CEI400 (PZA)
TWO-WAY CEILING SPEAKER
The CIS400 is a complete two-way bass-reflex flush-mount speaker system designed for fixed installations in typical ceiling spaces. By employing a unique HF waveguide design based on leading brand studio monitors, the CIS400 offers superior pattern and dispersion control over conventional coaxial designs. The waveguide integrates the HF driver with a 6.5″ LF driver optimized for smooth frequency response and a seamless transition through the crossover point. The result is extraordinary acoustic performance not typically associated with a commercial ceiling speaker in this price range.
The CIS400 is supplied fully assembled, with a sealed zinc-coated steel rear container and cam-style mounting brackets. The metal housing includes a flush-mounted Euroblock input connector with removable male plug, concealed behind a hinged metal cover plate. A welded flange is provided for seismic restraint. Two steel T-bar support channels are provided for easy installation on a standard tile ceiling. A steel split C-ring is also supplied, which serves to disperse the clamping pressure of the mounting cams.
The CIS400 is supplied with an integral 70/100V line transformer with a maximum power of 30 watts. The power can be adjusted using a rotary switch recessed into the front bezel and allows you to select taps of 30, 15, 7.5 and 3.7 watts. A second recessed rotary switch is provided to activate a 16 ohm tap for use with low impedance amplifiers or a 150 Hz high-pass filter.
The speaker assembly ships with a removable plastic cover placed over the transducers inside the bezel. This protective cover protects the conductors from damage during installation and also serves as a paint cover, allowing for convenient spray painting to match interior decor. A powder-coated perforated steel grille is supplied and is easily installed once the tap selector and desired full-range/high-pass switches have been configured.
The speaker is designed for use in ceiling plenum spaces and complies with UL 1480 and UL 2043 standards governing signaling devices and plenum applications.
