DD's final opponent with an incredible 21 inches, 53cm diameter.
The 9900s are the entry level subwoofer for the discerning bassaholic with a deep interest in physics. Entertaining minds will delight in the endless system design possibilities that come with these precision woofers.

The 9900 was originally called The Beast and first appeared on the market in the early 2000s. It took a while, but now it's back and beastier than ever. The latest version was designed in response to the recent explosion of ultra-low frequency music. These subwoofers were designed to provide long term power handling, accuracy and high excursion characteristics. They have been optimized for a power band of 1500 - 2500 watts and can handle bursts of up to 10,000 watts. One look at the 9900 motor shows why we call it the Beast. It has a 3 inch magnet cross section, a 10″ OD and weighs 35kg (just the motor). The traditionally narrow DD magnet gap drives a 4″ flat-wound aluminum voice coil to a peak excursion of more than 7.5cm, leaving enough turns in the gap to maintain power and control.

The 9900 Series comes standard with an oversized black composite drywall dust cap, red logo, and treated pulp cone, but can be optioned with alternative composite dust caps, composite cones, powder coated frames, charging, and a variety of logo options to give your subwoofer a custom look and/or added performance for a specific application.
