we think that an audio racks should have three basic features:

1 - great aesthetics and design.
2 - modularity.
3 - serious study to reduce low frequency vibration.

1 - First of all we studied an unusual shape: our brand will be identified by our design. We wanted an impact shape without penalizing useful sizes.
We studied carefully hi end market because we wanted to guarantee useful sizes and we create two racks with 500 x 500 mm useful sizes (Accordeon and Ghironda). These sizes accept over 97,5% of audio electronics in the world. For bigger amplifiers we create Bandura's line.
So after few months we have reached the current shape. Unique audio racks with no rectangular shape.
For a particular rack (Revo Audio Stand) we had help to an external designer (actually he works with Sonus Faber's team) and we use very special finishing.
All our suppliers works in nautical market to guarantee high standard quality and all our racks are totally made in Italy.
We use only original hand made polished Degussa-Rohn Plexiglas (guarantee ten years against yellowing) and only Finnish birch phenolic bonding.

2 - For us there is a great mission: our customers must remain with Bassocontinuo to all their life!
Actually in audio furniture market, there a lot of fixed racks. The big problem for the customer is: "When I change my amplifier, I've also to change my racks..."
with Bassocontinuo this is not a problem! When the customer needs more height between one shelf and the other, he can add some stainless steel spacer and increase this height (we propose 9 standard heights but with this system, the customer can create a lot of multiple height).
Furthermore, our racks can change structure. We always said that we've "chameleon racks".
For example if a customer buy Accordeon S and in future buy two hot vacuum tube amplifiers, with some simple operations and some spacer, he can transform his Accordeon S in Accordeon AA and place the hot amplifiers on side shelves.
Finally we propose over ten different finishing in three different materials to help every customer to introduce the rack in home design (the wife don't beat him :-) ).

3 - When we start to produce our racks, about two years ago, we spoke many times with some engineers of "antiseismic engineering unit" of an Italian university.
They say that the only success feature to fight low frequency vibration is introduce a serious decoupling between the floor and rack.
With their help, we introduce two systems to minimize floor-bone vibrations and breaks up standing-wave vibrations: the first is use an NBR Oring under each base puck and the second is to decoupling each shelves from stainless steel with a transparent washer.
All our racks (models Accordeon, Ghironda and Bandura) are totally decoupled from the floor.
We create a very rigid structure (all our legs are FULL, we don't use tubular with bolt) with great heavy, supported on gum decoupling: the concept is similar to antiseismic home (the foundation supported on great gum plate). The gum adsorb most of low frequency vibrations and transforms to heat.
To test this theory we make a lot of accelerometric measures and we noticed that the average of vibrations was killed before reach our shelves.
On the sound this means in more precision, more details and there is a great improvement of image focus.
We noticed that there are no significant differences from one shelf material and the oder. The only thing is that plexiglas is more heavy and he lowers further the resonance frequency of the rack.
