15″ High-Power Loudspeaker

The Flex15 is a bi-functional high-power loudspeaker and is equipped with a 15″ cone loudspeaker and a 15″ high frequency driver. The 75° x 50° radiating horn is rotatable to achieve 50° x 75° directivity.

A complex passive crossover matches the components perfectly and allows for full-range application without additional electronics. The Flex15 is a universal tool which can be used as a FoH speaker, as a wedge, and as a mid-high unit in combination with our Flex-Series Subs. For easy and efficient cable connection as a wedge or near-fill, 4 Speakon NL4 are available. There are two connectors on the rear and two on the bottom.
