Blu -Tack Under Bookshelf Speakers?

It all depends; are you having trouble with your speakers sliding off the stands?

You've hit upon the decoupling/coupling discussion thats been taking place here. Some of us think that coupling isn't the best way to go, but if you want to try it out for yourself, just knead a small amount until it's soft and use a little dab in each corner.

Be warned that paint and bad veneer can remain stuck to the blu tack after long use. A friend gouged out divots of particle board from some cheap stands he had blu tack'd to.

The bumpy, no-skid rubber sheeting sold at hardware stores works nicely.

If your speakers are rocking and rolling on their stands or bookshelves, blu tack is only going to hide the problem. Your speakers may not be all over the place after you glue them to whatever, buy all the reasons for that rock'n and rolling are remaining within your speakers. You want all that nasty resonance to go to mother earth. I'm a coupler, obviously. Place (3) 1 1/2" cones (i use audiopoints) under your speakers and the same under your stands. Bookshelf speakers don't belong, (anyway), on a shelf. Unless, of course, you want to kill your sound. peace, warren

Soc:

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).

You can buy a device that adheres to the speaker cabinet and will tune out the cabinet resonances. Unfortunately I can't find the catalog where I saw it (MCM I thought). Spend 15 minutes looking and can't *&!#$@%# find it, sorry.
Vibra-pods under speakers will absorb resonances. But the speaker will not be solidly mounted and there could be problems with imaging.

Everyone wants to have their speakers sound their best. If you use the smallest of the Audioponts in conjunction with the Apcd coupling discs you will achieve this goal..I have done this many times for friends..Tom

Elizabeth:

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)?

I found it, I found it! Check these out:
Tekna Sonic

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.

Warrenh, is there any more-less detailed manual how to chose and use those audiopoints?
I have the same problem with my Revels M20, and Blue Tac doesn't make me feeling good. My stands have their own four spikes on both sides, but I don't use the upper ones - don't want to damage a finish on the speakers. Are coupling discs the solution here? Should the original spikes be replaced with the ones from audiopoints?

Screws.....will always work.
