Luxury high end HiFi loudspeaker cabinet made of UHPC concrete

During the development and production of UHPC
material for a special machine foundation, the
extremely good damping qualities of UHPC were
discussed.
This feature is also highly appreciated by developers
and producers of high end Hi-Fi speakers.

We sat down with some of these sound aesthetes
and talked about the use of UHPC concrete in the
speaker cabinet. The discussion ended with the fact
that we started the next day with the development
of an optimal UHPC concrete for high-end 
loudspeaker cabinets.

The first achieved damping values ​​were measured
with 0.027. UHPC concrete has a high density
(up to 2900 kg/m3). The water / cement value is
sometimes less than 0.2.
The compressive strength can be chosen between 
140 and 240 MPa. The modulus of elasticity is
for the most of our UHPC products 70-80 GPa.
With UHPC Cast Binder you can cast extremely 
accurate. Only the quality of the form here limits.
With UHPC Cast we were able to offer the Hi-Fi 
and housing designer the possibility to choose any
structure and geometry. In addition, UHPC concrete
loudspeaker cabinets are shockproof and waterproof.

The UHPC showed in tests as far as we heard have
no resonance. We hope for more interests, because this
work was a lot of fun for us.

As we have heard, some Hi-Fi enthusiasts have now
made the first vinyl player for venyl records from
UHPC and are thrilled with the end results in design
and in the audio / sound result.
