<strong>The</strong> <strong>Qi</strong>1 loudspeaker<br />
<strong>Qi</strong>1 loudspeaker<br />
<strong>The</strong> <strong>Qi</strong>1 is the installation version of the Q1 line array loudspeaker.<br />
It is acoustically compatible with the standard road version differing<br />
only in cabinet construction and mounting hardware.<br />
<strong>The</strong> <strong>Qi</strong>1 cabinet is a passive 2-way design that houses 2 x 10”<br />
LF drivers and a 1.3” HF compression driver with a toroidal wave<br />
shaping device to achieve a 75° x 15° (h x v) dispersion<br />
characteristic. <strong>The</strong> two 10” neodymium LF drivers are positioned<br />
in a dipolar arrangement providing an exceptional dispersion<br />
control even at lower frequencies with the 75° nominal dispersion<br />
angle being maintained down to 400 Hz.<br />
<strong>The</strong> <strong>Qi</strong>-SUB subwoofer extends the system frequency response<br />
to below 40 Hz, for further extension of bandwidth and headroom<br />
ground stacked B2 subwoofers can be used (driven in INFRA<br />
mode).<br />
<strong>The</strong> <strong>Qi</strong>1 cabinet is constructed from marine plywood and has an<br />
impact resistant paint finish. <strong>The</strong> front of the loudspeaker cabinet is<br />
covered with a replaceable acoustically transparent foam that is<br />
then protected by a rigid metal grill. Four M10 threaded inserts on<br />
each side panel of the cabinet enclosure are provided for attaching<br />
installation hardware. <strong>The</strong> cabinet rear panel is fitted with two NL4<br />
connectors wired in parallel. <strong>The</strong> weather resistant (WR) version<br />
comes supplied with a fixed cable.<br />
