The Belong range is a study in material science. 

 

 DuPont ™ Corian® is a polyacrylic & bauxite ore compound. It is a popular surface material for high-end kitchens and bathrooms and has been since the 1970s. 

Why has Chario chosen it for its cabinets?

Because it has a very high isotropic value.

A loudspeaker cabinet must look good and withstand high pressure variations without leakage.

 

Concrete - 2,400 kg/m3 density figure.

DuPont ™ Corian® has 1,700 kg/m3 density is very tactile and beautiful, furthermore it spreads vibrational energy equally in all directions at high longitudinal wave speeds, i.e isotropy.

Wood 300 kg/m3  -700 kg/m3 (orthotropic)

When air impulses are raised inside a Corian® cabinet from loudspeaker drivers, it reaches all internal surfaces instantly  (the air density variation of low frequencies are produced as a pressure field without waves). The structure  inflates (or deflates) as a whole, like a balloon. 

Why not use a balloon?

A balloon is thin, light and less elastic (steel possesses greater elasticity than rubber!) it  expands and contracts easilly. It is a poor material for loudspeaker use because unwanted energy (expansion/contraction) is transferred back to the drive-units.

DuPont ™ Corian® on the other hand is thicker, heavier and more elastic ( high Young's Modulus) so its inertia acts against the moving air. Furthermore  due to it's isotropy properties, longitudinal high speed waves occur at the same time as  transient waves, ( see Newton Law). This gifts the loudspeaker twice: 

1. No pressure leakage: increased driver control

2. No vibration losses: no transient interference.
