HELIX IQ W12-DVC2 | 30cm subwoofer with TMS | 2x2 ohms

Audiophile sound quality with maximum adaptability

The HELIX IQ W12-DVC2 sets new standards in the field of high-performance subwoofers. Designed for discerning music lovers who appreciate both powerful levels and precise sound quality, this subwoofer offers an outstanding combination of innovative technology, robust construction, and unique flexibility. Its specially developed Tunable Mass System (TMS) allows for individual adjustment of the bass response, enabling it to reach its full potential in any application – whether in compact sealed enclosures or powerful bass-reflex enclosures.

Maximum performance for the deepest bass

With a recommended power range of 300 to 750 watts RMS, the HELIX IQ W12-DVC2 has a wide range of applications and is particularly optimized for high-performance amplifier configurations. Its robust construction ensures consistently precise reproduction, even at high levels over extended periods. The 3-layer fiberglass-Mylar honeycomb cone combines maximum rigidity with optimal internal damping, minimizing distortion and achieving dynamic, controlled bass reproduction. Outstanding impulse response ensures that even complex bass lines are reproduced clearly and precisely without loss of definition. A highly efficient cooling system with a large pole piece vent and flow-optimized basket design ensures continuous airflow. This prevents overheating and thermal compression effects, allowing the subwoofer to deliver consistently high performance even under continuous load. Tunable Mass System (TMS) – Mechanical fine-tuning for your sound. With the innovative Tunable Mass System (TMS), the HELIX IQ W12-DVC2 offers a completely new way to customize your sound. By selectively adding or removing weights within the dust cap, the subwoofer's moving mass can be varied. This adjustment alters the Thiele-Small parameters and thus directly influences the resonant frequency, the overall Q factor, and the efficiency of the subwoofer. Depending on the chosen configuration, the sound signature changes significantly. Without added weight, the resonant frequency remains in the upper range, resulting in particularly fast impulse response and high efficiency. This tuning is perfectly suited for volume-optimized setups and precise bass reproduction with maximum headroom. With increasing mass, the resonant frequency decreases, allowing the subwoofer to reproduce lower frequencies with greater impact. This is particularly advantageous for sealed enclosures or low-tuned bass-reflex designs, as it enables a particularly voluminous and powerful bass response. The ability to adjust the moving mass allows for precise tuning of the subwoofer to the specific enclosure volume and the acoustic properties of the vehicle. While a higher moving mass allows for a lower cutoff frequency, a lower mass maintains higher efficiency, enabling the subwoofer to be operated efficiently even with moderate amplifier power. This unique flexibility makes the HELIX IQ W12-DVC2 a perfect choice for anyone who demands the highest sound precision and maximum adaptability. Versatile Integration Options: The HELIX IQ W12-DVC2 is equipped with a 2 x 2 ohm dual voice coil to ensure maximum adaptability to different amplifier systems. Depending on the wiring, the subwoofer can be operated with a total impedance of 1 ohm or 4 ohms, in addition to the typical 2 x 2 ohm configuration, making it perfectly suited to powerful monoblock amplifiers or complex multi-subwoofer setups. This offers exceptional flexibility when it comes to optimally integrating the subwoofer into an existing or newly planned sound system. In addition to the electrical connections, the mechanical design has also been optimized for versatile installation options. The subwoofer is suitable for both sealed and bass-reflex enclosures and can be ideally used in various vehicle types. In sealed enclosures, it impresses with controlled, precise bass reproduction and excellent impulse response, while in bass-reflex designs, it unleashes its full potential and reproduces low frequencies with impressive impact. Robust design for long-lasting performance. Powerful bass reproduction requires a robust construction. The HELIX IQ W12-DVC2 is equipped with a high-quality die-cast aluminum basket that prevents unwanted resonances and ensures vibration-free operation. This guarantees consistent, precise reproduction even at maximum excursions. Additionally, the subwoofer features a protective grille integrated directly into the basket. This sturdy mounting not only provides optimal protection for the diaphragm but also allows for seamless integration of the subwoofer into the vehicle's design. This ensures a secure and stylish installation, which can be a crucial advantage for long-term reliable performance, especially in confined spaces or vehicles with limited space. Thanks to its robust construction, the HELIX IQ W12-DVC2 remains durable even under heavy use and delivers pristine sound quality for years to come.
