DD9500g

The 9500 'g' Series was designed with a singular goal in mind, to achieve the highest possible volume levels with a ferrite motor and to do so with the least distortion. The 9500 models are the most copied and cloned subs in today's car audio market, some even copy the name.

The new 'g' series design takes the 95's to even higher performance levels with a magnet system utilizing over 23 pounds of material and increasing the number of machined cooling vents.. These goals combine high efficiency, extended range of motion and high power handling in one package. 95's are engineered without compromise, and without a marketing department trying to capitalize on trendy fads. The long gap design keeps the highly efficient voice coils under power beyond 3 inches of throw. Voice coil control at extreme levels is crucial to clean output. The machined motor structure features the FREE FLOW COOLING SYSTEM which pumps cooling air through and around the voice coil with each and every stroke.

The SFB cone is a model of a high strength-to-weight ratio modern cone. These synthetic blend cones are strong enough not to flex at extreme power levels and light enough to react to quickly changing signals. The cone fibers like Kevlar, Polyester and Sisal allow less material to have higher strength than conventional cones and this low mass contributes to a fast transient response, which in turn lowers distortion. The suspension must also be engineered to many conflicting criteria to lower distortion at high excursion. The surround is the now often imitated EROM profile. This DD innovation allows long excursion while lowering mass and maximizing cone area. The spiders follow the same principal, reduce the surface area while increasing the corrugation heights. This results in long controlled motions while minimizing coil rocking and unwanted moving mass.

The 9500 'g' Series might be the ultimate woofer, hand assembled to the tightest tolerances in order to reproduce music as exact as possible, at whatever volume level you desire.


We recommend to allow at least several weeks of playing time to break in DD Woofers, full break in may take many months. DO NOT play subwoofers at max amplifier power in the first couple of days, give the suspensions a chance to loosen up. As the suspension breaks in, the subs will play lower and louder.
After you give the woofers a chance to break in (you'll know when this happens because the woofers will be playing lower and louder) you can start to look at port changes to alter the sound to your personal taste and your vehicles acoustic loading conditions.
