Applications

The K.2 Series has been primarily designed for portable audio reinforcement.
This includes a variety of uses in reinforcement for entertainers and presenters.
All are 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
as shown in Figure 4.

All three models are equipped with two 35 mm pole sockets that allows use on
a speaker stand or on a pole over a subwoofer. (The subwoofer must have a
35 mm pole socket capable of supporting the loudspeakers.) One socket is for
vertical mounting, the other for tilting the enclosures down 7.5 degrees.
(RefertoFigure 5)

In addition, the K.2 Series have features designed for various suspension
methods. They feature two M10 threaded inserts for suspension with eyebolts
and a built-in pull-back ring. There are also yoke accessories (model numbers: K8.2 YOKE, K10.2 YOKE, K12.2 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. (Refer to Figure 6 andFigure 7)

Installation

WARNING!: Before placing, installing, rigging, or suspending any speaker product, inspect all hardware, suspension,
cabinets, transducers, brackets and associated equipment for damage. Any missing, corroded, deformed, or non-load rated
component could significantly reduce the strength of the installation or placement. Any such condition severely reduces the
safety of the installation and should be immediately corrected. Use only hardware which is rated for the loading conditions
of the installation and any possible short-term, unexpected overloading.

Never exceed the rating of the hardware or equipment.

Consult a licensed, professional engineer regarding physical equipment installation. Ensure that all local, state and national
regulations regarding the safety and operation of loudspeakers and related equipment are understood and adhered to.
