The BS-634 and BS-634T are wall-mount speakers matched with a supplied plug-in speaker receptacle for easy installation. The 6W rated input BS-634/634T are 5 (12cm) cone-type speakers. An M4 screw terminal input connector allows easy connections. The speakers are driven on a high-impedance (100V or 70V) line with rated inputs. A selectable attenuation function is provided on the BS-634T. The speaker enclosure’s design proportions are based on the Golden Ratio (1: 1.618). A low profile blends in well with room dÈcor. Both vertical and horizontal installations are possible. Enclosure and grille net colour is off-white.
