The CIS300 (30-watt, 4-inch LF driver) compact two-way flush-mount ceiling loudspeaker employs a modified HF waveguide that integrates the HF driver with the LF driver, which is optimized for smooth frequency response and seamless transition through the crossover point. A welded tab is provided for seismic restraint, and two steel T-Bar support channels facilitate installation to a standard tile ceiling. A steel split C-ring is also provided. The integral 70-/100-volt line transformer is rated to a maximum of 30 watts, and power is adjustable via a recessed rotary switch on the front bezel, which also allows selection of 30, 15, 7.5, and 3.7 watt taps.
