Characteristics and sound properties

The SOLO 50 applies the SOLO 100 concept to a more compact cabinet. This makes the units suitable for smaller rooms where the larger version would be too physically overpowering or the bass too powerful.

With a net volume of 50 litres, it is essential to have an internal resonance absorber as with the SOLO 100 owing to the Q-factor of the B 200 6 Ohm. This can also be used to fine-tune the bass reflex. The lower limiting frequency is not as low as with the SOLO 100 but is certainly sufficient for small to medium-sized rooms. The absorber must be carefully damped again.

The correcting circuitry is designed by analogy to the SOLO 100. If you replace the 15 ohm resistance with a 22 ohm, the increase in high-frequency frequency response will be eliminated and the result as measured in the measuring room was a well-balanced spectrum. Listening tests showed, however, that, as a result of the beaming effect of this wide-range speaker, a slight increase is beneficial in most listening environments.

Extract from Klang & Ton 04/2004
"The B 200 broad-range driver made by VISATON demonstrates once again the incredible potential inherent in it. Even when combined with a woofer, all its positive characteristics remain unmitigated. In fact it's quite the contrary - they are even more precisely sculpted. Absolutely brilliant."

Extract from Image HiFi
This full-range speaker is so neatly integrated in the overall sound that it comes across as a presence in its own right, and yet a carefully blended one - like that of an additional tweeter injecting extra freshness and brightness into the picture, the final effect being one of totally holistic experience. It would, therefore, not be accurate to accuse the B 200 of being either too modest or reticent in the high-frequency range because this 20 cm speaker reaches well into the higher frequencies when aimed at the listener. It is not stingy with the details, and has sufficient output level, it is responsive, creates a stable sound field and carefully blends the finer details with the more energetic ranges.
This speaker can cope with volume, has good bass response, is an unbelievably homogeneous loudspeaker with powerful all-round capabilities and a musical talent all of its own. The Solitude is technically and from a sound point of view light-years away from the fluffy mush produced by so many boring three-way boxes.

CONSTRUCTION

We suggest two alternative cabinets:
1) simple cabinet with narrow chamfers on the sides
2) more sophisticated design with a ring round the B 200.
Acoustically, there is hardly likely to be any difference. The second alternative is much more complex to build, though.

The base is screwed onto a frame and not glued, to enable you to fit the bass reflex tube.

Inner damping

Four mats of damping material are arranged as shown (see drawing). The mat for the inner channel is cut to the width of the cabinet (22 cm) and pushed into the channel flat. The lower mat is rolled lengthways and wrapped around the bass reflex tube but leaving the opening free.
