This firm yet loosely crosslinked material is formulated specifically for blocking mechanical soundwave energies. Wide footprint gets a good grip and provides excellent lateral stability. Each Big Fat Dot supports and isolates from five to more than 200 pounds (90kg).

Big Fat Dot is 1-5/16" (33.3mm) diameter by 1/4" (6.4mm) thick. Perfect for floor-standing speakers, monitors, loudspeaker and stand decoupling, module decoupling, subwoofer, electrostatics, amplifier platforms, equipment racks.

Other sizes:

Small Fat Dot: 3/4" dia. x 1/4" thick

Square Fat Dot: 1.06" square x 1/4" thick

X-Large Fat Dot: 1.5" dia. x 1/4" thick

Giant Fat Dot: 1.75" dia. x 3/8" thick

Big, Small, Square, and X-Large Fat Dots are the same thickness and can be mixed and matched, or stacked, for unique applications. Use only as an interface between broad, flat surfaces (for use between spike and flat surface, use Herbie's Decoupling Glider or Cone/Spike Isolation Bases. For use on carpet, use Herbie's Fat Gliders.)

Fat Dots are not weight-specific. The major factor is the amount of vibration-blocking "beef" involved. Because of the wide variation of vibrational environments Fat Dots may be employed in, specific recommendations are not always possible. Various Fat Dot sizes have a lot of overlap in their capacities, so choosing between them in many cases in not critical. Standard Big Fat Dots, however, have proven to be particularly effective throughout a wide range of vibrational circumstances and loudspeaker types. Square Fat Dots are very popular as an isolation and decoupling interface between monitor speakers and stands (four under each speaker cabinet is recommended).

Adhesive: Monitor speakers often sit on small stand plates, causing a potential for a speaker being accidently bumped off the stand. Blue Tac is a common remedy. Though achieving some isolation benefit, this material induces some linear compromises, sonically falling significantly short compared to Fat Dots.

dBNeutralizer Fat Dots are available with a mild pressure-sensitive adhesive applied to one side or both. Though this unique adhesive makes only a moderately strong bond compared to conventional pressure-sensitive adhesives, Dots can be difficult to remove if adhered via both sides because getting adequate leverage can be difficult. When separated, the adhesive layer might remain on the stand or speaker instead of the Fat Dot, though the adhesive layer and Dot can usually be repositioned quite easily. Adhesive on one side only is recommended whenever appropriate.

Sticky Big Fat Dot and Sticky Square Fat Dot are the same as Fat Dots above (6.4mm thick), with the added adhesive not increasing overall thickness significantly.

Dot’s of wonder

I didn’t realize how much these 4 little dots would change the sound in my system. I would never believe it until I heard it. Cleaned up the bass quite a bit. Let individual instruments be heard.

Fat dots on amp stand

Happy to report that these work as advertised. I put these between my metal amp stand and the custom made resonance control platform that sits on it. I don’t think I realized before I put these in how much unwanted ringing the amp stand was contributing to the sound of my system. I’m wary of squishy pads that turn the sound into mush, but the fat dots avoid that problem.
