When you have no space for bass, our PRIME R2S 10" shallow loaded enclosure is sure to be a perfect fit for your ride and your budget. These shallow loaded enclosures can fit in tight spaces due to the slim-line depth of 3.25" on the top and 5.25" on the bottom. The wedge design is optimized for single-cab trucks with limited seat travel. Are you ready to rock out? Yeah, we thought so.
