These platforms were made specifically for my pair of Lamm M1.1 monoblocks. They were used from 2000 to 2003 and have been sitting on a shelf since our move to Hilton Head in 2004. The size is 17" wide X 20" deep.
Shipping wt & size is #47 and 24"" x 20" x 8" for EACH BASE.
The "VR" Series isoBASE product line is the newest, most cost effective isoBASE design. This SRA Audio isoBASE has quickly become the best selling isolation device.
The "VR" Series features all of the key design elements used in the acclaimed "Ohio-Class" XL Series isoBASE, but takes a different approach in controlling and eliminating vibrations.
The most obvious difference is the appearance of the main housing. By eliminating the HY-80 high tensile steel "RAFT", used in the "Ohio-Class" XL isoBASE (and the time needed to produce & install this "RAFT"), they were able to do two things.
First, they were able to gain additional room needed for our super rigid build materials to be used throughout construction.
Secondly, it allows for a simpler build process, which drastically reduces unit cost. This is done without sacrificing the performance that high-end audio customers expect from an SRA audio isolation platform.
It's the use of new, super rigid build materials, which allows component specific design, at attainable price points. The "VR" Series isoBASE effectively isolates down to 3 Hz.
These have the optional Pre-base units needed for equipment placed on carpets, these units raise the isoBASE unit off the carpet & allow the suspension to remain active.
