HELIX CB K130.2-S3

A high-performance 2-way component speaker system designed for excellent sound quality and easy installation in almost any vehicle. Built for those who value balanced audio, clear highs, and dynamic bass in a compact, durable setup.


Essential Sound Performance

The BASIC component systems in the COMPOSE lineup provide everything needed for a clear, detailed listening experience. Each part is designed to work seamlessly with HELIX and MATCH amplifiers for maximum performance. The tweeter design also ensures secure and professional installation.


High Efficiency

This speaker system uses 3 Ohm technology to deliver strong output and efficiency. It pairs effectively with most amplifiers, offering noticeable improvement in power and sound pressure. Optional 2 Ohm models are available for setups that need additional performance.


Powerful Bass

The bass-midrange driver combines efficient power use with clean sound reproduction. Its polypropylene cone ensures rigidity without excess weight, while the steel basket includes extra ventilation for cooling. The strong magnet system ensures accurate response, and the compact design fits tight spaces.


Crisp High Frequencies

The tweeter features a coated silk dome and a neodymium magnet for detailed high-frequency sound. This combination results in bright, natural highs with strong dynamics.


Optimized Crossover

The crossover includes a 4-step tweeter level control (12 dB slope) and built-in protection. Compact and fine-tuned, it helps balance the sound across all frequencies for a smooth overall experience.


Flexible Mounting – FlexMount20 System

The FlexMount system allows easy installation in a wide variety of vehicles. Using optional FlexMount20 adapter rings, the tweeter can be mounted in factory positions while maintaining ideal acoustic alignment.
