The models of the CST series are frameless in-ceiling speakers with a particularly discreet appearance for installation in hotels, restaurants, bars, foyers, training and conference rooms or shopping centers. The 2-way coaxial systems have a frequency response of up to 20 kHz, balanced sound and excellent speech intelligibility. The tweeter is protected against overload by a PTC and can be tilted 30 degrees to adapt to local conditions, as well as freely rotated by 360°. Secure mounting clamps allow for fast and easy attachment. The front grille is exchangeable.
