Design
The front of the housing is made of solid, acoustically decoupled aluminum in the colors silver, medium bronze or black. The interior of the elaborately stiffened body is always high-gloss lacquered and optionally available in macassar, light walnut or dark walnut. Alternatively, a white or black high-gloss finish is also available. The different colored fronts and housing surfaces can of course be individually combined with one another.
