drivers is not modified but a facsimile of what came from the amplifier. Like usual this will vary in different situations but in IMO 3 points works best in most situations.

@stringreen, you seem to want to try Townshend podiums. Do it. Why not? Report back once you have them installed.

Isolation below speakers works from my experience...but it greatly varies from speaker to speaker and from room to room.
