Power Tuned 9512k ESP

Powerful bass performance thanks to 2000 watts RMS and 8000 watts peak power

Discover the impressive bass performance of the Power Tuned 9512k ESP from DD Audio. This 12-inch subwoofer delivers a whopping 2000 watts RMS and an impressive 8000 watts peak power handling. This power will satisfy even the most demanding music playback and ensure powerful, precise low frequencies. The enormous power handling enables dynamic audio reproduction that covers the entire frequency range from 10 Hz to 500 Hz. Compared to conventional models on the market, this model stands out with its exceptional performance, guaranteeing clear and distortion-free sound even at high volumes. A lower RMS value would significantly compromise maximum volume and sound quality.

Efficient control thanks to Vario-Density Extended Range of Motion Surround (V-ROM)

The DD Audio subwoofer's Vario-Density Extended Range of Motion Surround (V-ROM) technology provides exceptional control at high excursions. This is achieved through the graduated density of the control ribs, which allows for continuous adjustment. This technology ensures linear diaphragm movement, even under extreme loading, thus maximizing suspension and excursion. Less sophisticated suspension systems could result in distortion and loss of sound quality at high outputs. The V-ROM increases linearity and provides dynamic bass reproduction that sets itself apart from other systems.

Durable materials thanks to Carbon Fiber Blend Cone (CFB)

The Carbon Fiber Blend Cone (CFB) of the 9512k ESP subwoofer sets a new standard in material selection. This carbon fiber-reinforced structure offers an unrivaled strength-to-weight ratio. This innovative combination of materials is crucial for precise bass reproduction and reliability. Multiple layers of fiber ensure optimal stability with minimal weight, enabling rapid movement response. Without a CFB structure, the cone's mobility would be limited, potentially resulting in a less controlled soundstage. The DD Audio subwoofer guarantees responsive, powerful, and clear bass.

Optimal heat dissipation through super frame with secondary short-circuit ring

The Super-Frame design of the 9512k ESP not only maximizes the cone and spider diameters, but also provides enhanced heat dissipation. The integrated secondary shorting ring plays a critical role in this by improving heat flow from the coil. This feature ensures efficiency and longevity during intensive use. A suboptimal cooling system could lead to voice coil overheating and, in the long run, damage the subwoofer. The DD Audio subwoofer overcomes this with its advanced construction, enabling it to remain stable under intense conditions.

Tuned Spider System (TSS) technology for tuned performance characteristics

The performance-engineered Tuned Spider System (TSS) provides the 9512k ESP with essential features such as high definition, power handling, and X-Stiff Control. Each suspension component has been specifically engineered to promote specific performance characteristics. This focus on individual needs increases adaptability to different musical styles and performance requirements. With a differentiated spider system, consistent performance is achieved, unlike standard systems that can cause more frequent failures or performance degradation. The TSS creates responsive acoustics that are flexible and powerful.

Impedance options for flexible configuration: Double 1 Ohm and Double 2 Ohm

The Power Tuned 9512k ESP offers flexible impedance configurations with dual 1 ohm or dual 2 ohm impedances. These options allow for precise tuning to suit different amplifier setups and operating requirements. A lower impedance allows more power to be drawn from the amplifier, which can result in a louder and more bass-capable system. However, this places greater demands on the amplifier itself. This range of impedance options allows the user to optimize the subwoofer for their specific application, ensuring optimal sound matching and efficiency.

Efficient sound conversion through patented ferrite magnet system

The DD Audio subwoofer is equipped with a patented ferrite magnet system, which ensures the efficient use of magnetic energy in sound conversion. This technology increases energy conversion, thus delivering powerful, clear sound. The ferrite magnet is known for its high temperature stability, which is advantageous for intensive bass applications. Unlike inferior magnet materials, the ferrite reduces the risk of magnetization loss, keeping the sound more powerful and consistent. This magnet system is a key feature that efficiently supports the subwoofer's power drive.

Enhanced performance with the optional SuperCharge option

With the SuperCharge option, the 9512k ESP achieves even more efficient use of its available power. A specially shaped neodymium shorting ring redirects lost magnetic energy back into the voice coil gap. Although power output is not increased and SPL remains the same, clarity at high levels is improved. This technology allows smaller motors to retain the functionality of larger models without compromising power handling. The result is tighter bass that can offer effective versatility at high frequencies. Orders require a lead time of 4-6 weeks.
