Tandem’s Reference Series equipment stands are handmade, fully adjustable, vibration-free and built to support up to 220 lbs. per shelf. Each 3.5-inch deep shelf houses a complex wood and aluminum sandwich designed to absorb ambient vibrations.
Each Reference System shelf measures 27.5 inches wide by 19.7 inches deep, by just under 3.5 inches deep, and supports up to about 220 lbs. Each shelf also serves as an independent unit in a proprietary technology Tandem-Audio calls its Metal Manipulating Vibration System. While resembling a single slice of wood resting in a metal frame, each shelf is actually a complex construct of handcrafted wood veneers around a vibration-absorbing core framed in a cast aluminum alloy electrostatically painted silver-gray.
The unusual core consists of an aluminum-plywood sandwich filled by a layer of 3.22-inch wood cubes meticulously glued to each other by hand. An aluminum plate immersed in a low-inertia metal filling is embedded inside each shelf, and hand-applied veneers encapsulate the whole. The wood cubes absorb ambient vibrations and transfer them to the aluminum plate and metal filling, which lower their resonant frequency out of acoustic range. The racks’ support columns are made of the same aluminum alloy as the shelf chassis, and are veneered to resemble solid wood posts.
Reference System veneers can be custom selected to attractively complement any residential environment. Available woods include African and American walnut, dibetou, mahogany, makore, beech, maple and wenge, as well as exotic varieties like ebony and palisander, and special custom offerings.
