The Ci7-SUB is the installation version of the C7-SUB. It is acoustically compatible with the standard road version differing only in cabinet construction and mounting hardware. The Ci7-SUB is a bass-reflex subwoofer that employs a large, specially shaped reflex port enabling the Ci7-SUB to achieve high sound pressure levels with minimal power compression and breathing effects. The Ci7-SUB cabinet is constructed from marine plywood with an impact resistant paint finish. The front of the loudspeaker cabinet is protected by a rigid metal grill, covered with acoustically transparent foam. Four M16 threaded inserts are provided for attaching installation hardware. The cabinet rear panel is fitted with a single NL4 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 d&b 30D and D20 amplifiers are recommended to drive the Ci7-SUB. The d&b 10D, D80, D6 and D12 amplifiers can also be used with the appropriate loudspeaker configuration selected.
