4.1 The Stereo Triangle
If the loudspeaker is going to be used for stereo
applications, the optimum listening position should be at
the top of an imaginary equilateral triangle with the two
loudspeakers should be placed at the other two points
of this triangle. The loudspeakers should be aligned with
the listener’s position.
4.2 Surround Placement
Speaker positioning for multi-channel stereo purposes is ideally based on a circle
with speakers placed at 0° (Center), 30° (Front Right), 110° (Rear Right), 250°
(Rear Left), 330° (Front Left), with the listener being the circle’s center (Radius
between 0.7-2.0 m). This ITU recommended configuration may vary for music or
film applications. However, it is recommended to create a symmetrical listening
position with the front side and surround speaker pointing to the listener’s ear.
The distance to the surrounding walls should be at least 40 cm to avoid early
reflections, which can degrade the sound.
4.3 Horizontal setup of the GTC 77 + GTC 88
For a horizontal setup one of the subwoofer
segments and the tweeter-/midrange segment of
the GTC 77 + GTC 88 are interchangeable. In this
way you can place the tweeter-/midrange
segment between the two subwoofers and also be able to rotate it through 90°,
allowing the easy and efficient adjustment of the tweeter according to the position
of the audience.
a) Put the loudspeaker rear side down on a soft surface and
unscrew the subwoofer segment (middle segment) and the
tweeter-/midrange segment. Lift the middle segment out of
the speaker housing, remove the foam mat from the bottom
of the chamber and unplug the underlieing cable connectors.
b) Lead the subwoofer cable from the middle chamber into the
upper chamber, then lift the tweeter-/midrange segment out
of the upper chamber.
