Characteristics and sound properties
As the name CLASSIC 200 suggests, this speaker design uses the classic 3-band
arrangement: one woofer, one mid-range cone and one dome tweeter, all arranged
one above the other close together in the front baffle. The AL 200 8 Ohm, TI 100
8 Ohm and KE 25 SC 8 Ohm used here are the best drivers in their respective
categories available from the VISATON catalogue. For an upright cabinet, this is
relatively small, enabling space-saving use in almost any sitting room.
The sensitivity of the CLASSIC 200 is excellent for a speaker of this size.
This is made possible by the "slim-line" bass tuning. In comparison with the VOX
200, which has almost the same driver arrangement, the lower limiting frequency
has been set slightly higher. This will appeal in particular to those who
appreciate more "crisp" bass reproduction. The difference is that, in the
CLASSIC 200, the low-frequency room resonance which is almost always present in
any room, is not excited to the same degree and this reduces the
reverberation.
The other drivers are also without doubt excellent and contribute to a
holistic overall sound consisting of precise mid-range and clear as crystal,
unobtrusive, smooth-as-silk treble frequencies.
Extract from Klang & Ton 05/2005
As one would expect, the Classic 200 produces a very fine sound image across
the entire range and this enables one to distinguish fine differences which are
simply inaudible with other loudspeakers. At the same time, one is never made to
feel that the speaker is trying to force this frank approach on one in an
obtrusive manner or invent things which were never there in the original
recording. In the low-frequency range, too, the overall sound quality remains
clear and well-balanced thanks to the fine tuning.
We, who always prefer
lively loudspeakers with verve and dynamism, could not fault Visaton's Classic
200, loved every aspect of them - they provided unqualified listening
enjoyment.

CONSTRUCTION
The cabinet sections are cut in accordance
with the parts list and glued together. Next, the openings and recesses for the
loudspeakers and the bass reflex tube (front panel) and terminal connections
(rear panel) are cut out.
Inner damping
Half a mat of damping material is pushed into the mid-range enclosure. The
rest is distributed uniformly in the cabinet, while ensuring that the port of
the bass reflex tube is left unblocked.
