Similar Carbon Fiber Composite Disc Product

Image: BDR LM Disc Carbon Fiber Isolation Pad

The design of the 40mm x 10mm Carbon Fiber Disc appears to be identical to the BDR LM Disc Carbon Fiber Isolation Pad priced at $29 each via MusicDirect. However, the size of the BDR product is a smaller 38.1mm x 8.7mm (1.5" x 0.34") disc, whereas the somewhat larger generic 40mm x 10mm Carbon Fiber Disc is priced at $3.50 each when purchased as a quantity of 8 via eBay. If the the sonic benefit of the BDR product is trustworthy, I can only report that I find the 40mm x 10mm Carbon Fiber Disc to be an effective vibration control device, which requires very little cash outlay including the anti-skid, mild decoupling pads that make it an effective and practical vibration control device, IME.

As for the use of "glue", a resin material is what makes the use of carbon fiber for resonance control purposes possible. Resin impregnation is the "composite" aspect of a carbon fiber composite material. Otherwise, carbon fiber is useless without the use of resin within the structure of the design, including the vital aspect of rigidity.

For those with stand-mount monitors, I highly recommend that folks try a set of the 40mm x 10mm Carbon Fiber Discs with a 40mm Herbie's Audio Lab Thin grungebuster Dot (black version, with optional adhesive backing) adhered to both the top and the bottom of the disc. It's the best configuration I've tried as an interface between the bottom of a loudspeaker, and the top of a speaker stand, IME.
