Product description

The Qi-SUB is the installation version of the Q-SUB and can be used to supplement Qi1, Qi7 and Qi10 cabinets in various combinations, either flown or ground stacked. It is acoustically compatible with the standard road version, differing only in cabinet construction and mounting hardware. The Qi-SUB cabinet is an actively driven bass-reflex design housing a long excursion 18" driver, its frequency response extending from 40 Hz to 130 Hz. The Qi-SUB 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. Four rubber pads placed into their recessed positions prevent movement of the cabinets when two or more Qi-SUBs are stacked. 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.
