Helix Compose Ci3 W200FM-S2 – 2 Ohms 8″ Woofers With Grills

Description

HELIX Ci3 W200FM-S2

Overview
The HELIX COMPOSE i3 series delivers excellent performance and value, combining smart engineering with high-quality components for precise, dynamic sound. All models are optimized for use with HELIX and MATCH amplifiers to ensure maximum power output and seamless integration.

High Efficiency
The i3 series uses advanced 2 Ohm technology for enhanced amplifier performance, delivering clear, powerful sound with improved efficiency. The system is designed to work perfectly with HELIX and MATCH amplifiers for maximum sound pressure and minimal distortion.

Cenosphere Paper Cone
The “Cenosphere” coating process integrates hollow spheres within a polyamide layer on the cone surface. This increases stiffness while improving internal damping, resulting in a lightweight yet rigid cone that delivers accurate and detailed sound reproduction.

High-Tech Polymer Basket
Each speaker features a polymer composite basket reinforced with glass beads for exceptional rigidity and reduced self-resonance. The material also minimizes flux modulation and resists temperature effects, allowing for compact dimensions and easy installation even in tight spaces.

FlexMount200 – Universal and Vehicle-Specific Fit
The FlexMount200 system uses specially designed adaptor rings to allow installation in a wide range of vehicles. This design enables the woofer to fit perfectly into factory locations while maintaining acoustic optimization.

ProConnect – Reliable Connection System
The ProConnect terminal supports both conventional speaker cable connections and plug-in options via HELIX WireKits. It provides a secure, reverse polarity-protected connection built to automotive standards, ensuring durability and stability.

WireKits – Plug & Play Integration
HELIX WireKits enable quick and secure integration with the vehicle’s original wiring harness or crossover. Designed to automotive-grade specifications, they ensure reliable performance under demanding in-vehicle conditions.
