For ultimate performance, the K1 floor-standing
model offers a similar performance to the B1 but with the potential
for increased level and detail through the use of four low frequency
drivers in conjunction with mid and high units in a 3 & 1/2 way
system.
K1 employs a single D50 mid range driver (patent pending), between
900Hz and 4 kHz with the range beyond being handled by a D26 tweeter
(patent pending). Below 900Hz the K1 uses four C125 mid-bass drivers
(patent pending), two mounted on the front baffle and two mounted on
the rear baffle of the cabinet. These four drivers are internally coupled
in pairs via screw tensioning units for reaction cancelling. All drivers
receive the same signal at frequencies below 100Hz while above this
point the drive to the rear is progressively attenuated leaving only
the front upper driver to operate all the way to 900Hz to ensure good
vertical dispersion at crossover. Fourth order filters ensure phase
coherence through both main crossover points resulting in a seamless
and symmetrical polar performance.
Integral to the K1 enclosure is the stand. Made from the same cast
carbon fibre reinforced polyester compound as the enclosure, the stand
provides an exceptionally stable footing further guaranteed by the
use of a total of five custom spikes mounted around the periphery of
the base. Adjustment of the two rear spikes and that at the front sets
the correct attitude while the remaining two can then be brought into
contact with the floor for maximum safety.
Within each of the streamlined arms are hidden
separate conduits to guide the Van den Hul® interconnecting cable away from the two
internally mounted crossovers into the base. Precision machined WBT® gold
plated terminals are discretely located at the rear of the base to
allow a visually unobtrusive connection to the outside world.
