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 shorting ring on a flush-cut pole piece, with opposite polarity facing down, you redirect otherwise lost magnetic energy into the voice coil gap. This increases usable motor strength by 20-25%, allowing smaller, lighter motors to have the same drive energy as larger motors.
  • You cannot run a SuperCharged subwoofer at higher 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 the power handling is the same as the standard model.
  • Note: Supercharge subwoofers are made to order. Delivery time is 4-6 weeks in addition to the stated delivery time.

ESP Subwoofer Features:

  • Carbon Fiber Blend Cone (CFB) - The CFB composition uses an effective carbon fiber-based cocktail to offer you the highest strength-to-weight ratio in the industry.
  • Vario-Density Extended Range of Motion Surround (V-ROM) - Provides ultimate linear control at high excursion while enabling dynamically sounding bass reproduction. The control ribs are compressed to a lower density than the main surround body to allow a seamless control system. The harder you control it, the more control you get.
  • 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 spider diameter, cone diameter, suspension excursion, and thus acts as a secondary shorting ring, providing additional heat dissipation for better heat flow from the coil.
  • With the 1506, there is now an ESP subwoofer that fits into any installation, big or small.
  • SuperCharge option available!

Frequent questions about Power Tuned 1506 ESP


Wie schafft der Power Tuned 1506 ESP einen so kraftvollen Tiefbass trotz seiner kompakten Größe?

The Power Tuned 1506 ESP from DD Audio is a compact yet extremely powerful subwoofer, as it optimally utilizes the advantages of its 2" high-temperature voice coil. This special voice coil allows it to efficiently convert the magnetic field and reproduce the lowest frequencies with high precision. Especially if you enjoy listening to music at high volumes, you will see that this interplay of compact form and high-quality interior pays off. The Vario-Density Extended Range of Motion Surround ensures that the diaphragm remains clean and distortion-free even at high excursions. Additionally, the Carbon Fiber Blend Cone, an innovative material, provides an excellent ratio of stability to weight. This results in a subwoofer that not only delivers powerful bass but also fully unleashes its performance in very tight installation environments. This way, you benefit from solid pressure even in smaller vehicles without having to compromise on sound quality. Furthermore, DD Audio's expertise and the patented ferrite magnet system are evident in all details, allowing for a perfect combination of small size and strong sound.

Welche Rolle spielt das Carbon Fiber Blend Cone bei diesem DD Audio Subwoofer?

The Carbon Fiber Blend Cone (CFB) is a crucial feature of the Power Tuned 1506 ESP because it provides stability while keeping weight low. This special blend, based on carbon fiber, builds on DD Audio's expertise and gives the diaphragm an exceptionally high strength-to-weight ratio. So, if you want maximum pressure with punchy bass but don't want to install a subwoofer with excessive weight, the CFB is perfect. The lightweight material responds quickly to impulses and transmits low frequencies precisely and directly. Furthermore, it ensures an even distribution of vibrations, reducing distortion. The result is clean yet powerful bass that excites you even with demanding music genres. This design demonstrates how much value DD Audio places on maximum efficiency: you get a lightweight yet very robust sound body that ideally complements the subwoofer's load capacity and provides you with an intense audio experience without compromise.

Inwiefern verbessert das Tuned Spider System die Basswiedergabe des 1506 ESP?

The Tuned Spider System (TSS) is an important component of this high-end car subwoofer, as it is tailored to the specific requirements of different power ranges. DD Audio has tuned the system to keep the subwoofer stable under high loads without losing precision. Especially during fast passages with a lot of deep bass, you benefit from the TSS centering the diaphragm and minimizing unwanted patterns in the suspension. At high levels, it can quickly happen that the woofer loses precision or even bottoms out, but the TSS prevents such phenomena. Additionally, the Tuned Spider System works in harmony with the Vario-Density Extended Range of Motion Surround to allow for maximum excursion. This keeps the bass tight without blurring, even when you enjoy your favorite songs at the loudest level. Overall, the TSS not only enhances the sound quality but also the durability and longevity of your woofer.

Welche Vorteile bietet das Vario-Density Extended Range of Motion Surround im Alltag?

The Vario-Density Extended Range of Motion Surround (V-ROM) is a true highlight of the DD Audio Power Tuned 1506 ESP, as it provides more control and dynamics during large diaphragm excursions. If you enjoy listening to music with full bass, it can easily happen that the suspension of a sub is overwhelmed. The V-ROM concept counters this effect with a variably compressed structure: the control ribs have a lower density than the rest of the surround, ensuring a seamless transition at high excursions. The result: precise bass reproduction even at extreme levels and better control over diaphragm movement. Additionally, distortions are reduced because the sonic focus is always on clarity and stability in the movement of the voice coil. Especially if you value fine details and rich low frequencies, you will notice that you benefit enormously from this surround design. This way, you can turn up the volume without fearing that the sound will be compromised.

Wie trägt die Super-Frame-Technologie zum verbesserten Klang bei?

