Blu -Tack Under Bookshelf Speakers?


I heard that Blu-Tack is a good substance to put between bookshelf speakers and stands for absorbing resonance. How much would I need to use on a 8"w x 11"d speaker on a 8"x8" platform? Do similar substances like FunTac and Elmer's Tac n' Stick work the same? (I'm having some trouble tracking down the original.)

Thanks in advance for any advice.

An inexpensive alternative to BT is the "like" product under the Dep (Dap?) name. It is also blue in color (approx. $2.50/package) and it does not stain wood like some of the other brands I have tried.

The way I use tack is to apply four balls (half the size of an early pea) to the corners of the stand (then press the speaker down). If the speaker is removed you will be able to see through the thin layers of tack. With this method the speaker does not "rock" as Warren notes. The speaker is held firmly to the stand (moreso than if larger amounts of tack are used).

I have yet to prefer the sound of spiking/coning any of the stand mount speakers I have owned, though this does not mean that you should not give it a try yourself.

Anyway, for $2.50 I would try this first.

I purchase the DEP/DAP product @ our local Mom/Pop hardware store and assume that it is readily available in most areas of the US.

I do couple/spike stands to the floor and also spike equipment shelves to my rack (just have not cared for doing so with the speakers).

I used the Dep for two years on the same speakers (Reynaud Twins in cherry). There was no damage to the finish (I could not even tell where it had been once I removed the tack to resell the speakers).

However, I have not tried it on painted finishes or those with a plastic top coat.

Also, what are concrete Mother's (sound interesting)?
CDC:

I remember seeing these, or something like them, years ago. I seem to recall that their use was being recommended with a specific speaker (perhaps the speaker manufacturer was endorsing them)?

Used to have a pair of soccer shoes with little shock absorber devises that protruded from the edges of the heels/soles. Other than looking extremely odd, they were my most confortable pair by far.
