The Ci45 is a full range, 2-way bass-reflex cabinet designed specifically for permanent installation. In the standard, upright operating position the CD horn is positioned below the LF driver so the HF dispersion is less likely to be influenced by reflections from walls, ceilings or other equipment mounted nearby. This arrangement improves the headroom before feedback when systems are flown above the stage. The cabinet is constructed from marine plywood and has an impact resistant paint finish. The front is protected by a rigid metal grill fitted with an acoustically transparent foam. M10 threaded inserts are provided on the top and bottom, and on the sides of the cabinet, for mounting rigging accessories. A recess at the top of the rear panel, which also serves as a handle, is fitted with an NL4 input connector. The loudspeaker cabinet is also available in Special Colour (SC) and Weather Resistant (WR) options.
The d&b audiotechnik loudspeaker range is designed exclusively for operation with d&b amplifiers. These provide power as well as comprehensive control and protection functions tailored to achieve the performance, reliability and longevity associated with the d&b System approach. The Ci45 can be driven by either the d&b D6 or D12 amplifiers, with the appropriate loudspeaker configuration selected.