DD Audio's Super-Frame technology (SFrame) maximizes the available space for the spider and the cone, allowing for a larger diaphragm area to be utilized. If you desire a strong punch in the low-frequency range, this is a significant advantage. Additionally, the SFrame partially acts as an additional short-circuit ring while also providing enhanced options for more efficient heat dissipation. Especially during longer listening sessions with substantial power from your amplifier, the temperature in the voice coil system can rise quickly. However, the Super-Frame design allows excess heat to be better dissipated into the environment, which increases the overall stability and precision of the bass speaker. The way DD Audio cleverly utilizes this limited space is particularly remarkable at high volumes: the sound remains clean, the excursion is large, and distortions are effectively kept in check. This results in a harmonious interplay of power, precision, and durability, making the 1506 ESP especially attractive to discerning bass enthusiasts.

Worin bestehen die technischen Unterschiede zwischen dem Standardmodell und der SuperCharge-Option?

The SuperCharge option offered by DD Audio for the 1506 ESP utilizes a specially shaped neodymium short-circuit ring to direct otherwise unused magnetic energy into the voice coil gap. This increases the motor strength by 20–25 percent. As a result, you get a punchier and cleaner output when you prefer higher levels. Importantly, the load capacity remains the same because the heat dissipation and voice coil area do not change. This means you cannot apply more power than with the standard model, but you benefit from a more efficient use of the existing input. So, if you enjoy listening to more modern music genres with emphasized bass, the SuperCharge option can impress you with a clearer, tighter bass structure. However, it is not just a pure power increase, but an optimization of the drive that provides an even more precise sound image. Especially at high sound pressure levels, the advantage is that distortions are kept to a minimum. Nevertheless, the installation dimensions and the basic technical specifications remain almost identical to the normal 1506 ESP.

Wie wird beim Power Tuned 1506 ESP sichergestellt, dass die Hitze der Schwingspule kontrolliert bleibt?

The Power Tuned 1506 ESP employs several heat-reducing measures from DD Audio. On one hand, the subwoofer features a 2" high-temperature voice coil that is particularly thermally resilient. At the same time, the pole core bore is equipped with a grid, allowing for improved airflow around the voice coil. This enables a portion of the generated heat to be dissipated more quickly. The patented ferrite magnet system also plays an important role, as it efficiently controls the magnetic flux and minimizes unnecessary heat sources. Additionally, while the aluminum die-cast basket is extremely robust, it also has the ability to absorb heat and dissipate it to the environment. Together with the Super-Frame technology, this expands the overall cooling surface, providing you with noticeable advantages when listening at high levels: you can enjoy loud music for extended periods without encountering unpleasant distortion or overheating issues. This keeps the sound consistent and clear when you treat the 1506 ESP to your favorite songs at full volume.

Wie passt der 1506 ESP in Modelle von BMW, Audi, Mercedes oder VW, wenn der Platz begrenzt ist?

The 1506 ESP is quite compact with an outer diameter of only 19.2 cm and a mounting depth of 15.2 cm, which greatly facilitates integration into many common European vehicle models. Especially if you do not want to rely on gigantic subwoofer enclosures, you will find in this DD Audio subwoofer a space-saving alternative with excellent sound potential. In BMW, Audi, Mercedes, or VW models, it is often possible to accommodate an enclosure for the 1506 ESP even in smaller trunk or spare tire wells without any issues. You can rely on its clean bass performance without sacrificing unnecessary space in the vehicle interior. It is crucial to ensure that you have the appropriate volume and a stable installation so that you can truly take advantage of the compact size. This way, you still have enough room left while simultaneously bringing a full and precise bass into your vehicle.

Welche Frequenzen kann ich mit dem Power Tuned 1506 ESP abdecken und wie macht er sich im Alltag bemerkbar?

The playback range of the Power Tuned 1506 ESP extends from about 10 Hz to 500 Hz. This allows it to deliver deep bass in film or music recordings just as effectively as mid-bass in the kick bass range. For you, this means that you can make both extremely powerful kick drums and vibrating bass lines clearly audible without any sound gaps. In everyday life, you will notice how well this high-performance subwoofer can adapt: you can play quietly and still enjoy a full-bodied bass foundation, or you can turn it up and experience massive sound pressure. The resonance frequency of 47.8 Hz has a positive effect, as it provides a good foundation for many music genres. Whether you like nu-metal, hip-hop, or electronic beats – the 1506 ESP makes your favorite tracks shine. With a high power handling of 600 watts RMS, you can also deliver plenty of power without the sound becoming muddy or imprecise. This versatility is exactly what makes it an all-rounder that provides fun and realistic deep bass even on daily drives.

Wie sinnvoll ist es, diesen kompakteren DD Audio Subwoofer in Premium-Audio-Anlagen zu integrieren?

The Power Tuned 1506 ESP is excellent for premium audio setups because it relies on impressive technologies despite its compact size. Especially if you value standout pieces in your audio system, you will benefit from the high-quality Carbon Fiber Blend Cone, the Tuned Spider System, and the Vario-Density Extended Range of Motion Surround, which together ensure extremely clear and dynamic bass reproduction. Even in high-end vehicles, where often quite sophisticated speaker systems are already installed, this 6.5-inch subwoofer can provide the crucial portion of deep bass. You do not have to compromise on large enclosure dimensions, which can be particularly interesting in the premium segment if you want to keep the trunk discreet. At the same time, both the extended frequency range and the high power capability of 600 watts RMS are impressive. Thus, the 1506 ESP rounds off the overall experience by amplifying the system in a frequency range that conventional speakers cannot handle. This makes your listening experience even more exciting and vibrant.
