Vesicular basalt.

An excellent platform into which to render mechanical vibrations is a vesicular basalt slab. Bocchino Audio will supply such slabs to the following maximum sizes:
 

Thickness Centimetres	Maximum perimeter size in centimetres	Maximum Area in square centimetres
6	43 x 25	1075
5	43 x 30	1290
4	43 x 38	1634
3.5	43 x 43	1849
3	43 x 50	2150
2.5	43 x 60	2580
2	43 x 75	3225
1.5	43 x 100	4300

43 cm is the standard width of most audio appliances. However other perimeter sizes are available provided they do not exceed the maximum area for the given thickness asked for.

Other dimensions are available on request.

STANDARD SIZE IS 430MM X 380MM X 40MM









Whole sale pricing:
Price for standard size $ 99.00 per slab lightly arrassed on one surface.
A minimum of 52 slabs of one size only.
Mixed sizes: $AUD 139.00 each but still 52 slabs a minimum.
The reason the Vesicular Basalt works so well as an isolation platform is because of the innumerable number of gas vesicles in the slab and the hardness of the rock matrix. These work to kill vibrations from transiting the slab and will also earth vibrations induced into the slab by the Mecado^TM.

This works well for electronic appliances and also for loudspeakers. this combination will offer the best isolation and deliver the maximum enjoyment.

What about Granite and Marble?
Both granite and marble are dense and heavy rocks. Their density being similar to the vesicular basalt. But  marble has no displaced discontinuities in its matrix though granite has innumerable discontinuities that meld into each other at their crystalline boundaries. Hence sound is reflected around inside the rocks and is not rapidly dissipated, though somewhat more so in granite than marble. Vibrational artefacts still make it through the rock and it is only by virtue of their heavy mass that they deliver any dampening at all. Vesicular basalt on the other hand being of similar mass and density, by virtue of its vesicular structure, dissipates an exceptional amount of vibrational energy at the vesicle / matrix interface, of which  within the rock matrix there are many thousands.
The difference is immediate and quite audible.

Allow up to 3 calendar months for shipment as the 52 minimum slab order is sent via surface only. Each slab weighs about 18Kg each. Hence each order weighs over one metric tonne.
