Horizontally opposed 13” drivers are arranged in a force-cancelling configuration, each driven by its own independent power amplifier. Rather than using electronic equalization to extend low-frequencies it is instead employing to compensate for non-linearities and variations in the drivers themselves, perfectly matching their outputs, minimizing the energy they feed back into the cabinet. The enclosure itself is a curved wall composite construction that is carefully tuned, using Comsol modelling software, to absorb and dissipate the drivers’ unwanted mechanical output before it can accumulate and feed back into the acoustic output, blurring and distorting timing, pitch and textural information.

Consider for a moment the importance (and cost) of a high-quality line-stage to system performance. How many of the active crossovers used by conventional sub-woofers match that level of performance? But that’s exactly what they should do if they are going to successfully integrate their bass output with the rest of the system. That’s why the Subissimo uses a passive crossover at its input, as well as setting its drivers high in the cabinet walls, away from unwanted room reflections and reinforcement that risk smearing and colouring the low-frequency output. The result is a low-colouration sub-bass system of unmatched neutrality that can be seamlessly integrated with any high-quality speaker system, setting new standards in low-frequency reproduction.
