Helix Compose CB C460.2-S3 – 4″x6″ Coaxial Speakers

HELIX CB C460.2-S3

Overview

A high-efficiency 2-way coaxial speaker system that delivers clear, dynamic, and balanced sound performance. The HELIX COMPOSE series combines practical design with modern technology to provide a strong upgrade solution for car audio systems, ensuring excellent sound quality and smooth installation across various vehicles.

Essential sound performance

The BASIC component systems are designed to offer everything needed for an enjoyable listening experience. Each part works in harmony to deliver accurate and powerful sound reproduction. When paired with HELIX or MATCH amplifiers, the result is consistent performance and efficient power handling.

High efficiency

Engineered with 3 Ohm technology, this system delivers greater amplifier performance and improved sound output. The optimized impedance allows for a noticeable boost in sound pressure and clarity without distortion.

Powerful and controlled bass

The midbass driver is built for both strength and responsiveness. Its lightweight polypropylene diaphragm ensures accurate and punchy bass, while the steel basket includes additional ventilation for improved heat management. The strong magnet system enhances impulse response, and the soft polyurethane dustcap helps maintain a smooth frequency transition.

Refined high frequencies

The 0.75” (20 mm) tweeter features a coated silk dome paired with a neodymium magnet, producing detailed, natural, and distortion-free treble. It ensures high efficiency and a balanced sound across all frequency ranges.
