The Kensai is a fine
example of British design flair, where every aspect contributes to making
it one of the best sounding super-babies on the market. Uniquely, it manages
to combine the incredible clarity and speed of a ribbon tweeter with a
coherence of sound normally found only in single driver systems. It does
this by combining an exceptionally high performance woofer with a special
ribbon tweeter that allows for a lower crossover point than any other,
whilst maintaining minimal distortion.
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 frequency dispersion.
The woofer is a state
of the art light weight magnesium coned design costing many times that
used in most high-end speakers. The motor uses copper Faraday rings to
improve linearity and give the clearest, least fatiguing sound. A solid
copper phase plug quickly removes heat from the voice coil for crisp,
uncompressed dynamics. Combined with 9mm peak coil travel, the little
Kensai woofer also possesses impressively deep, controlled bass.
The cabinet is made
by bespoke furniture manufactures in Kent, England. It uses a method of
bracing where the energy in one side panel is fed to the out-of-phase
energy in the other, so resonances cancel each other out. The centre section
is made using light weight material in small sections for maximum rigidity,
keeping resonance within a narrow band, so the sound is incredibly free
from box colouration.
The porting system is a rather uncommon aperiodicity
damped Helmholtz slot resonator. This allows the speaker to produce surprisingly
deep and pacey bass, while also reducing the woofer's work load below
a sensible frequency to maintain low distortion and good dynamics.
The crossover is carefully
phase aligned, and all aspects such as dispersion, power handling and
resonances are considered to create as seamless a sound as possible. It
uses low resistance ferrite and air-core inductors, polypropylene film
capacitors, and wire wound resistors to ensure all the musical information
is transferred to the drivers...and maximum enjoyment delivered to the
