DMD104SH - 10" 4Ω Shallow Subwoofer  

Look no further if you are seeking a solution when challenged with space limitations for adding bass to your car audio system. The Diamond DMD shallow series subwoofers measure in with only 3 inches of depth and perform best in sealed enclosures performing just like a conventional full-size subwoofer but taking up less space. For optimum bass response, we recommend using two DMD shallow subwoofers in a narrow 1 cubic foot enclosure. Extremely shallow mounting depth of 3 inches.
