Ceiling speaker with high efficiency and good speech reproduction. Especially for installation in metal ceilings (e.g. ships). A push-terminal block allows a quick and easy connection to the 100-V-network including the eventually necessary level adjustment. After screwing the speaker to the ceiling a quick-mounting bayonet connection provides an easy installation of the grille.
Typical applications:
- Installation in metal ceilings
