Franc Audio Accessories Ceramic Disc Isolator feet

Energy control is a large part of reproducing music with audio equipment; every element of a circuit, chassis, cone or cabinet has a resonant frequency, a pitch at which it will vibrate to a greater extent than others. Designers use a wide variety of methods to minimise this because vibration in the hardware introduces distortion to the sound waves being produced. You can put virtually anything under a turntable for instance and it will probably change the sound quality, this is easy to understand because a turntable stylus is trying to measure very small vibrations in the vinyl groove. What’s harder to get your head around is that capacitors, resistors and chips are also affected by vibration, and it seems that no matter how much mass is used or how stiff the casework is, changing the support changes the sound.

Paweł Skulimowski is a Polish mechanical engineer and amateur drummer who has been making the Franc range of isolation products for over a decade now. He makes furniture, bases and feet and the latter are particularly professional in build and finish. According to the website, “He has discovered a technique of joining really hard and stiff ceramic materials together with light aluminium alloy and elastic plastics. All parts are precisely CNC machined to give great quality and consistency.”

There are two types of Ceramic Disc Isolator feet in the Franc catalogue; two models for electronics/turntables and two for loudspeakers, while the latter can also be placed under equipment racks. The least expensive is the Ceramic Disc TH which is sold in sets of three or four and stands just over 30mm high. The base is loose but does not come away and there is a proprietary and unspecified ceramic interface within. It has a hole in the top that would act as a spike receptor but the top plate is 44mm in diameter so accepts most sizes of component foot too.

The Ceramic Disc Classic stands 45mm high and is 68mm in diameter at its base and here the top cap is free floating and can be removed to reveal a ceramic ball in the middle of a carbon fibre spider. The top cap is covered in smooth plastic and is 46mm in diameter, the idea is that the base of the equipment rests on the foot directly, bypassing the equipment’s own feet. This foot is available in sets of three as standard, other quantities on request.

The two loudspeaker feet are defined by size, Slim and Fat, with the smaller model coming in at 25mm high by 59mm in diameter at its largest. These are shown to contain three ceramic balls within them and like the TH feet have a central spike locating point on top and a foam rubber skin on the base, they feel more damped than the equipment feet but there is a bit of movement in the top cap. The Fat Foot lives up to its name by standing 45mm high with a similar 68mm base to the Classic, again it has a central spike locator and rubber covered base.
