The A77X in a stereo setup

The A77X has been designed for a horizontal set up. Please note that for a stereo
setup consisting of two A77X monitors there are two different versions available,
A and B (see label on the rear panel). The reason for the A and B versions is that
although both 7" woofers are operating in the bass domain down to 38Hz, one
woofer is gradually faded out between 150Hz and 400Hz. This means that only one
woofer reproduces the actual midrange in order to prevent interferences between
the two drivers. For the best stereo image in a setup with two A77X it is vital to
place both speakers the A/B or the B/A way, meaning that both midrange woofers
should either face the inner side or both the outer side of the stereo setup mirror-
symmetrically. Should you wish to use the A77X as a center speaker in a surround
setup of course the A and B versioning is of no importance.
4.4 Tweeter at the height of ears
The Tweeter should be positioned approximately at the height of your ears. In
case you need to position the speaker in a significant lower or higher position, the
monitor should be angled accordingly.

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 to be placed at the other two
points of this triangle. The loudspeakers should be
aligned with the listener's position.
