OMEX Symphony 3A - set of 4

OMEX Symphony 3A - set of 4

Symphony is a range of isolation devices, comprising of two performance levels. Symphony A and Symphony S have been crafted as a clear upgrade to the existing supports on audio electronics and under floorstanding speakers or speaker stands. Each level has two tiers of performance – a 2 layer variant (a great space saving option) alongside its more advanced 3 layer counterpart.


Both Symphony A and Symphony S share the same design principals, yet their material selections are radically different and can be very clearly distinguished in terms of their colouring, weight and performance.


Micro Grooving

Each Symphony device begins with an outer micro-grooved upper and lower disc, whose job it is to grip the underside of electronics and the surface of a rack shelf more effectively than that of a smooth surface. This gripping effect has greater ability to contact and transfer resonances from the equipment and begin the process of eliminating them from the delicate circuitry in one direction and the equipment supports in the other, enhancing shelf to shelf isolation.


Material Selection

Symphony A is machined from an Aluminium Polymer Compound (APC). The properties of this compound allow for fine tuning of the structure’s rigidity and ability to dampen resonances, too soft and it provides no structural strength, too hard and it will simply ring like piece of glass under stress.


Getting this balance just right allows for the taming of induced oscillation from the material, which can be fed back into the delicate electronics. So, the device doesn’t take one frequency of resonant activity, interact with it and send back a slightly different resonance which then displays in the music and colouring the sound. For example: removal of bass bloat – traded off for a high-frequency ringing, which displays itself as distortion or an etched brightness. Making it far more effective a material than a traditional aluminium structure, often featured in other isolation products.


Symphony A’s discs also differ in APC density to that of its APC tuning fork in order to critically dampen the upper disc and allow the bearings to efficiently dissipate the unwanted vibrations into micro amounts of heat.


Tuning Fork

The centre piece of each upper disc is a carefully implemented tuning fork. This design encompasses a varying metallic density to the disc structure itself. In order to dampen and control the flow of resonances, this tuning fork sits inside an internal chamber within a central spine.


For isolating electronics, Symphony’s tuning fork resides below the top of the device to ensure that it itself is not activated by first-hand resonances, allowing it to perform it’s job in damping those resonances prior to reaching the ball bearing decoupling points.


For use with speakers, Symphony can accommodate a spike centrally within its tuning fork. The top layer becomes more of a weight loaded funnel using the top disc as a means to freely resonate off any initial high frequency resonances with the central spine ending the speakers interaction with the floor and giving it a new coupled point of reference which then becomes decoupled through the bearing points, allowing for a cleaner, tighter and more concise sound.


 Ball Bearings

Residing between each disc of the Symphony layers are an arrangement of ball bearings. Symphony A uses a stainless steel option (which can be upgraded to ceramic). Their positioning allows for resonances to be driven into their pathway, where they can convert and dissipate this energy as small amounts of heat. The bearings have CNC cups machined into each layer for them to comfortably sit within and remain unfixed for maximum effectiveness. 


3 Layer - Additional Centre Disc

The 3 layer version within each of the Symphony ranges has further technical resonance control abilities. This additional centre disc can be referred to as the “scrub layer”. Its primary role is to remain completely decoupled from the top and bottom discs and can be concentrically swung laterally from the vertical arrangement, with its only points of contact being the bearings in between each layer, which are staggered in this 3 layer arrangement. 


This implementation acts as a barrier between rack vibrations and electrical resonances, greatly enhancing the devices abilities and functionality.



As OMEX’s Symphony Isolation devices are unfixed, it would be quite tricky to lift a weighty speaker with one person and carefully arrange the footers underneath without some potential threat of ball bearings being knocked out from between the discs and rolling across the floor. So, to aid with placement under speakers or other weighty and awkward components we include reusable, non-permanent, no-residue circular stickers with each product.


Simply peel and stick one of these to two opposing sides of Symphony, install without having to be concerned of the layers coming apart, then simply peel each circular sticker back off and replace them onto their waxy paper backing for use again in the future.



Symphony A will accommodate a weight of 45kgs per device.
