Isola (Vibration Decoupler)
Vibration isolation feet with suspension structures housed inside the birch plywood casing. The soft leather on top serves as a cushion between the Isola and the device above. The suspension allows the casing to move freely both on the horizontal plane and vertically, effectively decoupling the vibration transmission from the base to the top - or vice versa.
Suitable for placement between the loudspeakers and the TV shelf to eliminate audible resonances from the TV shelf, or under other vibration-sensitive devices to improve sound clarity.
Each Isola has a 6.5kg max weight capacity. Handmade in the UK and calibrated with care.

Vibration, filtered.
There are two ways in which vibration can be transmitted: Airborne and structure-borne. For Airborne vibration, there isn’t much one can do about it apart from putting the vibration source away in a separate, well-insulated room. But for structure-borne vibration, we can tackle it with mechanical filters. Inside each Isola, there are 3 sets of damped suspension, allowing a small degree of movement for the object on top in both the horizontal plane and the vertical direction, while providing damping to dissipate the vibration energy. This controlled isolation prevents mechanically induced vibrations from propagating through supporting surfaces and back into the equipment. As a result, unwanted resonances are reduced, leading to cleaner, more accurate performance.
The clarity you deserved.
The Isola was originally developed for some of the earliest Fidelia customers who needed to place their speakers on TV shelves, using 3 Isola units under each speaker helps eliminate unwanted vibrations and resonances in the shelf. Customers have consistently reported a noticeable improvement in clarity, particularly in the bass and lower midrange regions. Isola is also effective for other vibration-sensitive audio equipment, such as turntables. The figure below shows an example of accelerometer measurements in the horizontal direction taken on a TV shelf with and without the Isola.
We even use it for our measurements!
At Audio First Designs, we provide loudspeaker measurement services using a Klippel NFS. The speaker under test is placed on the machine's platform, and a robotic arm holding a microphone scans the acoustic output around the speaker. In some cases — particularly with a large woofer in a not very well-braced cabinet — the mechanical vibrations of the speaker can be transmitted to the microphone via the robotic arm, compromising measurement accuracy. By adding Isola to the setup, the fitting error is significantly reduced during data processing, ensuring highly accurate, reliable results.
