Extreme bass fits in more places

The Type-R Subs have been completely redesigned again to offer more installation flexibility and application versatility to build the ideal sound system. At 4-1/2" for the 8", 5 - 7/8” for the 10”, and 6 - 3/8” for the 12”, these new designs offer a near 20% reduction in mounting depth, while offering even greater output capability.
