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, 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.
NOTE: The flow damping foam material mounted on the back of the DALI
PHANTOM H Series should not be removed. It will assist in managing bass/midrange
reproduction by damping resonances in the cavity behind the open-back woofer.
4.1 Mounting the dogleg brackets
DALI PHANTOM H Series incorporates dogleg brackets for 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 3). 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 the 3mm Allen key (enclosed in the package).
If using an Allen bit it 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 2.75”/70 mm thickness (see figure 4).
