Editors' Choice Award - The Absolute Sound
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.
Award-Winning Performance
Blu-Tack won an Editors' Choice Award from The Absolute Sound magazine.
TAS calls Blu-Tack "the original acoustic putty and adhesive from Bostik of England that damps resonances and mechanically couples a compact speaker to the top plate of its stand. Sonically you’ll hear tighter bass and improved image. Considered 'a flexible semi-liquid that behaves like a solid,' it also offers a safety bonus by preventing a stand-mounted speaker from being inadvertently toppled."
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.
"Not Subtle, a Significant Difference"
"My speakers are Neat MFS and recommended by Neat to be seated with Blu-Tac. I recently peeled off the Blu-Tac, re-rolled it, and reseated the speakers," reports Blu-Tac user Elfer in the Hi-Fi Corner at community.nairmaudio.com, June 2020. "
"The difference it made was incredible, more solidity to low frequencies, cleaner midrange, and opened up the soundstage. Not subtle, a significant difference."
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.
"The Bass Had Become Remarkably Cleaner and Faster!"
"Bass travels with ease down into the floorboards and the stand can vibrate with big bass sounds. I became painfully aware of it when a panel on the back was vibrating quite badly on one film that I was watching, so I Blu-Tack'd the plate," reports Rabbit, diyah.boards.net, July 8, 2017.
"That cut the rattle down and then four blobs of blutak were put under the soundbar itself, so that it was in effect, 'stuck' to the glass plate top."
"Not only was the rattle gone, but the bass had become remarkably cleaner and faster!"
