Helix Ci5 M80FM-S3 80 mm Midrange with FlexMount80 Technology

The HELIX Ci5 M80FM-S3 is a midrange driver designed for use in multi-way car audio systems, developed within the HELIX COMPOSE platform, which combines universal drivers with vehicle-specific integration solutions.

Positioned in the COMPOSE i5 series, the Ci5 M80FM-S3 is an intermediate solution between the i3 and i7 lines, with impedance optimized for pairing with HELIX and MATCH amplifiers, allowing efficient system management even in DSP configurations.

The driver was designed to deliver natural reproduction of the vocal range, good power handling, and adequate linear excursion for multi-way applications. The reduced external diameter, achieved without compromising the effective cone surface, facilitates installation in compact OEM locations. Compatibility with FlexMount technology further expands the possibilities for integration in different vehicles.

From a construction standpoint, the midrange uses a paper cone with silicone coating to improve damping and reduce resonances, a thin-profile surround to optimize excursion, and a neodymium magnetic system designed to contain distortion and size. The reinforced polymer basket contributes to mechanical stability and reduction of unwanted vibrations.

Ci5 M80FM-S3 Features

  • Advanced 3.15" / 80 mm midrange driver with exceptional audio performance and versatile physical integration options.
  • High efficiency and 3 ohm technology to maximize amplifier output power.
  • Silicone-coated paper cone for excellent impulse response and unmatched frequency response.
  • High-tech polymer composite basket reinforced with glass beads for exceptional rigidity and minimal resonance.
  • Special rubber surround and optimized magnetic system for large linear cone excursion.
  • Dedicated surround production enables smaller installation diameter and maximized effective cone area compared to typical 80 mm drivers.
  • Aluminum dust cap for optimized frequency response in the mid-high range.
  • Automotive-grade FlexConnect terminal for quick, secure, and failsafe connection.
  • Powerful neodymium push-pull magnetic system for maximum efficiency and extremely low distortion.
  • Two universal FlexMount80 mounting rings for vehicle-specific adaptation (e.g. Mercedes, Porsche, Tesla, etc.) or universal use included in the package
  • Optionally available: CFM80-100 adapter ring that allows the use of vehicle-specific FlexMount100 adapters optionally available for acoustically optimized and professional integration in the vehicle's original mounting position
  • Universal mounting ring with grille included in the package
  • Designed for vehicle-specific WireKits available as optional, which allow non-destructive integration
