Applications
The K Series has been primarily designed for portable audio reinforce-
ment. This includes a variety of uses in reinforcement for entertainers
and presenters. The K8, K10 and K12 are all designed to perform well on
their own in full-range audio. They can be used singly, in stereo pairs or
in distributed or delayed systems. They perform extraordinarily well as
both main reinforcement systems and as floor monitors (K10 and K12
only). (Figure 1)
The K8, K10, and K12 are all equipped with a 35 mm pole socket that
allows use on a speaker stand or on a pole over a subwoofer. The pole
socket features the QSC Tilt-Direct™ system for tilting the enclosures
down 7.5 degrees while on the pole. (Figure 2)
The K8, K10 and K12 also have features designed for various suspen-
sion methods. They feature M10 threaded inserts for suspension with
eyebolts. There are also yoke accessories (model numbers: K8 YOKE,
K10 YOKE, K12 YOKE) for each model that can mount either to the sides
of the cabinet or to the top and bottom. These yokes allow for rigid
mounting to structures and rotation of the speaker system. (Figure 3)
For extra low-frequency extension and enhancement, the KSub is per-
fectly matched to the rest of the K Series. The K8, K10 and K12 all have a
selectable high-pass filter for use with the subwoofer. The KSub includes
a fixed low-pass filter so it will accept full-range input.
The KSub has four large casters for maximum portability. The pole sock-
et on the top of the enclosure is fitted with an M20 threaded insert. The
included speaker pole screws into the socket for a secure fit. (Figure 4)
