"Zero G" series

Reference Series Audio Racks

These ultra-high quality audio racks represent the "best of the best" and are an upward design progression based on our highly successful 45-Series racks.

These racks are hand crafted using only premium-grade materials and are computer modeled and stress analyzed for superior performance. Incorporating an extensive amount of custom-machined and fabricated components, the manufacturing cost is somewhat higher than our other product lines, although the performance exceeds that of competitive racks costing much more. Made in the USA!

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.

The Frame Assembly:

Since aluminum is used for the vertical columns, we use ferrous metal for the horizontal beams. Rack frames made entirely of aluminum exhibit a phenomena we refer to as "cage effect". This is caused when vibration energy loops around the rack frame and feeds back into itself. Since this is caused by vibration along the longitudinal axis, simply applying a damping material to the surface won't eliminate the problem.

Try this simple experiment: Take an aluminum extension ladder and drop it on the ground. The loud clang sound you here is an example of this phenomena which is inherent in the sonic signature of rack frames made entirely of aluminum.

The solution is obvious. We simply use a material for the cross beams that has different properties than that of the columns. Adona rack frames are among the quietest in the industry.

The Sub-frame

This model includes two sets of standard frames, plus one set of expansion frames.

These heavy gage steel frames provide superior strength over typical extruded aluminum frames. A precision fixture, used during the TIG welding process, ensures accurate alignment and ease of assembly. Standard color is gun-metal gray.

The Columns:

These massive , 3 inch diameter columns weigh in at over two pounds per linear foot.The precision extruded aluminum columns, borrowed from other industries, and 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 independent platform support brackets:

These attractive shelf supports are machined from 3/4" thick, solid billet aluminum and weigh almost a half a pound each. They accept a wide range of industry-standard devices allowing you to direct-couple or float your platforms. All Zero racks come standard with direct-couple leveling devices.

The Capitals

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.

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.
