HELIX Ci7 M100FM-S3 – High-End Midrange Speaker Made in Germany

The HELIX Ci7 M100FM-S3 is part of the HELIX COMPOSE i7 series, built for uncompromising high-end audio performance in vehicles. Designed and manufactured entirely in Germany, the i7 series combines audiophile-grade materials, advanced engineering, and compatibility with HELIX and MATCH amplifiers for maximum performance and precision.

Engineered with highly efficient 3 Ohm technology, it maximizes amplifier output while ensuring superior sound pressure and clarity. Its handcrafted UHD (Ultra High Damping) paper cone, inspired by the sister brand BRAX, guarantees outstanding impulse response and unmatched frequency accuracy.

The high-tech polymer basket, reinforced with glass beads, ensures maximum rigidity, minimal resonance, and excellent thermal resistance, while remaining compact for simplified installations. With the FlexMount100 system, the speaker can be universally installed or easily adapted to OEM-specific mounting positions. Additionally, the FlexConnect terminal ensures a plug-and-play, automotive-standard connection with reverse polarity protection.
