The 3100 series 12 employs a finely-tuned balance of damping and extensive motor force to achieve very high efficiency, offering exceptional versatility and unmatched performance in a variety of real-world functions:

Paired with a traditional (4th order) bass-reflex enclosure, the subwoofer’s output can be focused along a narrow bandwidth for use in extreme loudness / SPL applications. In a 6th order bass-reflex, the output can be spread along a wider frequency range, shifting emphasis onto sound quality with articulate delivery and highly controlled excursion.

The above designs have been engineered for a “two tier” balance of compatibility: First, between the cabin acoustics of a sedan, hatchback and an SUV, and second, between the two available voice coil configurations, for a total of six balance points. This ensures a linear response and optimal power handling for listening purposes under most circumstances. Please visit our Enclosure Design Service page for custom designs.
