Subwoofer Helix IQ W10 DVC2

Subwoofer Helix IQ W10 DVC2

Before first use, you must install the included screw with a wedge locking washer into the dust cap, as described in the "Tuneable Mass System Installation Manual". This step is necessary even if you do not plan to use additional tuning weights.

HELIX IQ W10-DVC2 – a top-tier subwoofer with maximum flexibility

The HELIX IQ W10-DVC2 sets a new standard among high-performance subwoofers for demanding listeners. It was engineered to combine extraordinary power with premium sound quality and to allow precise acoustic tuning thanks to the patented Tuneable Mass System (TMS). This enables it to excel both in compact sealed enclosures and in high-output bass-reflex designs.

Power and sound without compromise

The subwoofer is optimized for 300–750 W RMS and pairs ideally with powerful amplifiers. It features a three-layer honeycomb cone made of glass fiber and Mylar, providing extreme stiffness and effective damping. This results in minimal distortion, fast transient response and precise bass reproduction—even at extreme volumes. An advanced cooling system with a large vented pole piece and an airflow-optimized basket design ensures constant air flow, prevents overheating and allows the subwoofer to deliver stable performance under prolonged high load.

Tuneable Mass System – tailor the response

The patented TMS system allows fine adjustments to the moving mass of the driver by adding or removing weights in the dust cap. This makes it possible to precisely tailor the bass character to the specific application:

• without additional mass – higher efficiency and faster response, ideal for high-power systems,
• with additional mass – deeper, denser bass, perfect for sealed or low-tuned bass-reflex enclosures.

This unique flexibility lets you adapt the sound and enclosure volume to the listener’s needs and the specific vehicle.

Flexible wiring and compatibility

Thanks to the dual 2 × 2 Ohm voice coils, the subwoofer can be wired in multiple configurations—from 1 Ohm up to 4 Ohms. This makes it suitable for monoblock amplifiers as well as multi-subwoofer systems and varied system requirements. The HELIX IQ W10-DVC2 is well suited to sealed enclosures for tight, precise bass, as well as to bass-reflex cabinets where it shines at producing extremely deep frequencies with massive output.

Robust and sophisticated construction

The pressure-cast aluminum basket provides maximum rigidity and eliminates unwanted resonances. The integrated protective grille shields the cone while also simplifying installation in confined spaces. Thanks to its durable construction and smart design, the subwoofer remains reliable over the long term and can deliver clean, dynamic bass performance for many years.
