10 cm (4") HiFi low-midrange driver with coated paper cone, elastic rubbersurround and 20 mm voice-coil. Suitable as woofer in mini-speaker systems and due to the very balanced frequency response especially suitable as low-midrange driver in 3-way speakers and in subwoofer/satellite systems.

The ARIA 2 LIGHT is a small-sized 2-band shelf-top speaker system that uses two W 100 S - 8 OHM mid-bass units and one G 20 SC - 8 OHMdome tweeter. In smaller rooms and if used as a shelf-mounted unit, the system has a considerable bass foundation which means that a separate subwoofer is not required. However, if coupled with a good powered subwoofer, the range of tonality of far larger hi-fi speakers is achieved.
The larger cabinet and the D'Appolito arrangement in the ARIA 2 LIGHTprovide a far greater maximum sound pressure in comparison with the smaller ARIA LIGHT.

The STARLET is a 3-way speaker which is extremely good value for money. The individual drivers used here have all proved their worth in numerous well-known constructions.
At the bottom end of the frequency range, there is the W 200 S - 8 Ohmfrom the EXPERIENCE V 20, mounted in a 58 litre vented cabinet. The mid- to high-range is covered by the W 100 S - 8 Ohm and DT 94 - 8 Ohm from the ALTO series of speakers.
The impression given by the STARLET is of a solid low-frequency foundation with powerful, crisp bass. The mid-range has a pleasant, unobtrusive sound, and at the higher frequency ranges the STARLETproduces sparkling, clear-cut treble. In a nutshell, the STARLET is an extremely reasonably priced column speaker with a well-rounded tonal character and good power handling capabilities.
Soon after its launch, the VOX 200 became one of the most popular and successful high-end kits. Several excellent tests in numerous specialist magazines have demonstrated that this system is at a quality level normally expected of far more expensive candidates. We were asked whether it was possible to fit these cabinets with much cheaper loudspeakers and still get good results.
At the lower frequency end, we replaced the AL 200 - 8 OHM with the W 200 S - 8 OHM and also took out the TI 100 - 8 OHM mid-range loudspeaker, replacing it with two W 100 S - 8 OHM. We left the G 20 SC - 8 OHM dome tweeter unchanged. Initial tests showed that only a slight adjustment to the crossover were required. In terms of sound quality, the modified VOX put up an excellent showing in comparisons with the original.
Tabula is a stereo loudspeaker cabinet designed to look like a shelf that is extremely versatile. It can be used as a bookshelf, TV stand, worktop or hifi rack and integrated invisibly into the room as a loudspeaker.
The main drivers are the miniature fullrange BF 32 - 8 Ohm speakers which, despite their modest size, sound remarkably grown-up and incorporate such technical details as aluminium diaphragms and neodymium magnets.
The bass department of the Tabula system is provided by the W 100 S - 8 Ohm, an excellent value-for-money bass driver that has been popular for decades for that very reason. In the correspondingly designed bass reflexcabinet, this driver generates excellent low-frequency bass that is remarkably firm despite the size of the speaker.
The combination of these three components, coupled with a sophisticated crossover and the design of the system details produces a powerful stereo sound system which can be invisibly integrated into the room. Supplemented with a miniature amp (such as the VISATON AMP 2.2) and a simple MP3 player, the Tabula becomes a full-scale Hifi system.
