The Kensai MKII is
a progression of the highly regarded original handmade Kensai 'super-baby'.
Combining the same superb isoplanar ribbon tweeter with a new woofer
system, crossover and cabinet, the Kensai MII delivers clarity and
coherence to a degree rarely heard.
The ribbon tweeter
uses isoplanar technology which allows push-pull drive of the
diaphragm in a similar way that an electrostatic speakers works,
producing exceptionally low distortion, and unrivalled top-end
clarity. It has a very large area compared with other ribbons, so a
low crossover point can be used, allowing the sound from the woofer
and ribbon to glue together far better than a standard design.
Finally, it also incorporates an acoustic lens to widen high
The woofer is a
state of the art, natural paper-pulp cone powered by an advanced
neodymium motor. This new 4" woofer provides additional
over the original Kensai, meaning a 20% lower power requirement for
the same sound level. Copper faraday-rings reduce distortion and the
basket is streamlined to cause fewer reflections. High frequency
cone break-up is also considerably reduced, meaning the sound stays
clean even when pushed.
The crossover, as
in the original Kensai, is phase aligned and utilises high quality
components. The crossover frequency has been lowered from 2.2KHz to
1.9KHz further improving driver integration and dispersion. The new
network also provides a more gentle and linear impedance load to the
amplifier, helping to make the Kensai MKII suitable for valve amps
with >20 watts.
The Cabinet has
undergone extensive redesign. Following BBC research the side panels
are now made from Birch plywood with sorbothane damping. This
material combination has faster energy decay than any other typical
material, including solid timber. The entire structure was then
analyzed with an accelerometer to map the modal patterns and
extensive internal bracing placed to minimize unwanted resonance.
Finally, the construction is angled backwards to provide physical
Made by hand in England,
the Kensai MKII is a product of true craftsmanship. Every aspect is
carefully considered from the assembly of crossover electronics to
cabinet joinery. Each pair is built by designer himself from start
