G 50 FFL - 8 Ohm

Art. No. 1176

50 mm (2") High-End fabric dome driver for the midrange band between 800 and 7000 Hz. Due to the optimised dome shape with damping coating in conjunction with the highly damped surround, linear frequency response and no partial oscillations. Due to the powerful magnetic drive and the ferrofluid-cooled voice-coil high efficiency and high power handling can be guaranteed.

*Gross price for private customers. Industrial prices are available on request.

CASABLANCA III

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.

SYMPHONIE

SYMPHONIE's sound profile can best be described as very mellow and melodious. The two AL 170 - 8 Ohm 17-cm woofers generate a full-bodied but well-defined bass in their isolated bass reflex compartments that one would not normally expect of a design such as this. Even at the lowest bass frequencies, SYMPHONIE retains its fidelity and produces clear, precise sound even at high volumes.

The highlight of the SYMPHONIE system is the 50-mm G 50 FFL - 8 Ohmmid-range dome. In the mid-range, it is this driver that ensures unbelievably tangible reproduction of the stage arrangement and provides clearer detection of the central (vocalist's) position than that provided by many other systems. Even recordings that are not perfectly spatial come across as well separated from the speakers, thanks to the SYMPHONIE. As a result, longer listening sessions become a source of relaxed long-term pleasure.

In the high-frequency range, the well-known ceramic dome driver, the KE 25 SC - 8 Ohm, is used to good effect and rounds off the overall soundpicture with its silky-smooth sound properties and outstanding linearity.
