QSC GP212-sw User manual

GP212-sw
WideLine™ Ground-Support Subwoofer
The GP212-sw is a premium, high-
performance, rectangular dual 12" 4th
order band-pass subwoofer designed for
ground stacked use in touring or installed
concert applications where space constraints
or enclosure size are an issue. With an
impressive combination of punch, low-
frequency extension and musical accuracy,
the GP212-sw is an ideal companion for
QSC’s acclaimed WideLine series as well
as other professional sound reinforcement
systems.
For suspension in permanent installations
each GP212-sw subwoofer comes with a
total of six (6) threaded M10 inserts.
For ground-supported applications, the
subwoofers may be stacked horizontally using
their interlocking feet and recess features
machined into the enclosure’s top panel. A
screw-in (M20) pole mount has been added
to provide flexibility in use with small 2-way
pole mount full-range speakers.
The extremely musical yet powerful
performance of the subwoofer is the result of
carefully balancing the transducer selection,
cabinet volume and port tuning. The resulting
system offers plenty of “punch” while
maintaining ample extension so the musically
important and satisfying fundamentals are
solidly and accurately reproduced.
The enclosure of the GP212-sw is constructed
of premium quality birch plywood finished
in an environmentally friendly, waterborne,
polymer finish that stands up to life on
the road while also being field repairable.
Extensive internal bracing is employed to
eliminate acoustic losses due to panel
resonance. Further contributions to cabinet
rigidity come from vent walls constructed of
the same plywood as the enclosure.
Despite the extremely large amount of air
moving in the ports, careful attention to
detail has resulted in a system that is free
of port distortion “chuffing.” Ample port area
allows massive amounts of air to move freely
with minimal turbulence.
Like its “flyable” brother, the WL212-sw, the
GP212-sw subwoofer’s sonic performance
and output capacity to size ratio are second
to none. For those who only need the
exceptional sonic performance, without
the need for expensive rigging and flying
capability – the GP212-sw gives the exact
same sonic impact as the WL212-sw, but for
a more economical price tag.
QSControl.net™/ BASIS™ & SC28 DSP files
are available for download. They have been
fine tuned for use with the GP212-sw
and the WL212-sw to provide optimized
performance right out of the box.
