HELIX Ci7 W130-S3

HELIX COMPOSE. The perfect loudspeaker for every composition.

Born from the ever-increasing demands of modern vehicle technology and HELIX's typical 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 "developed in the car, for the car," combines classic universal loudspeakers 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: Very high efficiency, fantastic sound quality, and enormous dynamics that fit into every vehicle. HELIX COMPOSE – Universal loudspeakers reimagined.

i7 – High-End Car HiFi “Made in Germany”

The HELIX COMPOSE i7 series represents uncompromising high-end for an extravagant sound experience in the car.

With a clear influence from its high-end sister brand BRAX, the i7 loudspeaker series is entirely "made in Germany" and optimized for pure musical enjoyment. The impedances of all loudspeakers are perfectly matched to our HELIX and MATCH amplifiers, guaranteeing maximum performance and power output at all times. Furthermore, we have implemented new mechanical technologies in HELIX COMPOSE, which offer unparalleled practical benefits.

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 and simultaneously enables a noticeably improved efficiency and maximum sound pressure level.

UHD (Ultra High Damping) Paper Cone

As already familiar from our sister brand BRAX, the i7 series, true to our In line with our uncompromising high-end philosophy, we use only the highest quality materials, such as our proprietary, hand-molded UHD (Ultra High Damping) paper cone. This is manufactured using a particularly elaborate process and guarantees optimal frequency response and the best possible impulse response for unparalleled musical enjoyment. High-Tech Polymer Composite Basket: All HELIX COMPOSE i7 and i3 speaker baskets are made of a high-tech polymer composite material, which is further reinforced with glass beads. The result: maximum stability with minimal resonance, while also eliminating flux modulation of the magnet system and providing maximum resistance to thermal influences. Finally, this allows for significantly more compact basket dimensions and thus simplified installations in confined spaces.

ProConnect – The new industry standard

Our innovative ProConnect terminal reflects the new industry standard: It is a professional, automotive connector that enables the safe use of conventional speaker cables, but is also ideally suited for connection via flat connectors with our WireKits, thus offering maximum flexibility when designing sound system upgrades. Furthermore, the connection is locked, offers reverse polarity protection, and is electrically and mechanically highly resilient.
