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.
