Larger than the C10,
and therefore able to use a 200mm bass/midrange unit, the C20 showed many
similarities to its smaller brother, but with the greater cabinet volume
allowing increased bass capability and higher sensitivity.
The C20 was the
classic bookshelf speaker in size, performance and price, and showed just how
good the performance can be from a modest economical system.
The new
B200 bass/mid unit uses a polypropylene diaphragm to reduce colouration, while
a new high sensitivity, which in
combination with equalisation and computer optimisation gives a flat frequency
response with the modest bass and lower-midrange reinforcement provided by a
rear wall.
Attractive
modern design and a high standard of finish combine with finely balanced
performance, taking advantage of the latest technologies in design and
manufacture.
