A suitable placement area would be the trunk or a specially designed bass box.
The patented ferrite magnet system of the Power Tuned 9921b is special because it offers higher efficiency in energy conversion, thus optimizing sound quality even at high volumes. Ferrite magnets are known for their stability and ability to ensure high performance even under intense use. This property makes the subwoofer ideal for users who expect consistently high-quality bass without loss of performance. The ferrite magnet system also allows for finer tuning of sound waves, resulting in precise and powerful bass reproduction across the entire frequency range. This is particularly advantageous for dynamic music pieces.
The 4 inch (101.6 mm) spool diameter of the Power Tuned 9921b has several advantages. A larger spool diameter allows for more windings and a larger wire diameter, which improves heat dissipation and increases the lifespan of the coil. This feature is particularly important when the subwoofer is operated at high power for extended periods. A larger diameter also contributes to overall performance, as more energy can be converted into acoustic power. This is crucial for achieving the high power levels for which this subwoofer is known and contributes to a powerful and clear sound image.

21 (53cm) subwoofer for rich bass: At a glance

The DD Audio Power Tuned 9921b is equipped with a 21 (53cm) subwoofer, which delivers powerful bass. A subwoofer of this size not only offers impressive sound volume, but also a depth of detail that smaller units often lack. A larger diameter also enables deeper bass reproduction, which is perfectly integrated into the frequency range from 10Hz to 500Hz. This makes the subwoofer particularly suitable for vehicles with sufficient space to accommodate such powerful units. Compared to 15 and 18 models, you can expect a more intense bass performance.

With a resonant frequency (Fs) of 26.24 Hz and a quality factor (Qts) of 0.47, the subwoofer is specially designed to reproduce low frequencies cleanly and efficiently. The equivalent volume (Vas) of 161.9 L further supports this capability, while the Xmax of +-22 mm allows for large cone excursions to remain distortion-free even at high levels. A too low Xmax value, on the other hand, would limit bass reproduction. With these parameters, you've made the right choice for maximum sound fidelity in the low bass range.

Magnetic protection and accessories: All-round protection for use

The DD Audio Power Tuned 9921b comes with comprehensive magnet protection and a cap with a grille in front of the pole piece hole. These protective measures effectively prevent damage to the delicate structure that could be caused by external influences. The additional magnet protection cap ensures that no dirt or metal particles can damage the magnet. Without this protection, the subwoofer would be more susceptible to environmental influences that could degrade the sound over time. The included accessories ensure that the subwoofer can perform optimally right from the start.
