Characteristics and sound properties

The first thing one notices about the CASABLANCA III cabinet is its striking design. This cabinet shape, however, has more than just eye-catching qualities, its acoustic qualities have to be heard to be believed.
The speaker consists of a large lower chamber and a top-mounted upper chamber and the two are interconnected through an opening that has been exactly calculated. This is, in fact, a twin-chamber vented cabinet. As a result of the twin-chamber arrangement, it is possible, in comparison with a conventional vented cabinet, to extend the range downwards by a considerable amount. The Helmholtz resonance of the upper chamber is around 90 Hz, that of the lower chamber around 33 Hz.
The fibre glass high-end GF 200 - 2 x 4 Ohm woofer has been used in the CASABLANCA III and helps achieve unbelievably low-range bass levels and, at the same time, producing remarkable maximum volume levels for a speaker of this size. The two tried-and-tested "softening" textile dome units G 50 FFL - 8 Ohm and G 25 FFL - 8 Ohm guarantee transparent, rounded sound qualities across the entire mid- and high-range. The convex cones also blend in well with the overall design of the CASABLANCA III model. The result is an unusual speaker both as regards its design and its construction principles with excellent low-range bass reproduction coupled with tremendous signal fidelity.
