HELIX CB C690.2-S3

HELIX COMPOSE. The perfect loudspeaker for every composition.

Born from the ever-increasing demands of modern vehicle technology and HELIX's signature pursuit of intelligent solutions, we made the advanced redesign of proven universal loudspeaker systems our mission. The result: the innovative HELIX COMPOSE platform, which, following the principle "designed in the car, for the car," combines classic universal loudspeakers with the advantages of vehicle-specific systems.

Innovative materials and cutting-edge technologies paired with smart, practical engineering – the best of both worlds in harmony: very high efficiency, fantastic sound quality, and enormous dynamics that fit into any vehicle. HELIX COMPOSE – Universal loudspeakers reimagined.

All the essentials for an exceptional sound experience

As the name suggests, our BASIC coaxial systems offer all the essentials for an exceptional sound experience in your car, providing the perfect foundation for entering the world of HELIX COMPOSE. All components are ideally matched and, together with our HELIX and MATCH amplifiers, form the perfect team, guaranteeing maximum performance and power output at all times.

Maximum efficiency

HELIX COMPOSE stands for smart engineering and is therefore based on highly efficient 3-ohm technology, which harmonizes perfectly with all HELIX and MATCH amplifiers, while simultaneously delivering a noticeably improved efficiency and maximum sound pressure level. Individual models will also be available as an optional 2-ohm version, which, in conjunction with suitable amplifiers, extracts the absolute maximum performance and power from the respective speaker component. Powerful bass – pinpoint accuracy. In the BASIC series, our COMPOSE mid-bass driver combines high efficiency with excellent sound quality. The lightweight yet robust polypropylene diaphragm ensures exceptional sound performance, while the torsionally rigid basket is equipped with additional ventilation openings for optimized cooling. A powerful magnet system is incorporated for ideal impulse response, and the soft polyurethane dust cap guarantees an optimized frequency response in the upper midrange. Last but not least, the compact design is ideal for integration in confined spaces. High frequencies with unique dynamics. Of course, precise highs are a must for a truly successful musical experience when entering the HELIX COMPOSE sound world. Our BASIC tweeter accordingly features a coated silk dome and a highly efficient neodymium magnet – the result: unique dynamics in high-frequency reproduction and crystal-clear sound.
