 | Brand | SYMPOSIUM | | Product | RollerBlock JR set of 4 | | Introduction | Symposium introduced lateral ball bearing isolation with the original Rollerblock® in 1997; since then, Symposium's Rollerblock® Series 2 has been the standard of excellence for ball bearing isolation in the high end audio industry. Many rave reviews and customer comments reinforced their position as the premier ball bearing isolation device. However, it became evident that there was a need for a lower cost "introductory" ball bearing isolation device designed with the same audio expertise and commitment to quality as the original Rollerblock. Thus, Rollerblock Jr. became a reality.
Description
Rollerblock Jr. consists of of 6 tops and bottoms and 3 center bearings, to make 3 "Double Stacked" isolator/coupler units. Each top and bottom is constructed of black anodized, aircraft alloy aluminum, and has a 1.875" diameter (4.76 cm) and 5/8" (1.58 cm) thickness. These dimensions were carefully chosen to make Rollerblock Jr. easy to use and set up, yet strong enough to withstand the rigors of use under heavier equipment such as large amplifiers and heavy loudspeakers. The special cup interior has been designed so that the top and bottom "sandwich" is stable with the ball inserted in the center, making for easy setup. The bottom and top are flat and suitable for all equipment chassis, as well as flat surfaces and carpeting.
Version 1.1 introduced
After its first production run, Rollerblock Jr. was modified to include a 1/4-20 threaded hole dead center on the opposite face from the cup. This threaded hole allows the Rollerblock Jr. body to be screw-mounted to many existing equipment foot fastener systems, and facilitates secure fastening to Symposium Precision Couplers (this allows making a very high Rollerblock Jr. for clearing extremely high equipment feet, or other applications) or with "hanger bolts" for securing into wood platforms, etc. Also, the alloy material of the blocks was upgraded to a higher grade aircraft aluminum. Cup sphericity and all other geometric relationships were maintained. | | Package | RollerBlock JR Includes 6 Tops (Set of 4) | | | Symposium Acoustics RollerBlock JR Includes 6 Tops (Set of 4) |
