R2SD4-12

When you have no space for bass, our R2 12" shallow subwoofer can help satisfy your need for low frequency music. These drivers can fit in tight spaces due to an elevated motor structure that reduces speaker depth. Mica injected polypropylene cones make sure bass notes are clean and accurate. Stamp-cast baskets feature spider venting typically reserved for traditional depth mounted models to keep the motor cool! These shallow subwoofers are optimized for sealed enclosures.
