aligning the speakers horizontally. By turning the speaker, the sound can be
focused on the listening area.

When using the LINEAR 5
308 LTA on speaker stands or mounting
MK II
poles, it is not necessary to angle the speaker on the vertical axis. The MCT
horn gives a vertical dispersion pattern similar to the curving of a properly
set up component array. The sound energy is thus concentrated directly on
the area to be covered.
If the speaker cabinet is arranged vertically (baffl e 90° to the installation
surface):
• Although the speaker fl ange is designed for 0°, the vertical dispersion
angle is +5°/-25°.
• The vertical acoustic centre axis is about -3°.
• Ceiling refl ections are massively reduced due to this asymmetrical disper-
sion.

• The height of the speaker cabinet therefore defi nes the range. As a guide-
line: If the centre of the speaker cabinet is at a height between 2.50 m
(Fig. 3) and 2.80 m (Fig. 4), the central axis hits the ears of the listeners
after 15.50 m – 21 m for a person measuring 1.70 m tall.
• In rigging operations, horizontal and vertical alignment should preferably
be achieved using the optionally available tilt bracket. Rigging the speaker
cabinet allows for greater range and sound distribution over a larger area.
Headstack
Due to the asymmetrical dispersion of the MCT horn, the LINEAR 5
LTA makes it possible to operate two speakers acoustically correctly as a
"vertical headstack". In this scenario, the two speakers are coupled and the
sound energy is bundled. This results in a vertical dispersion of +10°/-10°
and a signifi cant increase in the sound coverage depth. If a greater sound
coverage depth is required, the headstack version is recommended. To do
this, the second speaker is rotated by 180° with its top plate placed on the
top plate of the fi rst speaker (the upper speaker is then "upside down" and
the front grilles of both speakers are facing forward) (Fig. 5)

Headstack
Due to the asymmetrical arrangement of three feet and corresponding
milled grooves in the speaker top plates, the two speakers stand on top
of each other in a way that prevents them from twisting and shifting. The
cabinets are then secured against being pulled apart vertically by using the
two sliding plates on the left and right sides of the speaker.
