"45" series

Signature Series Audio Racks

This design has remained unchanged since the first units were sold back in 2001. Many of our customers have been happy to find out that over eight years later they can still add more shelves to their existing rack, and everything looks the same and fits perfectly.

Many other companies have come and gone in that time or made improvements that make the old stuff obsolete. Not so with our 45-Series racks. It's far from becoming a boat anchor, and it's nice to know that it's so strong and heavy, that you could actually anchor your boat to it!

Our famous Multi-Element Granite Platforms:

The approach is simple and well executed. With just three basic material layers it is easy for us to optimize the performance and eliminate the "muddy" effect that occurs when too many layers are used in a constrained layer system. After all, if you need more than three layers, then you're probably doing something wrong in the first place.

Independent of component weight - whether it's a massive 300 pound amplifier, or a sensitive phono stage, the results are satisfying and predictable! Plus, they are tolerant to a wide range of after-market coupling devices - allowing you to "tweak" your system any way you like it.

Available with Cherry trim. $75.00 for the 18x18 and $100.00 for the 19x24. Comes standard with 18x18 black bottom platforms.

The X-Frame:

The shelf support-frame utilizes heavy-gauge steel tubing fully welded at the center point to increase torsional stiffness. The attachment plates are fabricated from 1/4 inch steel plate. Steel, like granite, rings like a bell unless it is properly damped, so the weight of the granite rests at points that interfere with the linear resonance of the tube. When filled with sand (or lead shot), the frame becomes about as sonic as "a stick in the mud" yet it continues to couple energy toward the floor. Leveling is provided by a 1/4-20 conical set screw and jam nut at each leg of the support frame.

Your choice of Black, Silver, or Gold for no extra charge.

The Columns:

These 45 mm square columns weigh in at nearly a pound and a half per linear foot. They are much stronger than similar-appearing columns used on our competitors products and also use larger fasteners. The precision extruded aluminum columns, borrowed from other industries, are typically used in the manufacture of machinery frames. Aluminum is a good choice for audio racks since it transmits vibration energy quite well down it's longitudinal axis, where it is easily drained by your floor.

The Caps

Commonly referred to as "end caps" on most racks, these precision machined units serve several functions on the Adona rack. Obviously they add a "finishing touch" to the top of the column, but more importunately they provide a means of coupling (or decoupling) and allow platforms or additional rack layers to be placed above the columns.

We use plain top caps on the top level of all racks. If you would like stackable top caps (we call them receptor caps)on the upper level you may do so for an extra $25.00.

The Footers:

The primary function of spiking is to focus the weight of the rack onto an infinitely small surface area, although some floor finishes make the use of such devices impractical. Therefore, we offer optional floor discs, as well as glides and casters.

All racks come standard with either Gold or Black-chrome 1 1/2 inch brass cones. Floor protectors are available separately. Please see ad.
