Theta Series
The theta rack by SoundFoundations is a classic spider rack design incorporating a Steel X frame for each shelf providing extreme rigidity and support. In addition to this it provides an option of going truly “shelfless”.You can place your electronics directly onto the cross members, thus removing “shelf signatures”. Alternatively those who want shelves can just place and level them on the X frame.
Our multimelement platforms are superb for this purpose
With this design we truly enter the realm of high end audio. The rack is neutral sounding across the entire audio spectrum and known to add no coloration. In fact it helps in achieving a life like soundstage with incredible focus and separation.
The columns are Heavy gauge beefy cross braced Extrusions with extra large dimensions for an aggressive look. The rack makes a Solid statement. Bring on those monster Krells and Levinsons. It’s nice to know that out theta series racks are so strong and heavy, that you could actually anchor your boat to it!
Theta Rack “Signature Series”
This series comes with 4 oversized heavy gauge T slotted pillars into which 4 Steel X frames Slide into. Each is infinitely adjustable and supports our multielement shelves incorporating our tested anti resonant technology. Each shelf has a capacity of 250 Pounds (that’s over half a ton per rack!) and measure 18*18 inches (this can be customized but is adequate as long as the equipment feet land in this dimension).It is most likely one of the most rigid racks anywhere. Each X frame comes equipped with leveling aids and associated hardware for fixing to the side pillars.

Theta Rack “Reference Series”
The reference series is a stackable version of our signature rack which goes a level further in isolating your equipment individually and independently. The rack is suited for use in serious high end setups. The open framework construction provides clean airflow and access to the components 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 footers ensure stability. The resulting “stack” behaves much like a one-piece rack. Another important feature is the ability of the user to add a level when needed or alternatively even join two racks to form one whole structure. The resulting structure fits and looks the same always.
With the serious audiophile in mind, this modular AV rack employs the latest technology in design and materials to unleash the full potential of your system. Although designed primarily with function in mind, it looks pretty “cool” as well!

- Genuine granite shelves, bonded to damping material, eliminate resonant waves.
- Mathematically calculated support points further reduce shelf resonance
- Super strong one-piece mig-welded tubular steel frame for each shelf.
- Vertical struts and T-Slots are more robust than those used on competitive units.
- Sand or shot fill-able for increased damping. Although this is not necessary.
- Modular construction may be expanded vertically or horizontally.
- Assembles in minutes using provided tools
Our Multi-Element Granite Platforms:
Our concept is sound, combine the benefits of different materials using and focusing their best acoustic properties, at the same time compensating for their ill effects when used individually. Each stone slab is bonded to a 3/4 inch thick anti-resonant substrate. The notable aspect is the way energy is transferred back and forth through the multielements to achieve a flat response throughout the entire audio spectrum Collectively the shelf translates into a sonically neutral platform providing an unparalled sense of realism to music
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 essentially coupled through the supporting frame and on to the floor. The result is a “rock solid” and quiet platform for your components. You’ll hear the true timbre of the music with no added coloration.
Independent of component weight – whether it’s a huge heavy power amplifier, or a sensitive phono stage, the results are fantastic. In addition to this they can be paired well with a wide range of tweaks as seen in our accessories section.

The Support X Frame:
Since aluminum is used for the vertical columns, we use ferrous metal for the horizontal beams. Rack frames made entirely of aluminum exhibit phenomena referred 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. Our rack frames are among the quietest in the industry.
Our 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.
The Columns:
The columns are huge 45mm cross braced precision extrusions especially designed to be “ring free”. The cross bracing throughout its inner length adds rigidity and strength. The T slot running along its side serves dual purposes. Not only does it allow us to lock the X frame in place at any desired height but also allows us to actually join two racks to form one coherent framework. Aluminum is used for its neutral signature and hence is perfect for audio racks. The heavy gauge column is designed to transmit vibration energy quite well down its longitudinal axis, where it is easily drained by your floor.
The Capitols
Also referred to by us as “End Caps”, these serve dual purposes especially in the reference series. Not only do they allow us to hold together the top most shelf in a rack they also add a touch of class. In the reference series the capitols are precision machined components that 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, thus allowing it to function as a diode and transmit vibrations and energy only in one direction-rack to the floor. We have various kings of footers on offer however we generally use only the isosphere footer or the SureSpike both of which are CNC machined marine grade SS components. Spike feet to protect your floor are also available
