JBL CSS-1S/T Compact Two-Way Surface Mount Dual Voltage Loudspeakers (pair)

The JBL CSS-1S/T is a compact two-way loudspeaker designed for use on 100V or 70V distributed speaker lines, or in 8 ohms direct mode.  The 135mm (5-1/4") low frequency loudspeaker and 19mm (3/4") polycarbonate dome tweeter reproduce full-range sound quality for foreground or background music and are voiced for maximum speech clarity and intelligibility. 

The rugged enclosure is fitted with an included, easy-to-install ball-type wall-mount bracket that can pivot to aim the speaker in a variety of directions, or the speaker can be aimded straight out from the wall.  The flat bottom surface of the cabinet allows the speaker to be set on a surface such as a shelf.
