9900 Revision – The Beast Just Got Meaner


Oklahoma City, OK, December 27th, 2018 — It is with great excitement that DD Audio is announcing the “b” revision to their 9900 Series subwoofers. Designed to produce and maintain precise lows for extended periods of play, with an RMS power band of 1500-2500 watts and a peak power of 10,000 watts, the 9900 Series boasts the highest power handling in the Power-Tuned line-up.

A long-time favorite among champion bassheads, the 9900 Series was already one of DD Audio’s toughest subs, but they found a way to improve this beast’s bass arsenal.

DD Audio revised the 9900’s monstrous 75lb motor structure to accommodate an American made, 8 layer, flatwound 4” aluminum voice coil. The result was 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” frame sizes, the 9900 Series Power Tuned subs can be custom built with several different options.
