HELIX CB C165.2-S3
HELIX COMPOSE. The perfect speaker for any composition.
Born out of the increasingly demanding challenges of modern automobile technology and the HELIX-typical pursuit of intelligent solutions, we made the progressive redesign of proven universal speaker systems our mission. The result: our innovative HELIX COMPOSE platform that, according to the motto "developed inside the vehicle, for the vehicle", combines classic universal speakers with the advantages of vehicle-specific systems. Innovative materials and the latest technologies paired with smart, practical engineering – the best of both worlds in harmony: high efficiency, fantastic sound quality, and enormous dynamics that fit in any vehicle. HELIX COMPOSE – universal speakers evolved.
The essentials for an exceptional sound experience
Our BASIC component systems are the perfect introduction to HELIX COMPOSE, providing all the essentials for an exceptional sound experience. All components harmonize perfectly with HELIX and MATCH amplifiers, guaranteeing maximum performance and power output.
High efficiency
HELIX COMPOSE implements highly efficient 3 Ohm technology, harmonizing perfectly with all HELIX and MATCH amplifiers while providing maximum sound pressure. Optional 2 Ohm variants are available for maximum performance with appropriate amplifiers.
Powerful bass – always on point
The BASIC midbass driver combines high efficiency with excellent sound quality. Lightweight but stable polypropylene diaphragms provide exceptional performance, while the sturdy basket has ventilation holes for optimized cooling. A powerful magnet system ensures ideal impulse response, and the soft polyurethane dustcap optimizes upper midrange frequency response. Compact design fits easily in tight spaces.
High frequency reproduction with unique dynamics
The BASIC tweeter uses a coated silk dome and highly efficient neodymium magnet for unique dynamics in high-frequency reproduction and crystal-clear sound.
