The CT CENTER 81 is a compact, enclosed 3-way system with well-balanced sound quality and complete magnetic shielding, as required for example if positioned close to a TV or PC. Inside the cabinet, we use magnetically shielded speakers, types F 8 SC - 8 Ohm (8 cm full-range) and SC 5 - 8 Ohm (10 mm tweeter) and the complete speaker then meets the shielding requirements of the THX® regulations (3-Gaussian curve). The asymmetric design of the front baffle and of the crossover unit provide good omnidirectional sound distribution both vertically and horizontally. It is possible to install the speakers in the upright position, as is usual for multimedia systems, or lying down on top of a TV, as is usual with surround systems.

In terms of sound quality, the CT CENTER 81 produces clear-cut sound, well removed from the speakers, but with remarkably well-formed bass reproduction for a system of this size.


NANO is the name of the latest miniature magic made by VISATON. This system, equipped with the tiniest of satellite speakers, sounds as uncompromisingly good as many far larger upright systems. The high frequency range is designed as a dipole and, in conjunction with the mid- and bass frequencies, creates a well-rounded, airy overall sound. The balanced frequency response across the entire frequency range, one hitherto not achievable by this kind of system, is a feature of the Nano system.

The tiny satellites must be considered "sitting room friendly" because they are so compact, they'll fit in any shelving system. The subwoofer cabinet, equipped with the well-known high-end GF 200 driver, has been designed to match the satellites and simply disappears in a corner of the room.

The BR 25.50 bass reflex tube with its flow-optimised, curved trumpet vent, contributes to the good overall sound. The subwoofer cannot be located due to its 18 dB filter and separation at 150 Hz. A high-pass system and reflex balance enable the two tiny, magnetically screen satellites to produce remarkably dynamic sound. They can, therefore, also be used as centre or surround speakers for Dolby Surround systems at home.
Not available as a complete kit.


NANO, Visaton's magic baby, has been revamped. In this new version, the rear-mounted tweeter has been dispensed with and the crossover unit adapted accordingly. This has enabled improvements in the natural quality of voice reproduction. In addition, the NANO is now far less susceptible to changes in position, especially the distance between the speakers and the wall. It is now possible to integrate them without loss of quality in bookshelves.

If you combine the NANO SAT MK II with the NANO SUB PR, you get a speaker system that is totally living-room friendly consisting of tiny satellites and a compact subwoofer which, all-in-all, sounds like a far larger, uncompromising column speaker set-up.

VOX 80

This the smallest member of the VOX family is an exactly scaled-down version of the larger models. The dimensions of the VOX 253 have been reduced by a factor of around 3. The driver concept, consisting of two mid-range loudspeakers and a side-mounted woofer, corresponds to the other VOX versions. The two 5 cm full-range FRWS 5 R - 8 Ohmspeakers fit perfectly in the baffle and cover mid-range. The smaller CP 13 - 4 Ohm tweeter ensures that the higher-frequency, although already well covered by the FRWS 5 R - 8 Ohm, is further strengthened. The woofer in this set is an F 8 SC - 8 Ohm full-range loudspeaker.

In order to be worthy of the honour of being included in the VOX family, the VOX 80 is fitted with a crossover which is just as conscientiously matched to the drivers as those in the larger models.

The results can be both seen and heard. The VOX 80 is an eye-catcher as well as an ear-catcher on any desk as a PC-based hifi, for example.

The VOX 80 has a power handling of 20/30 watts. In practice, in a PC environment, however, this output level is seldom, if ever, required. Set to an output of one watt, one VOX 80 will generate approx. 80 dB in a workplace, both speakers together create 86 dB. This is very loud. A miniature amplifier like the Visaton AMP 2.2 or AMP 2.2 LN will, therefore, be perfectly sufficient for most applications.
