dX Subwoofers—More Bass, Less Space

The dX Series of subwoofers use the latest technologies and highest quality mate-

rials to provide you with the best bass response and greatest reliability possible. The
dX subwoofers have been optimized to give the kind of skull-collapsing performance
one would expect from huge enclosures in boxes that take up a fraction of the trunk
space. Some of their design elements are:

• Polymer and graphite composite cones—the stiffest cones in the

autosound industry are able to withstand the enormous pressures generated
inside small enclosures without breakup and distortion.

• High mass cones—allows awesome low frequency tuning in

small enclosures.

• Thick ABS dustcap—prevents distortion due to the build up of air pressure

behind the cap.

• High durometer rubber surrounds—provides a much tighter and more

durable air seal behind the cone than foam, paper or cloth surrounds, for deep,

tight, quick bass. Also, rubber surrounds do not dry rot like the foam surrounds
used by other manufacturers.

• Extra long, precision wrapped, vented coils—for superior cooling

and high power handling.

• Four layer, 2" voice coil—handles the heat generated when your amp is

really cranking.

• Vented pole piece—lets air circulate over the voice coil to keep it cool

and in control even when the bass is really thumping.

• 8 Ohm and 4 Ohm versions available—allows you to choose the

impedance that suits your personal system design, including exotic isobaric
and push-pull types.
