BDR PUCKS & BDR PITS are available in MK3 and MK4
.  They are designed to serve a variety of functions in one product providing unprecedented versatility to the audiophile.  The PUCK and the PIT are approximately 2.75" diameter, and of the same construction as The Shelf.


The PUCK has 1/4"-20 tapped on both sides.  The PUCK can be used as a cone cup using the countersunk hole, placed against a speaker or component with included studs or screwed together with the Cones.


The PIT has 1/4"-20 tapped on one side and dimpled on the other for use as a cone cup.


Both come in 2 dimensions: 2 ¾” w x ¾” tall; 2 ¾” x ½”  Tall                                                                                                                

MINI PITS: small size makes it ideal for placement in space restricted areas or where a smaller form would be more aesthetically pleasing.  

Available in MK3 or MK4 1.75" Diameter.


 BDR'S JUMBOis designed for use with the biggest, heaviest components, has a special combination of height and width giving it exceptional stability and outstanding vibration control capabilities. Thicker than a Source Board, but only 3.5" wide, Jumbos are a flexible & cost effective alternative to a large Source Board, allowing them to be used in a wide variety of applications.

Jumbos work exceptionally well under Reference level components, heavier speakers, large subwoofers, racks and we even recommend Jumbos be used as amp stands for large amplifiers. Add a set of BDR PYRAMID CONES for even greater isolation.  Jumbos provide world class vibration control at a very reasonable price. There is virtually no application a Jumbo cannot be used for. With virtually no upper weight restriction and a seemingly limitless ability to remove haze and grunge from anything it supports, Jumbos reveal the absolute blackest backgrounds, deepest sound staging and rock-solid images. Available in two configurations, Pit or Puck: Pits are the more flexible design, 1/4"-20 tapped on one side and dimpled on the other for use as a cone cup; Pucks are 1/4"-20 tapped on both sides. The building blocks of BDR’s vibration control system, Jumbos are based on the same technology used to create BDR's flagship product, the Shelf. Jumbos are extremely effective when used on their own and when used in conjunction with Cones or a Shelf offer even greater performance.

 Dimensions: 3 1/2" Diameter x 1 1/2" Tall
