RCF ST15 SMA

The RCF ST15 SMA Active PA Speaker is a high-quality and practical solution for audio applications, presentations and music with or without a subwoofer.  The ST15 works very well as a side-fill or delay line and has superb sound quality, even at higher sound pressure levels. 

The ST15 is a 1200W active speaker and has a maximum sound pressure of 131dB. It boasts a 15” high power woofer with 2.5” voice coil which delivers accurate and punch bass notes and has precise frequency control.  The 1” high fidelity driver is custom made from resistant polyimide for increased stability and strength. 

The ST15 can also function very well as a monitor loudspeaker and on the back of the speaker’s housing is a flat / boost switch where the EQ can be switched between optimized monitor mode and normal.

There is also an ergonomic carry handle for easy and comfortable transportation. An integrated DSP manages the EQ, soft limiter, compressor, dynamic bass boost and the crossover.  Three LEDs indicate power, the active limiter and the status monitor operation.
