Our speakers are typically used in professional wireless (radio) applications, e.g., systems operated by public authorities, control centers and air traffic control installations. The range of solutions concentrates especially on robust, compact speakers (e.g., KL1 and KL3 types) for wireless and GSM applications, as well as new pressure chamber loudspeakers (e.g., DHL1) rated for up to 25W and targeting railway applications, among others.
