12″ Compact Loudspeaker

The Flex12 is a compact bi-functional high-power loudspeaker and comes equipped with a 12″ cone loudspeaker and a 1″ high frequency driver. The 75° x 50° radiating horn is rotatable to achieve 50° x 75° directivity.

A complex passive crossover matches the components working perfectly together and allows a full-range application without additional electronics. The enclosure of the Flex12 is angle symmetrical and allows mirrored use. The Flex12 is a universal tool which can be used as a small FoH speaker, as a compact wedge with a very low profile, 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 connectors are available, 2 on the rear and 1 NL4 each on the top and on the bottom.
