Product Overview

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 can be driven either by the d&b D6 or D12 dual channel power amplifiers configured for the C7-SUB. More detailed information on specific loudspeaker setups with d&b amplifiers is available either in the relevant loudspeaker or amplifier manuals.
