Dali PHANTOM K Serie Manuel page 8

In a distributed sound system setup it is important, that the speakers are positioned
so that the main area of the room(s) is covered with sound (see chapter 4.4). To
achieve an even sound coverage, the speakers should be installed evenly in the
room(s) (see figure 3).
Objects positioned between the speaker and listening position might negatively
affect the sound quality. The PHANTOM E- and K-series are designed to meet our
wide dispersion sound principle. By using speakers with wide dispersion technology,
the distortion in the main listening area will be lowered and the room integration will
be better. The wide dispersion principle will also ensure that sound is spread evenly
within a large area in the listening room.
Every room has its own distinctive acoustics, which influence the way we experience
sound from a speaker. The sound you hear consists of both direct sound from the
speakers and reflected sound from the floor, ceiling and walls. The latter will affect
how you experience the sound. As a basic rule, try to avoid large, hard and reflective
areas in the immediate vicinity of your loudspeakers as it will typically cause strong
reflections, which might disturb the precision and spatial effect of the sound
reproduction. Soft items such as carpets, curtains etc. might help if the sound is
too bright.
Both the amount and quality of the deep bass depend on the size and shape of the
room, and the position of the speakers. Positioning the speakers near a side or
back wall will accentuate the bass. A corner location will accentuate it even more,
but will also increase the reflections.
4.1 Mounting the dogleg brackets
DALI PHANTOM E- and K-series incorporate dogleg brackets for ceiling/wall
mounting. The brackets attach the loudspeaker firmly to the rear of the surface
on which it is mounted. The dogleg brackets extend out at a 90-degree angle when
the screws are tightened (see figure 4). The screws should be tightened so that the
loudspeaker sits securely in place – but be careful not to over tighten the screws.
To tighten the screws, use a 3 mm Allen bit. The Allen bit should be used with a hand
bit screwdriver or a drilling machine with build-in torque setting. If using a drilling
machine, set the torque to the minimum setting. The screws are appropriately
tightened, when the gasket on the rear of the speaker is compressed and the bezel
of the speaker is flush with the mounting surface.
If you need to remove the loudspeaker, loosen the screws approximately 5 to 20
turns counter clockwise and the brackets will loosen their grip. NOTE: do not
unscrew more than 20 to 25 turns or the brackets may fall off the screws.
If you are mounting the loudspeaker in very thick wall material, it might be needed
to dismount the dogleg brackets from the screws and afterwards mounting them
upside down. Opposite mounting of the doglegs will make it possible to mount the
loudspeaker in boards with up to 2,55"/65 mm thickness (see figure 5).
