13 cm (5") HiFi low-midrange driver with coated paper cone, elastic rubber surround and 25 mm voice-coil. Suitable as woofer and due to the very balanced frequency response also as low-midrange driver especially in large 3-way speaker systems.

Just because your sitting-room isn't large enough for big speakers, doesn't mean you have to do without high-quality sound. The VISATON subwoofer satellite system, ALTO Genesis, provides excellent listening pleasure in a very small space.
Separating the subwoofer into two cabinets - left and right channels - means that the assignment to the corresponding satellite speaker is hidden. On the other hand, the two subwoofers can also be placed together as mono subwoofers. The bandpass subwoofer cabinet contains the 13 cm long-stroke woofer W 130 S - 8 Ohm. The well-balanced driver, cabinet and frequency parameters enable the subwoofer to be separated off at 110 Hz with a slope rate of 30 dB/octave. That is a level seldom achieved even by active subwoofers. The satellite speakers are also steeply cut off towards the bottom end by means of an optimised crossover unit. This optimised coupling technique means the position of the subwoofer is in reality not determinable.
The small shelf-mounted satellite speakers produce the lively high frequencies and a balanced mid-range and provide the overall spatial qualities required. The tuning frequency cuts in at 110 Hz.
The COUPLET LIGHT is a compact D Appolito configuration shelf speaker. It can be used as a shelf-top speaker or mounted on free-standing supports. In contrast to the original COUPLET, this system uses two W 130 S - 8 OHM as woofers. The tweeter and the cabinet design with its flow-optimised BR 25.50 bass reflex tube have been taken over unchanged.
The result is a speaker that maintains its linear characteristics right across the frequency range. Due to the well balanced medium range, the fine details of music reproduction, in particular, comes across particularly clearly. The excellent omnidirectional sound distribution creates a particularly room-filling music reproduction and clear location of each individual instrument or voice. The lowest-range bass comes across equally powerfully. In short, the COUPLET LIGHT is a speaker that is really good fun.
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.
Just as the light versions of VOX and COUPLET, the QUINTETT LIGHTis aimed at coming as close as possible to the outstanding sound quality of its "big sister", with substantial lower priced driver units.
When listening to both the QUINTETT and the QUINTETT LIGHT, the direct comparison attests: Goal reached.
The QUINTETT LIGHT is, as well as the QUINTETT, a high efficiencyspeaker with a very balanced frequency response. Only in terms of dynamics and maximum sound pressure level, the QUINTETT LIGHTcannot fully keep up with the outstanding performance of the QUINTETT.
Anybody who is into the concept of the QUINTETT, but at a more favourable price, is well advised to take a closer look at the QUINTETT LIGHT.
The ALTO LINE MK II is a slim, 2-band column speaker with two 13 cm mid-bass units and one dome tweeter.
Due to its slim design and the correspondingly small footprint, this model is ideal as a free-standing speaker in smaller rooms.
The spatial separation is well handled by the speakers and can, as a result, produce clear sound characteristics even in "normal" living rooms.
The unusually broad range bass spectrum for a speaker of this size, that remains crisp even at higher output levels, is a point worthy of note.
As a result of its balanced, crisp sound characteristics, and the finely detailed, exuberant high-frequency output, the ALTO LINE MK II can be considered a fully-fledged member of the ALTO speaker family.
