When you have no space for bass, our Prime R2SD4-12 shallow subwoofer will satisfy your need. This 12” subwoofer handles 250 Watts RMS, and the 4-Ohm Dual Voice Coil design lets you wire them in various configurations. 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.
