Helix Compose Basic 100mm / 4″ - 2-way standalone kit

The Compose Series speakers are optimized for Helix/Match DSP processors.

The Helix Basic is the most affordable collection in the Compose series, with an excellent price/quality ratio!

Like the other Compose models, the Basic is designed to be stationary in the car, which means that it is optimized specifically for in-car use.

This technology allows you to fit Compose Basic speakers to an almost infinite number of car models by simply changing the fitting ring to suit your car.
