The starting point of Diamond Audio's subwoofer line. The Diamond DMD series has taken a giant step in high performance while still having attainable price points for those on a budget. Performance improvements have been achieved through constant R&D and for DMD series, this includes the incorporation of chemically treated voice coils and cross-flow design basket frames for greater thermal heat dissipation. The use of an even higher-density NBR half-roll surround to maintain greater linear performance provides more value to DMD series. A Klippel® DA optimized motor and suspension symmetry certifies that DMD series subwoofers will produce tight and balanced bass notes in any car audio system.
