The SuperCharge Option

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

Features ESP Subwoofer

  • Carbon Fiber Blend Cone (CFB) - The CFB composition uses an effective carbon fiber-based cocktail to provide you with the highest strength-to-weight ratio in the industry.
  • Vario-Density Extended Range of Motion Surround (V-ROM) - Offers ultimate linear control at high deflection while enabling dynamically sounding bass reproduction. The control ribs are compressed to a lower density than the main surround body to allow for a stepless control system. The harder you control it, the more control you gain.
  • Tuned Spider System (TSS) - Each suspension is tuned to specific performance characteristics, e.g. High Definition, Power Handling, X-Stiff Control.
  • Super-Frame (SFrame) - Maximizes the spider diameter, the cone diameter, the suspension deflection, and thus acts as a secondary short-circuit ring and provides additional heat dissipation for better heat flow from the coil.
  • SuperCharge option possible!
The Power Tuned 9912b ESP from DD Audio is a 12-inch subwoofer with a power handling capacity of up to 10,000 watts. It uses a Carbon Fiber Blend Cone for an optimal strength-to-weight ratio, while the Vario-Density Extended Range of Motion Surround provides precise linear control. The Tuned Spider System ensures specific performance characteristics, and the Super-Frame maximizes the spider diameter for improved excursion. Igneousium magnets and a 4-inch voice coil diameter ensure high performance. The frequency range extends from 10Hz to 500Hz, with a resonance frequency of 31.63 Hz.
The SuperCharge option of the Power Tuned 9912b ESP enables a tighter and cleaner bass by utilizing a specially shaped neodymium short-circuit ring to use magnetic energy more efficiently. By redirecting the lost magnetic energy, the motor strength is increased by 20-25%, leading to more efficient energy use. Although the SPL rate does not increase, one benefits from clearer sound reproduction at high volumes without affecting heat dissipation or voice coil area. The SuperCharge option does not change the basic load capacity and is made to order, requiring an additional delivery time of 4-6 weeks.
The Power Tuned 9912b ESP offers two impedance options: a dual 1 Ohm and a dual 2 Ohm configuration. This flexibility allows you to optimally adapt the subwoofer to your existing audio landscape, whether through parallel connection for a lower impedance or series connection for a higher impedance. This ensures broad compatibility with various amplifiers, and by choosing the impedance, the power output and operation of the system can be finely tuned. Therefore, it is possible to adjust the power requirements of the system to the conditions of the vehicle or the preferred configuration.
The 12-inch Woofer Power Tuned 9912b ESP uses a Carbon Fiber Blend Cone (CFB) for superior performance characteristics. This special CFB composition significantly improves the strength-to-weight ratio, which directly results in precise control and reduced distortion at high levels. The Carbon Fiber Blend provides a balance between stability and lightness, which in turn contributes to high responsiveness and a smoother transition across different frequency ranges. This way, you get bass that is not only powerful but also clear and detailed, across the entire sound spectrum.
The Vario-Density Extended Range of Motion Surround (V-ROM) of the Power Tuned 9912b ESP is a highly advanced environment that ensures ultimate linear control. It enables dynamic bass reproduction thanks to the compressed control ribs, which, when controlled harder, provide enhanced control. This construction reduces mechanical distortions and allows for extended freedom of movement, resulting in smoother bass notes. The V-ROM optimizes the density ratios within the surround structure, ensuring that bass reproduction remains particularly powerful and linear during long excursions of the diaphragm. This contributes to the overall excellence and efficiency of the 9912b ESP.
The Power Tuned 9912b ESP subwoofer offers an RMS power handling of 2500 watts and a peak power handling of an impressive 10000 watts. The RMS power handling represents the maximum continuous power consumption that the subwoofer can maintain without damage over extended periods. In contrast, the peak power is the maximum power value that the subwoofer can handle for short moments. This means that during dynamically intense audio signals that require more energy in the short term, the subwoofer can manage these peaks. However, when planning the audio system, the RMS power handling should primarily be considered to ensure stable and long-term performance.
The playback range of the Power Tuned 9912b ESP is between 10Hz and 500Hz. This allows you to reproduce extremely low-frequency sounds with this subwoofer, which are particularly important for bass-heavy music. The ability to reproduce up to 500Hz also allows for seamless integration with other speakers in the system, which often cover the mid to high frequency range. The resonance frequency of the 9912b ESP is at 31.63 Hz, which means it can work particularly strongly in this frequency range to create a powerful bass foundation, especially in music tracks that emphasize a heavy bass line.
The Tuned Spider System (TSS) in the Power Tuned 9912b ESP optimizes performance by tuning into the strongest characteristics of the suspension for high definition, power handling, and X-Stiff control. Each component is calibrated to maximize its respective potential, resulting in exceptionally precise sound experiences. The tuned spider ensures extended freedom of movement while providing structural support to prevent collapses or distortions at maximum excursions. TSS contributes to improved dynamics and sensitivity, allowing the subwoofer to deliver admirably stable sound results even at high power levels.
The Power Tuned 9912b ESP is equipped with a 4 inch (101.6mm) voice coil, which, in conjunction with the large magnet weight of 1500 Oz, enables effective power transfer. The generous coil diameter allows for the processing of larger amounts of energy while maintaining linearity and precision throughout the entire stroke. The significant magnet weight ensures that the coil is held precisely in place, guaranteeing a reliable and powerful audio experience. This combination of coil diameter and magnet provides powerful bass with excellent responsiveness even at higher volumes.
The Super-Frame (SFrame) of the Power Tuned 9912b ESP maximizes the spider diameter and excursion while functioning as a secondary short-circuit ring. This design improves heat dissipation, thereby increasing the efficiency of the subwoofer. Since the cone diameter and the excursion of the suspension are maximized, the SFrame allows for improved air circulation around the voice coil and reduces heat build-up, enabling a longer operational lifespan while maintaining consistent performance. Additionally, it enhances the structural integrity of the subwoofer by effectively buffering external forces, resulting in consistent sound reproduction even under high-performance conditions.
