The K1 floor-standing model is the largest of the range which employs the coupled front and back bass driver system and integral stand.
The K1 employs a single D50 mid range driver (patent pending) between 900Hz and 4kHz 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 wo mounted on the rear baffle of the cabinet. These four drivers are internally coupled in pairs via screw tension units for reaction canceling.
Through the use of innovative crossover circuitry, all drivers receive the same signal at frequencies below 100Hz while frequencies above this point are delivered to the lower and rear drivers and are progressively attenuated leaving only the front upper driver to operate all the way to 900Hz, ensuring 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 fiber reinforced polyester compound as the enclosure, the stand provides an exceptionally stable footing further guaranteed by the use of a total of five 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 Von 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.
