8.0 inch subwoofer in 8 Ohms
More Control, More Power, More Everything
This little subwoofer will still let you run with the big bass dogs.
Truly big bass, from a truly small conveniently-sized subwoofer with all the great features of the larger dX Subs. It's optimized for small sealed enclosures, and delivers deep, tight, musical bass. It may be small, but it has room for all the great dX Sub Series features:
- Polymer and graphite composite cones-the stiffest cones in the autosound industry, 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-allowing you to choose the impedance that suits your personal system design, including exotic isobaric and push-pull types.
