Helix Compose Basic 130mm / 5,25″ - 2 way standalone set

Helix Basic is the most affordable and best value for money collection in the Compose range!

As with other Compose models, the Basic has been developed in the car, which means that it has been optimised specifically for car use.

One of the key elements of the Compose range is a patented mounting system called FlexMount, which is based on specially developed speaker adapters.
This technology allows you to mount Compose Basic speakers on an almost infinite number of car models by simply changing the fitting ring that fits your car.

The Compose Basic series is compatible with FlexMount20 adapters.
