Each little bass-engine is generously specified with custom installation in mind, providing versatile input and control options including RS232 and a dedicated ‘SubConnect’ PC applet via a wired USB interface.

The compact rigid 18 mm MDF cubic cabinets with regular 25.5 cm dimensions incorporate no fewer than three robust, similarly sized 8" C-CAM drivers. Each system array comprises an active high-excursion drive unit powered and trimmed by potent DSP-tuned amplification, together with twin side-mounted ABRs (Auxiliary Bass Radiators).
