CASABLANCA MK IV

Art. No. 5979
Characteristics and sound properties

The first thing one notices about the CASABLANCA IV 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 bass reflexcabinet. As a result of the twin-chamber arrangement, it is possible, in comparison with a conventional bass reflex 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 woofer in the CASABLANCA IV is the AL 200 - 8 OHM, which is so popular among connoisseurs of high-end technology. Thanks to its long-stroke woofer, the AL 200 - 8 OHM helps the CASABLANCA IV achieve unbelievably low-range bass levels and, at the same time, producing remarkable maximum volume levels for a speaker of this size. Another "first" in this model is the two tried-and-tested DSM 50 FFL - 8 OHM and DSM 25 FFL - 8 OHM titanium dome units, that guarantee transparent, rounded sound qualities across the entire mid- and high-range.

Results: 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.
