DD Audio announced the “b” revision to its 9900 Series subwoofers, which are designed to produce and maintain precise lows for extended periods of play.
The subwoofers handle 1500-2500 watts RMS and a peak power of 10,000 watts.
DD Audio revised the 9900’s monstrous 75-pound motor structure to accommodate an American made, 8 layer, flat wound 4-inch aluminum voice coil. The result is a lower Fs driver with improved thermal handling. This heavy duty upgrade has made the 9900 Series stronger and longer lasting than ever before. Available in 12-, 15-,18-, and 21-inch frame sizes, the 9900 Series Power Tuned subs can be custom built with several different options.
