Helix IQ W12-DVC2 (Q431203) high-performance 12 inch / 300 mm subwoofer with innovative Tuneable Mass System and dual 2 x 2 Ohm voice coil

The HELIX IQ W12-DVC2 sets new standards in the high-performance subwoofer sector. Designed for the most demanding music enthusiasts who appreciate both high power and superior sound quality, this subwoofer combines cutting-edge technology, robust construction and exceptional flexibility. Thanks to its proprietary Tuneable Mass System (TMS), it allows precise customization of bass response, enabling it to fully express its potential in any application, whether in compact sealed enclosures or in high-power bass reflex systems.

Designed for high-power performance and deep bass

With a recommended power range of 300 to 750 Watts RMS, the HELIX IQ W12-DVC2 offers a wide range of applications and is particularly optimized for high-power amplifier configurations, ensuring accurate bass reproduction even at extreme levels. Its 3-layer fiberglass and Mylar honeycomb cone ensures maximum rigidity and optimal internal damping, effectively reducing distortion while ensuring precise, controlled and dynamic low-frequency performance. The exceptional transient response ensures that even the most complex bass passages are reproduced clearly and with absolute precision.

A highly efficient cooling system, characterized by a large-diameter ventilated magnetic pole and an air-flow optimized basket design, allows continuous air circulation, preventing overheating and thermal compression. This ensures consistent performance even during prolonged high-power operation, allowing the subwoofer to maintain full power and control at all times.

The Tuneable Mass System (TMS) introduces an innovative approach to bass tuning, offering a unique way to customize the acoustic characteristics of the subwoofer. By adding or removing specific weights inside the dustcap, you can modify the driver's moving mass, directly influencing the subwoofer's response and efficiency.

Depending on the configuration chosen, the subwoofer's sound profile changes significantly. Without additional weights, the subwoofer maintains a higher resonance frequency, ensuring maximum efficiency and fast transient response - ideal for high-power configurations and precise, punchy bass reproduction. Adding mass lowers the resonance frequency, allowing deeper and more authoritative bass, making it particularly suitable for sealed cabinets or bass reflex systems with low resonance frequency.
