25 mm (1") fabric dome driver for the high-frequency range above 2000 Hz. Due to the optimised dome shape with double coating in conjunction with the highly damped surround, linear frequency response has been made possible. Due to the powerful magnetic driver and the ferrofluid-cooled voice-coil high efficiency and high power handling can be guaranteed.

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.

This designer speaker cabinet is a challenge for any experienced craftsman who is looking for a speaker that stands out from the crowd. The excellent design means that the shape is not just a designer's whim but a technically thought-out reality. The front baffle has been kept as narrow as possible all the way along. This projects the sound away from the speakers into the room, in such a way that the instruments and voices are perfectly positioned and - provided the speakers are positioned away from the walls - the listener is treated to excellent spatial sound. The curved shape of the side panels has a stiffening effect and reduces resonance dramatically. In this way, the conventional reinforcements are not required.
In the bass department, we have the GF 200 - 2 x 4 Ohm with its high level accuracy, which can really make the most of its long-stroke voice coil and fibre-glass reinforced cone. The bass driver is positioned very close to the floor of the cabinet, and requires a low cross-over frequencyup to the mid-range. In order to maintain the excellent level accuracy here, a speaker with a large cone surface area has been chosen. In this combination, the AL 170 - 8 Ohm demonstrates its remarkable mid-range characteristics that guarantee exceptional transparency and clarity of sound. The tried-and-tested G 25 FFL - 8 Ohm textile dome unit adds depth and vitality to the high-range.

The EXPERIENCE V 20 is a 96 litre vented cabinet and features a bafflearrangement based on the D'Appolito principle arranged symmetrically around the tweeter. In order to suppress any unwanted interference by the front baffle on the radiation pattern, the entire mid- to high-range unit is not positioned in the middle of the cabinet, but towards the inner side.
The woofers in the EXPERIENCE V 20 are two W 200 S - 8 Ohm 's in parallel up to around 450 Hz. From here, the mid-bass unit takes over. The W 130 S - 8 Ohm 's, also connected in parallel, cover the mid-range frequencies up to around 3000 Hz and hand over to the G 25 FFL - 8 Ohm textile dome unit at the high-range.
The crossover unit is designed for bi-wiring.
The very first impression you get of this V 20 speaker system will demonstrate the unrestricted exuberance the speakers are capable of. At the lower octave levels, the two 20 cm woofers produce crisp bass sounds with a dynamic punch that is unusual for speakers of this size. The mid-range produces absolutely linear, undistorted sound and the overall effect is of tangible sounds, spatially separated from the speakers themselves. The crystal clear, airy high-range reproduction from the 25 mm textile dome unit puts the final touch to the upper frequency end.
The VIB 170 AL is a slim-line 2-band column speaker using an AL 170 - 8 Ohm woofer and a 25 mm, G 25 FFL - 8 Ohm textile dome tweeter. The 34 litre bass reflex cabinet produces a remarkably deep lower limiting frequency of only 25 Hz, but maintains its powerful, precise bass reproduction. The reason for this is the subwoofer AL 170 - 8 Ohm with its rear-vented spider and its long cone strokes. The flow-optimised bass reflex tube BR 25.50 is mounted at the rear of the cabinet to present the most ideal optical appearance, but can, if the cabinets are to be set close to a wall (closer than 10 cm), be moved to the front without any loss in quality.
The two 1 µF capacitors in conjunction with the 2.2 mH coil form a blocking circuit that effectively suppresses the resonance in the aluminium diaphragm generated typically by that material.
The VIB 170 AL is a compact speaker with well-balanced sound quality and clean-cut bass and impulse fidelity, providing excellent dynamic properties for a speaker of this size.
The VIB 2000 GF is the logical development of one of the most popular column cabinets in the field of D.I.Y. speakers - the VISATON VIB. The concept of the 2-way enclosure in a 45 litre vented cabinet has been retained, but the drivers used are different, and the crossover unit has been reappraised to suit. In the low- to mid-range we have the GF 200 - 2 x 4 Ohm, whose fibre glass cone can produce a big stroke and thus is good for powerful low-range bass even at higher volume levels. The parallel resonant circuit before the low pass unit compensates for the rise in the mid-range of the 200 mm cone drive and guarantees a linear and coloration-free frequency response until the tweeter takes over at around 2.5 KHz. The 18 dB high-pass section links in the 25 mm G 25 FFL - 8 Ohm textile dome unit.
The VIB 2000 GF produces remarkably vivid, precise bass output at the lowest frequencies, linear mid-range sound, spatially separated from the speakers themselves and a smooth, finely sketched high-frequency range.
15 x 22 cm Waveguide of high-quality plastic for 25 mm tweeters. The exponential enlargement provides a high sound pressure level gain in the lower high frequency range, which discharges the tweeter. In addition, the focus and the coupling to a woofer are improved, because the sound generation planes move closer together.This Waveguide was adjusted in width and length to 13 cm (e.g., AL 130 8 Ohm) and 20 cm (e.g., AL 200 8 Ohm) loudspeakers.For the connection of the tweeter 4 pieces M4 screws (length approx. 10 mm) are added.This waveguide is suitable for: G 25 FFL 8 Ohm; KE 25 SC 8 Ohm; DSM 25 R 8 OhmPacking unit: 1 pc.
The naming of the Studio 1 was very easy due to the optics, which are reminiscent of typical studio monitors. This does not mean that the Studio 1 is solely a studio monitor. This speaker can also be used in larger home theater systems and, of course, as a pure stereo system, supported by a powered subwoofer if necessary.
By using the Waveguide WG 220x150, coupled with the excellent properties of the well known G 25 FFL - 8 Ohm tweeter, and the two AL 130 - 8 Ohm woofers, an interesting and extraordinary construction speaker kit came into being, which can be described as extremely rich in detail and lifelike in terms of precise focus and soundstage.
During the development of the STUDIO 1, some tricks had to be employed to achieve the above mentioned properties. The bassreflex port is installed at an angle of 45° upwards, which eliminates the well known problem of standing waves in the channel itself.
Additionally, the Waveguide WG 220x150 adds substantial improvements to the qualities of the G 25 FFL - 8 Ohm: On the one hand, the height of the waveguide brings the sound generation zone of the tweeter and the woofers into line, as on the other hand the exponentially expanding shape of the waveguide optimizes the radiation pattern and puts less strain on the tweeter in the lower frequency range. An optimized radiation pattern in this context means that the width of the acoustical beam of the tweeter is adapted to the beamwidth of the woofers in the region of the transition. Thereby, a homogeneous sound also arises in rooms with unequal reverberation times.
These important points allow for the excellent sound of the Studio 1, which can be described in summary by the word "directly".
