Product Overview

The Qi7 is the installation version of the Q7 loudspeaker. It is acoustically compatible with the standard road version differing only in cabinet construction and mounting hardware. The Qi7 is a passive 2-way loudspeaker with a rotatable constant directivity horn and a passive crossover network. The two 10" neodymium LF drivers are positioned in a dipolar arrangement providing exceptional vertical dispersion control with the 40° nominal dispersion angle being maintained down to 400 Hz. The Qi7 horn can be rotated by 90°.

The Qi7 can be driven either by the d&b D6 or D12 dual channel power amplifiers configured for the Q7. More detailed information on specific loudspeaker setups with d&b amplifiers is available either in the relevant loudspeaker or amplifier manuals.

Applications

Features

The Qi7 cabinet is constructed from marine plywood and has an impact resistant paint finish. The front of the loudspeaker cabinet is covered with a replaceable acoustically transparent foam that is then protected by a rigid metal grill. Four M10 threaded inserts on each side panel of the cabinet enclosure are provided for attaching installation hardware. The cabinet rear panel is fitted with two NL4 connectors wired in parallel. The loudspeaker cabinet is also available in Special Colour (SC) and Weather Resistant (WR) options.
