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.
