The Qi1 is the installation version of the Q1 line array loudspeaker. It is acoustically compatible with the standard road version differing only in cabinet construction and mounting hardware.
The Qi1 cabinet is a passive 2-way design that houses 2 x 10" LF drivers and a 1.3" HF compression driver with a toroidal wave shaping device to achieve a 75° × 15° (h × v) dispersion characteristic. The frequency response extends from 60 Hz to above 17 kHz. The two 10" neodymium LF drivers are positioned in a dipolar arrangement providing an exceptional dispersion control even at lower frequencies with the 75° nominal dispersion angle being maintained down to 400 Hz.
The Qi-SUB subwoofer extends the system frequency response to below 40 Hz, for further extension of bandwidth and headroom ground stacked B2 subwoofers can be used (driven in INFRA mode).
The Qi1 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 weather resistant (WR) version comes supplied with a fixed cable.

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 75° × 40° passive 2-way loudspeaker housing 2 × 10" LF drivers and a 1.3" HF compression driver 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 precisely controlled 75° horizontal dispersion performance provides the ideal pattern for many medium throw requirements. The Qi7 horn can be rotated by 90°. The horizontal Qi7 set up with rotated horn is used to mount the loudspeaker horizontally where space is limited, or the maximum horizontal pattern control is needed. The rotated set up is also used when Qi7s are added horizontally to the bottom of Qi1 arrays.
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 weather resistant (WR) version comes supplied with a fixed cable.

The Qi10 is the installation version of the Q10 loudspeaker. It is acoustically compatible with the standard road version differing only in cabinet construction and mounting hardware.
The Qi10 is a 110° × 40° passive 2-way loudspeaker housing 2 × 10" LF drivers and a 1.3" HF compression driver 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 Qi10 is a stand-alone full range loudspeaker system when used in the upright configuration and has a very accurate 110° horizontal constant directivity behaviour that is maintained down to approximately 800 Hz. The Qi10's wide constant directivity performance provides remarkable transparency when used in close proximity to listeners. It is also ideally suited to ambient and /or distributed sound reinforcement tasks where orientation within the sound field is critical. The performance differs considerably when the cabinet is deployed horizontally with the horn rotated by 90°. In this configuration the horizontal dispersion pattern is much narrower in the 500 Hz - 1 kHz region hence the use as a downfill in Qi1 arrays for example has limitations.
The Qi10 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 weather resistant (WR) version comes supplied with a fixed cable.

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 subwoofer 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 weather resistant (WR) version comes supplied with a fixed cable.

The QiCSA-SUB is a specifically designed version of the Qi-SUB for use as the rear facing element in Cardioid Subwoofer Arrays (CSA) only. It is acoustically compatible with the standard road version differing only in cabinet construction and mounting hardware. The QiCSA subwoofer 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 QiCSA-SUB cabinet is constructed from marine plywood and has an impact resistant paint finish. The loudspeaker cabinet has replaceable acoustically transparent foams fitted to both the front and rear sides of the cabinet, which are then protected by rigid metal grills. 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 and QiCSA-SUBs are stacked. The grill facing backwards is fitted with a single NL4 connector at the bottom left hand side. The weather resistant (WR) version is supplied with a fixed cable.
