B&W electronics dm70 Instruction Manual - page 12
Although in the case of the DM70 (due to its remarkable dispersion
characteristic) positioning is not as critical as w i t h many conventional
loudspeaker systems, this system is quite a substantial piece of
furniture in its o w n right, and it is worthwhile taking care in siting the
loudspeakers in the most acceptable positions, both visually and
acoustically.
It will be found that the stereo image is preserved over a wide listen-
ing angle, and the satisfactory listening area larger in the case of the
DM70 than w i t h most conventionally designed loudspeakers.
Example of sitings of a pair of DM70's and a pair of conventional
Loudspeakers are illustrated in figure 3.

A simple guide to siting.
1. It is suggested that in initial layout a flexible lead is used, and the
positions of the loudspeakers experimented w i t h on familiar music
until a natural balance is obtained. Permanent installation may
then be undertaken after the exact positions have been decided.
2. Bass response within the bottom t w o octaves will vary w i t h the
positions of the loudspeakers relative to any plane surfaces.
Minimum bass will occur in the unlikely event of the loudspeakers
being situated near the centre of a room. Conversely, maximum
bass response will result should the loudspeakers be tightly
" c o u p l e d " to the corners of the room.
