Entertaining minds will revel in the endless system design possibilities deliverable with these precision low-frequency devices.\u003c\/p\u003e\n\u003cp\u003eOriginally coined The Beast, the 9900s first appeared on the market in the early 2000s. It took a brief hiatus, but now it’s back and more beastly than ever. The latest iteration was developed in response to the recent explosion in ultra-low-frequency music. These subwoofers were designed to provide long-term power handling, with accuracy, and high excursion capabilities. It’s been optimized for a 1500 – 2500 watt power band with the ability able to handle bursts of up to 10,000 watts. One look at the 9900 motor and you see why we call it the beast. It boasts 3 inches of magnet cross-section, over a 10″ OD, and weighs in at 70 pounds (motor only). The traditionally tight DD magnet gap drives a 4″ flat wound aluminum voice coil to a peak excursion in excess of 3 inches while keeping enough turns in the gap to maintain power and control.\u003c\/p\u003e\n\u003cp\u003eThe 9900 Series features our Evolution Subwoofer Package (ESP).
