Key Features

2250w 12" Dual 4Ω Voice Coil Subwoofer - Alpine Car Audio Systems R-W12D4

Type-R Subwoofers have been known for their power handling, clean output and deep bass excursion at a mid-line price. The R-Series Subwoofers feature a Kevlar-treated cone for durability. The combination of this cone with the Santoprene surround allows the Subwoofer to deliver 19mm of X-max, for incredible, hard-hitting bass. A new method of attaching the spider and cone to the voice coil ensures not only rigidity throughout the motor structure but contributes to the Subwoofers increased accuracy.

Not as good as the Old R Type
Josh on 16/04/2021 1 star rating

I have had R Types for over 10 years and recenlty replaced my old SWR1224D with this R-W12D4 and running on the same PDX Amp and same bass box teh Sub BLEW. I sent Back to CAC and Alpien said its not uynder warranty, after doing alot of research I am not the only customer who this has happened to, people beleve the copper coil is not of teh same quality and burns out easy. Car Audio Centre have been grrat and replaced the Sub with a DB Audio Trex12 what sound alot better than the Alpine.
