FS: Alpine Type-R 12" Subwoofer + box
Selling USED Alpine Type-R 12” Subwoofer (SWR-1221D) enclosed in a 1.0ft^3 carpeted MDF box. The rubber shows a little bit of wear and just under "R" there is a very very small depression, barely noticeable. The sub still plays perfectly though. Besides being a little bit dirty, see pics, the sub definitely gets the job done and it sounds great for all types of music: rap, rock, punk, techno, jazz, you name it. in the sealed 1.0ft^3 box the bass is tight and punchy for rock style music, yet can still boom for your rap tracks.
