CSB-20T and CSB-40T are design and compact surface mount speakers to broadcast speech and music. They are EN 54-24 certified, so they can be used for voice alarm installations. The speakers are equipped respectively with a 3” and 4” full range transducers. With 20W and 40W power, both models offer optimal performances for any kind of application. They integrate high impedance outputs for 100V and 70V installations. The built-in transformer gives the choice of three or four power levels depending on the model. Made of ABS resin the cabinet is scratch and shock resistant.
