Bostik Blu Tack Tacky Damping Compound

The Easy, Affordable Way to Reduce Speaker Vibration

Blu-Tack from Bostick is a reusable plastic material that has excellent molding qualities. It resists slump, will not shrink, won't dry out or harden, and can be used over and over again. It is excellent for use as a coupling between speakers and stands for eliminating or greatly reducing many types of mechanical vibration and resonance. Non-toxic Blu-Tack will not harm the finish of your speaker, speaker stand, or any other surface, and it can be pressed into any shape.

Tighten Up Those Low Frequencies

Using Blu-Tack with Celestion speaker stands and Acoustic Energy AE1 speakers, Stereophile magazine editor John Atkinson noted, "With the Blu-Tack interface on the Celestion stand, the low frequencies were the tightest and the most tuneful, the lower midrange the most transparent."

In addition to using Blu-Tack with speakers, you may find other audiophile uses, too. Search the web for suggestions, or experiment on your own.

A Little Can Go a Long Way

How much Blu-Tack do you need to use? According to John Atkinson, "If you want to suppress resonances the most, you should use thin pads of Blu-Tack about the size of a nickel."

This package of Blu-Tack gives you a strip of about 3" x 3", which is more than enough for a pair of speakers. Tweaks don't get much more affordable than Blu-Tack.

2019 Editors' Choice Award – The Absolute Sound

"...damps resonances and mechanically couples a compact speaker to the top plate of its stand. Sonically you’ll hear tighter bass and improved image."

Using Blu-Tack with Celestion speaker stands and Acoustic Energy AE1 speakers, Stereophile magazine editor John Atkinson noted, "With the Blu-Tack interface on the Celestion stand, the low frequencies were the tightest and the most tuneful, the lower midrange the most transparent."

"As a rule of thumb, if you want to suppress cabinet resonances the least, you should support your speaker on upward-pointing spikes or cones. If you want to suppress resonances the most, you should use thin pads of Blu-Tack about the size of a nickel. If you want to arbitrarily boost some modes and suppress others, you should use some sort of reactive interface, of which there are a myriad. These results also imply that the choice of the stand itself will have a major influence on cabinet vibration, an effect independent of that of the interface."
