C1 is a three-way system employing a single D50 mid range driver, between 900Hz and 4 kHz with the range beyond being handled by a D26 tweeter. Below 900Hz the C1 uses two C125 midbass drivers mounted on either side of the central mid and high domes. The two drivers are identically driven in order to preserve a symmetrical horizontal polar pattern at all frequencies.

Fourth order filters ensure phase coherence through both crossover points resulting in a seamless response. Optionally, the C1 may be mounted on its matched stand. Made from the same carbon fibre loaded polyester compound as the enclosure, it provides an exceptionally stable footing while holding the loudspeaker at a gentle angle to suit most floor mounted situations.

To further guarantee the stability of the complete system, a total of five custom spikes are mounted around the periphery of the base. Precision machined and gold plated binding posts are recessed into the rear of the cabinet and linked internally to the crossover boards using Van den Hul® cable throughout.
