SC-12 is a passive coaxial 12" speaker (LF-Neodymium) and 1,75" driver(1" voice coil) with a two-way passive crossover, and is ideal to be mounted with an Omega Clamp (not included) on a truss using the appropriate U-bracket (not included). It has 3 speakON connectors, two on one side, one on the other. You can also use it as a monitor wedge on the stage floor thanks to its design. The speaker is 400Waes, so we recommend you use a 800 WRMS amplifier.
