Alpine SWR-1243D

These redesigned, fourth-generation Type-R subwoofers include several enhanced features to achieve even cleaner, deeper bass extension, faster, more accurate transients and even greater output capability than before.

The Type-R Subs have been completely redesigned to offer more installation flexibility and application versatility to build the ideal sound system.The  new designs offer a near 20% reduction in mounting depth, while offering even greater output capability.

The new FEA-Optomized Motor Structure together with Alpine's revolutionary High-Amplitude Multi Roll (HAMR) Suspension Design gives the new Type-R Subwoofers the highest X-max and SPL output in the category.

With a real-world, measured 21mm of X-max, allow the new Type-R Subwoofers to deliver the best-in-class bass output, ultra-low distortion, and unparalleled sound quality.
