Helix Compose Ci3 K130.2-S3 – 5.25″ 3 Ohm Component Set

HELIX Ci3 K130.2-S3

A 2-way component speaker system designed for precise sound reproduction, efficient performance, and reliable installation. It uses advanced materials and engineering for detailed audio, smooth treble, and solid bass response — suitable for compact installation spaces without compromising quality.

Performance highlight

The Ci3 system provides the essential balance of accuracy and efficiency expected from a high-performance 2-way setup. Built from premium materials with a focus on consistent power delivery, each component works seamlessly with HELIX and MATCH amplifiers for optimal sound and stable operation.

High efficiency

Equipped with 3-Ohm technology, the system maximizes amplifier performance, offering higher sound pressure levels and improved energy efficiency.

Cenosphere paper cone

The midbass cone features a lightweight paper base with a special Cenosphere coating that enhances stiffness and damping. This results in a responsive, distortion-free output with clean midrange detail.

High-tech polymer basket

The speaker basket is built from a high-tech polymer composite reinforced with glass fibers. It ensures strong rigidity, minimizes resonance, and withstands heat without affecting sound quality, making it suitable for compact installations.

Clear highs with stable response

The 0.75” (20 mm) tweeter uses a titanium dome that maintains stability, low weight, and excellent damping for crisp and distortion-free treble across various frequencies.

Optimized crossover

The Ci3 FX-UNI.2 crossover provides precise filtering and a 6-level tweeter adjustment with 12 dB slope for balanced integration. It also includes tweeter protection and supports COMPOSE Connect and WireKit systems for safe and straightforward setup.

COMPOSE Connect

A plug-in connection system that allows secure and simplified installation while preventing polarity errors, ensuring professional integration without soldering.

FlexMount20 – adaptable installation

The optional FlexMount20 adaptor rings allow the tweeters to fit into factory mounting points for vehicle-specific installation with optimized acoustic positioning.

WireKits – easy connection

WireKits provide a plug-and-play connection to the factory harness, following automotive-grade manufacturing standards for durability and ease of use.
