Helix CB C130.2-S3 - 3Ohm
Helix Compose Basic 130mm / 5.25 - 2-way coaxial speaker.
Helix Basic is the most affordable model in the Compose series and offers a great price/quality ratio!
Like other Compose models, Basic was developed in-car, which means it has been optimized specifically for in-car use.
One of the key elements of the Compose series is a patented mounting system called FlexMount, which is based on specially developed speaker adapters.<br>
This technology allows you to install Compose Basic speakers in an almost infinite number of car models by simply changing the adapter ring that fits your car.
