Rugged design for marine and motorsport conditions: Element Ready™ and IPX6 certification

Specifically designed for extreme conditions, these subwoofers are waterproof and weatherproof thanks to their IPX6 certification. The Element Ready™ design ensures they can withstand harmful UV rays and splashing water, making them ideal companions for marine adventures. Constructed from 100% UV-stable ASA plastic, the enclosure won't weaken under harsh environmental conditions, ensuring your subwoofer will last even in the harsh marine environment.

High-temperature Kapton™ voice coil for exceptional sound experiences

The subwoofers are equipped with a high-temperature-resistant Kapton™ voice coil with a 1.5-inch (38.6 mm) diameter. This advanced voice coil provides increased durability and performance at high outputs. While a larger voice coil would allow for more power, this diameter strikes a balance between efficiency and thermal resilience.

Innovative connection solutions for easy installation and secure connection

The industry's first in-frame connectors significantly simplify cabling and, with additional Deutsch™/Amphenol™ connectors, ensure a secure and error-free connection. This sophisticated design not only simplifies installation but also minimizes the risk of connection errors. The zinc-nickel-plated brass terminals also offer excellent corrosion resistance and long-lasting conductivity, especially under marine conditions.

Optimized acoustic performance through VAST surround and polypropylene membrane

Thanks to the VAST vertical mounting technology, the effective radiating cone area is increased by up to 25%. This co-molded Santoprene surround, combined with a mineral-filled polypropylene cone body, improves overall rigidity, resulting in a more precise soundstage. This design feature is crucial for even frequency distribution and supports the linear and distortion-free operation of the subwoofers.

Efficient impedance settings with VERSA switch for flexible configurations

The VERSA impedance switch allows you to quickly switch between different wiring options for the DVC models, without the need for additional cabling. This allows you to configure the system in parallel or series, depending on the specific application. This allows you to match the impedance to your existing audio system to maximize the subwoofer's performance and avoid overloading.

Perfect edge illumination thanks to nano-coated ventilation motor design

The ventilated motor design with a water-repellent, nano-coated mesh screen incorporates advanced technology that not only protects the motor structure from environmental influences but also optimizes heat dissipation. These features ensure longevity and efficient power transfer. Greater efficiency could further increase overall power transfer, but the current design already demonstrates outstanding results in audiophile practice.

Impressive SPL of 87.5 dB: Optimal volume and clarity

A sound pressure level (SPL) of 87.5 dB @ 1W/1m offers an excellent balance between loudness capability and sonic precision. With performance above average for its product category, this subwoofer delivers rich, voluminous bass reproduction without compromising sound quality. Higher SPL values ​​could lead to clipping, while lower values ​​may impair bass reproduction.

Thiele-Small parameters for precise bass reproduction: Vas, Qms, Qts and Qes analyzed

The VAS value of 15.7 liters, a mechanical quality factor (Qms) of 12.3, an electrical quality factor (Qes) of 0.98, and a total quality factor (Qts) of 0.90 demonstrate the exceptional bass capabilities of this subwoofer. While the VAS represents the speaker cabinet size, the Qts reflects the bass output. These parameters indicate an optimal balance between compliance and restoring force, resulting in tight and precise bass reproduction. These values ​​could be adjusted to meet different market requirements or tonal preferences. Customer support is just as important as technical excellence.
