DD Audio Power Tuned 9918b ESP

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. A 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 is equipped with the Evolution Subwoofer Package (ESP). ESP-equipped drivers feature larger diameter suspensions and deeper frames than standard subwoofers, as well as exclusive surround and cone designs. ESP subwoofers are truly built to maximize performance in their respective size class.

The 9900 Series comes standard with an oversized black composite drywall dust cap, red logo, and treated cellulose cone, but can be optioned with alternative composite dust caps, composite cones, powder coated frames, boost, and a variety of logo options to give your subwoofer a custom look and/or added performance for a specific application.
ESP Subwoofer Features:
  • Carbon Fiber Blend Cone (CFB) - The CFB composition uses a potent carbon fiber-based cocktail to give you the highest strength-to-weight ratio in the industry.
  • Vario-Density Extended Range of Motion Surround (V-ROM) - Provides the ultimate in linear control at high excursion while enabling dynamic-sounding bass response. The control ribs are compressed to a lower density than the main surround body to provide a stepless control system. The harder you control it, the more control you get.
  • Tuned Spider System (TSS) - Each suspension is tuned for specific performance characteristics, e.g. High Definition, Power Handling, X-Stiff Control.
  • Super-Frame (SFrame) - Maximizes spider diameter, cone diameter, suspension deflection, thus working as a secondary shorting ring and providing additional heat dissipation for better heat flow from the coil.
  • SuperCharge option possible!
  • 46cm (18") subwoofer
  • Power handling (RMS): 2500 Watt
  • Peak power handling (Peak): 10000 Watt
  • Impedance options: Double 1 Ohm or Double 2 Ohm
  • Patented ferrite magnet system
  • Lossless linear suspension
  • Ribbed foam surround
  • Magnetic protection cap incl. grid in front of pole core hole
  • Aluminum die cast basket


  • Playback range 10Hz - 500Hz
  • DC resistance (Re) 0.9Ohm
  • Resonant frequency (Fs) 26.24Hz
  • Mechanical quality (Qms) 2.265
  • Electrical quality (Qes) 0.51
  • Total quality (Qts) 0.47
  • Equivalent volume (Vas) 161.9 L
  • Xmax +-22mm
  • Magnet weight 1500 Oz
  • Coil diameter 4" (101,6mm)

SuperCharge Option:

  • With the Supercharge option, you'll hear even tighter and cleaner bass across the entire power bandwidth.
  • What exactly happens with SuperCharging? By adding a specially shaped neodymium shorting ring on a flush cut pole piece, with the opposite polarity down, you redirect otherwise lost magnetic energy into the voice coil gap. This increases the usable motor power by 20-25%, allowing smaller, lighter motors to have the same drive energy as larger motors.
  • You can't run a SuperCharged sub at more power and the SPL value doesn't increase, but you will hear cleaner output at higher levels. SuperCharged subwoofers use the power you give them more efficiently, but you still have the same heat dissipation and voice coil area. That means the power handling is the same as the standard model.
  • Info: The Supercharge subwoofers are made to order. The delivery time is 4-6 weeks in addition to the stated delivery time.
