The i.Flex15.1 is a 2-way full range cabinet which is driven by an integrated passive crossover. It is equipped with a direct radiating 15” low-mid speaker and a 1” compression driver on a rotatable CD horn.

The new developed horn with a directivity of 75° x 50° with its square opening is rotatable by 90°. Several bass systems are available for applications where an expanded low-end frequency range is required.

The i.Flex15.1 is suitable for public address applications up to a distance of 20 meters. Because of its linear setup, no system controller is required.
