This is a custom Adona equipment rack I ordered a couple of years ago. I have made changes to my system and do not need it anymore. It has large brass chromed spikes which are adjustable for uneven floors. This is a triple width rack in black. The platforms are black granite slabs with a sheet of medium density fiberboard (MDF) which has excellent anti-resonant properties. Since it's moduler you can configure it to be a 3 shelf vertical equipment rack. This rack will be broken down to be boxed up for shipping. Below are details from the manufacture.
Asking Price: $550.00
New Retail Price: $1,170.00
This is essentially a stackable version of the popular AV45G audio rack and features the same highly-effective resonance-damping shelf system. The open framework construction provides ample airflow and access to the component while the granite and metal set-off its good looks. Being modular, it is fully customizable and upgradable. But there's much more behind this design. The high-mass cones effectively couple each level to one another. Concave receptors ensure stability. The resulting "stack" behaves much like a one-piece rack. Additional levels may be added as needed or as budget permits. These units are compatible with the entire AV45 series of modules.
Our famous Multi-Element Granite Platforms:
Granite is well-known for its ability to maintain precision flatness and has sufficient mass to naturaly resist motion, not to mention its stunning beauty. Natural stone however, will ring like a tuning fork unless certain measures are taken.
We combine the granite slab with a sheet of medium density fiberboard (MDF) which has excellent anti-resonant properties (that is why MDF is widely used in the manufacturing of speaker enclosures). The bonding is achieved through the use of our proprietary anti-resonant conduction material. Our secret is is in the way energy is transmitted back and forth between the different materials. The material mis-match is deliberate and well executed. Next, we calculate the best points in which to support the slab such that it tries to oscillate outside of the stones natural resonant frequency thus affecting its ability to "ring". The granite is essentialy coupled through the supporting frame and on to the floor. The result is a "rock solid" and quiet platform for your components. You'll here the true timbre of the music with no added coloration.
