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

The Compose series is optimized for Helix / Match DSP processors.

Helix Basic is the most affordable and best value for money model in the Compose series!

As with the other Compose models, the Basic is designed to be car-mounted, so it is optimized specifically for car use.

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

Compose Basic speakers are compatible with FlexMount20 adapters.
