Precision Power DCX 124

The DCX (Dynamically Controlled eXcursion) subwoofer continues the PrecisionPowerfi tradition of high performance and innovation that dates back to the flat piston, high-power Pro-series. DCX subs feature a unique new motor design called Dual Gap Geometry or DGG (patent pending) that centers a short, lightweight voice coil between two magnetic gaps. The resulting ultralight moving mass is driven through a far more linear stroke by the flatter, extended magnetic field. Careful balancing of excursion limits and power handling results in what is almost certainly one of the most accurate, high output subwoofers available. Dual spiders on a ventilated spider ring keep the moving mass centered throughout its stroke, and improve airflow for better cooling. The DGG motor assembly uses a cluster of smaller magnets arranged around the vented pole piece as well as a more conventional magnet assembly for the lower half of the motor. All of this results in a subwoofer that maintains extreme linearity and limits distortion while keeping its cool at power input up to 1,000 watts. The new proprietary die-cast basket and other custom-tooled integral parts mean that DCX subs look as sweet as they sound.
