4 Setting Up Speakers
• Setup on stands and mounting poles
General Information about Setting Up with Speaker Stands
Note! Always make sure the speaker stand is on solid footing and be sure
to observe the manufacturer's instructions as to its maximum load-bear-
ing capacity.
Take care!
• Use only speaker stands that are stable enough to prevent accidental tip-
ping. Ensure the speaker stand is designed to handle the cabinet's weight.
The highest setting on adjustable stands must be limited to prevent the
combination of speaker stand and speaker from tipping. This applies when
setting up the stand on a flat, horizontal surface.
• When setting up on an uneven or sloping surface, make sure the speaker
stand's base is secured to prevent accidental tipping, either by attach-
ing suitable weights to the base or taking other measures to secure the
stand.
• The use of any other fixtures or fittings can result in instability that may
cause injury.
• Setup with the Tilt-Unit
-0°
To ensure a safe setup directly on the subwoofers in a stacked configura-
tion, HK Audio offers the Tilt-Unit as an accessory which can be screwed
into the M20 mount of the LINEAR 5
pole. It secures the mid/high units from slipping.
setup without the Tilt-Units, the mid/high models must be secured
against slipping, e.g. with a lashing strap.

Deploy the LINEAR 5 118 Sub HPA as you would any other direct radiat-

ing subwoofer. However, when using in Cardioid mode, make sure that the
basses are not set up next to each other but on top of each other and that
there is at least 1 metre distance from walls.
You have two cardioid setups to choose from: Cardioid 1:1 and Cardioid 2:1
Select the proper presets for the given setup on the rear panel of the sub-

woofer. See section 2, 8 Preset for more on this.

The Cardioid presets attenuate the rearward sound pressure level by up to
34 dB, and boost the forward SPL by around 2 dB.

When does a Cardioid setup make sense?
While medium and high frequencies can be radiated in directional patterns,
low frequencies are spherical. This often leads to an unpleasant excess of
low bass on and behind the stage. Organisers are also increasingly setting
precise demands for sound distribution, for example in marquees in city
centres. The most effective way to achieve this in the bass range is with
Cardioid technology (cancelling out the frequencies radiated to the rear).
The 118 Sub HPA therefore meets all the requirements for quickly and easily
implementing effective cardioid setups, both mechanically and with the
available filter sets.
5 Example systems
For to ensure the most balanced image possible, centre the subwoofer
between the two mid/high units.

If you wish to place mid/high units
on speaker poles rather than stands,
simply screw a pole with an M20 thread
into the M20 pole mount on the LINEAR
