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

SPECIAL NOTE:
LIKE ALL DUAL VOICE COIL SUBWOOFERS A DUAL 2 OHM SUBWOOFER IS ACTUALLY A 1 OHM OR A 4 OHM SUBWOOFER, IT WILL NEVER BE JUST 2 OHMS   
AND A DUAL 4 OHM SUBWOOFER IS ACTUALLY A 2 OHM OR A 8 OHM SUBWOOFER-IT WILL NEVER BE JUST 4 OHMS

BE CAREFUL WHEN DESIGNING YOUR AUDIO SYSTEM AND YOUR SELECTION OF AMPLIFIER/SUBWOOFER COMBINATION(S)
LOWER IMPEDANCE IS NOT A GOOD THING. DAMPENING FACTOR OF THE AMPLIFIER SUFFERS (HOW IT CONTROLS THE SUBWOOFER) AND THE HEAT OF ANY AMPLIFIER DOUBLES WITH EVERY HALVING OF IMPEDANCE. NOT A GOOD THING
REMEMBER THAT HEAT IS YOUR ENEMY
