you can install a fully edged 7.1 home theatre system.

The arrangement of speaker boxes follows the same
pattern as a 5.1 system. Please refer to “Speaker po-
sitions in the 5.1 conguration” on the previous two
pages.
Rear centre
In an ideal 7.1 system, the rear effects speakers (rear
sides) are positioned on the side walls facing the lis-
tening spot, and the rear centre speakers are po-
sitioned on the rear wall (height: 1.40–2.10 metres).
If the distance between the rear speakers and the
listening spot has to be less than 1.00 m, we recom-
mend using M 620 D dipole speakers instead of the
direct-radiating M 620 FCR speakers. In this case,
you would be better advised not to purchase a full
7.1 Cinema Set but a 5.1 Cinema Set with two addi-
tional M 620 D dipole rear speakers.
7.1 speaker placement: If you picture a top-view ge-
ometry of your surround setup, the four rear speak-
ers should ideally form an isosceles trapezium. Each
side of the trapezium should be at least 1.00 m long.
If the sides have differing lengths, or if the four rear
speakers are mounted at different heights, you can
compensate for such asymmetries by entering the
distances of the individual speakers in the AV re-
ceiver's “Speaker Management” utility.
We recommend
you place the rear speakers
somewhere in the grey rear
area.

Rear speaker placement option D Concert Set
Alternatively, position the left and right direct-ra-
diating rear speakers of the Concert Set behind the
main listening spot, ideally at the same height as the
front speakers – e.g., on a shelf or on speaker stands.
Higher speaker placement is ne, but avoid placing
the rear speakers down low. The rear speakers
should be positioned at least 1.00 m away from the
listener. If they are any closer, make sure that the
front of the speakers is not directly pointed at the
listener but into the room, angled slightly towards
the side walls. Alternatively, you can create the
necessary distance by positioning the speakers
higher than 1.20 m.
