HiFi Speaker Isolation Pad 3D print model

Aviation-Inspired Audiophile Solutions.For audiophiles, HiFi enthusiasts, and anyone considering upgrades to their audio system. I have developed new product designs that will provide these solutions at minimal costs, inspired by my work on Aviation projects. Years ago, I had the privilege of helping a start-up company develop their new line of high-end amplifiers. My primary role was designing the amplifier chassis.

In addition to the main chassis designs, I needed to think about the feet and how to develop a solution that would provide adequate isolation to reduce vibration and resonance. I spent a considerable amount of time reviewing various commercial options. Some of these designs were excellent but quite expensive, while others honestly lacked proper design input. Like everything else audio related the choices are vast and usually priced beyond the means of the average HiFi enthusiast. This presented a challenge, and this is my solution.

Speaker/Amplifier Isolation/Anti-Vibration Mounts:

In aviation, there are numerous instances where damping and anti-vibration measures are essential due to the nature of aircraft operations. A clear example is the landing gear, which requires effective dampening. Additionally, damping is important for the installation of instrumentation panels and shock absorption, such as with the tail wheel of the Tiger Moth. This particular case is noteworthy because the innovative design of stacked metal discs interspersed with shock absorber pads inspired my solution, as described below.

The following images illustrate my solution for an effective Speaker Isolation Mount, which also works for isolating amplifiers (integrated, pre-amp, and power amps) up to 8 kg. (2kg/pad).

The Isopod-2 is made up of four externally stacked rings and four internally stacked rings, all featuring three layers of silicone o-rings. At the top, there is a composite buffer made from rubber and cork, and the base is constructed from a similar material. The development of this final product took over three years, during which various prototypes were created and tested to achieve this design.

I 3D printed prototypes for all main rings using either standard resin or ABS-Like resin material. I haven’t tested them with alternative engineering resins, but I’m confident they will work well. They are designed so they can be arranged flat on the printer bed and printed without additional support. The size is deliberate to suit even the oldest 3D resin printers out there.

The main purpose of the stacked arrangement is to stabilize the central core and provide sufficient O-rings for adequate load-bearing capacity. The product comes with a series of 2D detailed drawings to assist with assembly, which also provide information about the accessories and fittings.
