Helix Compose Ci7 W200FM-S3 – 8″ Woofers With Grills – 3 Ohms

Description

HELIX Ci7 W200FM-S3

A precision-engineered speaker system designed for premium in-car audio performance. The HELIX COMPOSE series brings together innovation, refined materials, and expert craftsmanship to deliver clear, powerful, and dynamic sound. It perfectly combines high efficiency, detailed frequency response, and modern installation flexibility for any vehicle setup.

i7 – High-End Sound Engineering Made in Germany

The HELIX COMPOSE i7 series represents high-end automotive audio at its best. Entirely developed and manufactured in Germany, it ensures exceptional accuracy and musicality. Every component is precisely matched for use with HELIX and MATCH amplifiers, ensuring peak power and clarity. The series incorporates new mechanical innovations for superior reliability and performance.

High Efficiency

Engineered with a 3-Ohm design, the i7 series ensures maximum amplifier efficiency and enhanced sound output. The system maintains high sound pressure levels and low distortion, delivering clean, dynamic performance even at higher volumes.

Ultra High Damping (UHD) Paper Cone

Each i7 speaker uses a specially crafted UHD paper cone made through a detailed and complex manufacturing process. This cone achieves outstanding stiffness and damping balance, resulting in accurate impulse response and a natural, distortion-free sound.

High-Tech Polymer Basket

Constructed from a polymer composite reinforced with glass beads, the basket offers high rigidity and minimal resonance. This structure resists heat and prevents magnetic field interference, providing stability and durability while allowing compact dimensions for easier installation in tight spaces.

FlexMount200 – Universal and Vehicle-Specific Integration

The FlexMount system allows adaptable installation using custom adaptor rings. It enables the speaker to fit seamlessly into factory mounting positions in various vehicles, achieving acoustically optimized results without modification.

ProConnect – Professional Connection Standard

The ProConnect terminal ensures a secure and professional-grade connection. It supports both traditional speaker wiring and plug-in options for rapid installation using compatible WireKits. The system features reverse polarity protection and is designed for durability under automotive conditions.

WireKits – Simple Plug & Play Integration

Optional WireKits provide a quick and non-destructive connection between HELIX COMPOSE components and the vehicle’s original wiring or external crossovers. Built to automotive standards, these kits guarantee safety, reliability, and ease of installation.
