Helix CB K165.2-S3
Helix Compose Basic 165mm / 6.5″ - 2-way separate set
The ohm rating of the Compose series speakers is optimized for the Helix / Match DSP processors.
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.
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.
Compose Basic stand-alone kits are compatible with FlexMount20 adapters.
