Helix CB K130.2-S3 - 3Ohm

Helix Compose Basic 130mm / 5.25″ - 2-way separate set
Helix Basic is the most affordable collection of the Compose series with a great price/quality ratio!
Like other Compose models, Basic has also been developed in-place in the car, thanks to which they have been optimized specifically for car use.
One of the key elements of the Compose series is the patented mounting system called FlexMount, which is based on specially developed speaker adapters.

With this technology, you can install Compose Basic speakers in an almost infinite number of car models by changing the adapter ring that fits your car.
Compose Basic separate sets are compatible with FlexMount20 adapters.
