Helix Compose Ci3 W130-S3 – 5.25″ Woofers – 3 Ohms

Description

HELIX Ci3 W130-S3

HELIX COMPOSE. Premium sound for any setup.
Engineered to meet the demands of modern vehicles, this series represents a refined redesign of universal speaker systems. The HELIX COMPOSE platform combines advanced materials, precise engineering, and practical design to deliver high efficiency, clear sound, and dynamic performance suitable for any vehicle.

Price-Performance Highlight
The i3 series delivers excellent sound quality at an affordable price. High-quality components and smart engineering ensure reliable performance. All speaker impedances are optimized for use with HELIX and MATCH amplifiers for consistent maximum output.

High Efficiency
3 Ohm technology enhances efficiency and sound pressure while harmonizing perfectly with compatible amplifiers.

Cenosphere Paper Cone
Hollow spheres embedded in a polyamide coating improve cone stiffness and internal damping. This produces a stable yet lightweight cone for precise and detailed sound reproduction.

High-Tech Polymer Basket
The basket is made from polymer composite reinforced with glass beads, ensuring rigidity with minimal resonance. It reduces distortion, resists thermal stress, and allows for compact installation in tight spaces.

ProConnect Terminal
The ProConnect terminal provides a reliable connection for standard speaker cables or flat plugs via WireKits. Connections are interlocked, reverse-polarity protected, and designed to withstand mechanical and electrical stress.

WireKits – Plug & Play
WireKits allow simple connection to the vehicle’s original wiring harness or crossover. Built to automotive standards, they ensure convenient, durable installation even in demanding conditions.
