Our shelves are made from two layers of pressed glass sandwiched together and separated by a butyral sheet and an isolator. The total thickness is from 1cm.

Shelves for audio need to be rigid and should act as shock absorbers to prevent the negative effects of passive modulation. These requirements are achieved by effectively sandwiching layers of a suitable material together and by providing adequate support with isolating pins and discs.

Shelf material and the sandwich structure

We use materials with high natural frequencies. These natural shock absorbing materials ensure that resonance and vibrations are low, even at high volumes (90d) There are a number of audiophiles that are convinced that materials of high mass (marble, granite, steel etc..) are suitable for making audio shelves. However, materials of this nature present no obstacle to vibrations.
Artesanía-audio has never used these materials in the design of its shelves. This is because they are difficult to "sandwich" together with shock absorbing materials such as elastomer sheets, fibres or bitumens.
Artesanía-audio has stuck to these sound guidelines and has always incorporated a "sandwich" design in its products that contain shelves. In this way the MDF and neoprene shelves of the older models were created, as were the double layer pressed glass shelves that are used in current models.

Shelf supports; discs and pins

Finally, the shelves are supported on polyamide isolating discs and neoprene pads that provide maximum absorption and block (also preventing horizontal movements.) In turn, these discs are supported on adjustable steel pins that rest on the metal frame. The combination of these various gradients reduces the speed of propagation (to reduce transmission) and this, together with the different absorption coefficients, improves the overall effectiveness of the shock absorption.
Each shelf is supported on four distinct isolating pins. The mass and weight distribution of any kind of equipment is not uniform and through experience we have found that support using less than four pins is not effective; it does not provide adequate stability or allow the exact calibration in the shelf level and height once the equipment is put in place.

VERSIONS Normal shelf (50.5 x 40cm) Special deeper shelf (50.5 x 48 cm) suitable for larger electronic units. Other sizes can be made to measure upon request.
