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.

Simon Lennartz (Kreuzrath Jugendgruppe):
We had listened to the Flex 12 and Magnus 12 in direct comparison. We were surprised how well the significantly cheaper Flex 12 compared to the Magnus section. In the end, however, we chose the Magnus 12 because it reproduces instruments and speech even more authentically and because the guys from AD-Systems have provided us with presets for our existing amplifiers. Without having to buy new amplifiers, we were able to invest the money saved in the better speakers. Thank you!
