IQ Series - Audiophile Grade With Maximum Versatility
The Helix IQ range sets new benchmarks in the realm of high-performance subwoofers. Designed for discerning music enthusiasts who appreciate both powerful output and superior sound quality, these subwoofers combine cutting-edge technology, robust construction and outstanding flexibility. Featuring a proprietary tuneable mass system (TMS) which allows for precise customization of the bass response, these subwoofers are able to perform to their full potential in any application; whether it be compact sealed enclosures or high-output bass reflex systems.

Design Ideologies
The IQ range of subwoofers from Helix are engineered for high power and deep bass performance. With the recommended power range of 300 to 750 Watts continuous they offer a wide range of applications. They’re particularly optimized for high-power amplifier configurations, ensuring consistently precise bass reproduction even at extreme levels.

Wonderful Diaphragms
They feature a three layer fiberglass-mylar honeycomb cone which provides maximum rigidity and optimal internal damping; effectively minimizing distortion while ensuring tight, controlled and dynamic low-frequency performance. Exceptional transient response ensures that even complex bass passages are reproduced clearly and with absolute precision.

Cooling Off
A highly efficient cooling system featuring a large-diameter vented pole piece and an airflow-optimized basket design enables continuous air circulation, preventing overheating and thermal compression. This ensures consistent performance even under prolonged high-output operation, allowing the subwoofer to maintain full power and control at all times.

Proprietary Tuneable Mass System (TMS)
Fine tuning for your sound, the tunable mass system (TMS) introduces an innovative approach to bass adjustment; offering a unique way to customize the acoustic characteristics of the subwoofer. By adding or removing specific weights within the dust cap the moving mass of the driver can be modified, directly influencing the subwoofer’s response and efficiency.

Depending on the chosen configuration the subwoofer’s sonic profile changes significantly. Without additional weight the subwoofer maintains a higher resonant frequency; ensuring maximum efficiency and fast transient response which is ideal for high-output setups and tight, punchy bass reproduction. Adding mass lowers the resonant frequency allowing for deeper and more authoritative bass and making it particularly well-suited for sealed enclosures or low-tuned bass reflex systems.

This fine-tuning capability enables precise adaptation to enclosure volume and in-car acoustics. A higher moving mass extends low-frequency performance, whereas a lower moving mass improves efficiency; making the subwoofer suitable for operation with moderate amplifier power. This unparalleled flexibility makes the IQ range of subwoofers the ideal choice for those seeking ultimate sound precision and adaptability.

Flexible Connection for Seamless System Integration
The IQ range comes equipped in various voice coil configurations, meaning they offer maximum compatibility with various amplifier setups. Depending on the wiring configuration these subwoofers can be setup for various impedances, thus making them the perfect match for high-power monoblock amplifiers as well as multi-subwoofer configurations. This also makes for a seamless integration into both existing and newly designed sound systems.

Versatile Enclosure Options
Beyond its electrical adaptability the IQ subwoofers are designed for versatile enclosure compatibility. In sealed enclosures they deliver tight and controlled bass with outstanding transient response. While in bass reflex systems they provides exceptional low-frequency extension and immense output capability. This adaptability makes them the ideal choice for a wide range of system applications.

Sophisticated And Robust Construction
Delivering powerful low-frequency performance requires an exceptionally rigid and durable construction. The Helix IQ subwoofers features a meticulously engineered diecast aluminum basket, ensuring maximum stability while eliminating unwanted resonance. This guarantees consistent and precise bass reproduction, even during extreme cone excursion.

Additionally the subwoofer is equipped with a protective grille that is directly integrated into the basket. This secure mounting not only provides optimal protection for the cone but also allows for seamless integration into your vehicle’s interior. This ensures a safe and stylish installation which can be particularly advantageous in tight installation spaces or vehicles with limited mounting options, contributing to long-term reliable performance. Thanks to its sturdy construction the IQ range remain highly durable even under heavy loads, delivering pure and consistent sound quality for years to come.
