Frequently Asked Questions about Power Tuned 9912b ESP

What technical features does the Power Tuned 9912b ESP have?

The Power Tuned 9912b ESP from DD Audio is a 12-inch Subwoofer with a power handling capacity of up to 10000 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.

How does the SuperCharge option affect the sound of the 9912b ESP?

The SuperCharge option of the Power Tuned 9912b ESP allows for tighter and cleaner bass by utilizing a specially shaped neodymium short-circuit ring to use magnetic energy more efficiently. By redirecting lost magnetic energy, the motor strength is increased by 20-25%, leading to more efficient energy use. Although the SPL rate does not increase, you benefit from clearer sound reproduction at high volumes without compromising heat dissipation or voice coil area. The SuperCharge option does not change the basic power handling capacity and is made to order, requiring an additional delivery time of 4-6 weeks.

What impedance options does the Power Tuned 9912b ESP offer?

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 match the Subwoofer to your existing audio landscape, whether through parallel wiring for lower impedance or series connection for 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 system's power requirements to the vehicle's conditions or the preferred configuration.

How does the Carbon Fiber Blend Cone (CFB) of the 9912b ESP ensure better performance?

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, contributing to high responsiveness and a smoother transition across different frequency ranges. This gives you bass that is not only powerful but also clear and detailed, across the entire sound spectrum.

What is the Vario-Density Extended Range of Motion Surround (V-ROM) in the 9912b ESP and what does it do?

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 allows for dynamic bass reproduction thanks to the compressed control ribs, which, when controlled harder, provide increased 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.

How does the load capacity differ between RMS and peak power in the Power Tuned 9912b ESP?

The Power Tuned 9912b ESP Subwoofer offers an RMS load capacity of 2500 watts and a peak load capacity of an impressive 10000 watts. The RMS load capacity represents the maximum continuous power intake that the subwoofer can maintain without damage over extended periods. In contrast, the peak load 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 load capacity should primarily be considered to ensure stable and long-term performance.

What frequencies can the Power Tuned 9912b ESP reproduce?

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, meaning 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.

What advantages does the Tuned Spider System (TSS) of the 9912b ESP Subwoofer offer?

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 displacements. TSS contributes to improved dynamics and sensitivity, allowing the Subwoofer to deliver impressively stable sound results even at high excursion levels.

What is the diameter of the coil and magnet used in the Power Tuned 9912b ESP?

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 processing larger amounts of energy while maintaining linearity and precision throughout the entire excursion. 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.

What makes the Super-Frame (SFrame) of the Power Tuned 9912b ESP unique?

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 suspension excursion are maximized, the SFrame allows for improved air circulation around the voice coil and reduces heat build-up, enabling longer usage times while maintaining performance. Additionally, it strengthens the structural integrity of the Subwoofer by effectively buffering external forces, leading to consistent sound reproduction even under high-performance conditions.

Es lohnt sich!

Ich habe sie an den Sounddigital 800.4 Evo6 angeschlossen. Und ich bin mehr als zufrieden. Mitteltöner laut und auch präzise. Hochtöner brennen nicht in den Ohren, die sind laut und geben das, was sie sollen. Gut angelegtes Geld.

Laut ... einfach nur laut

Also ich sag es mal so... wenn man ein Lautes Kompo System sucht, mit noch sehr guten Klangeigenschaften.
Naja der sollte das T3 von Rockford nehmen.
Ich hatte viele Systeme verbaut und bin dann wieder zurück zum T3 und habe nun 3 verbaut... schön laut und sehr feiner Klang.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.
