Speaker Placement
Features
Polypropylene Cones
: Polypropylene has physical properties that
make it ideal for loudspeaker drivers and consequently is found in
many of the world’s finest loudspeakers. Its combination of stiffness
and strength-to-weight ratio means that it results in a more precise
and defined sound reproduction.
Soft-dome tweeters
: Another feature often found in the world’s fin-
est loudspeakers. The low mass of treated cloth and its self-damping
properties deliver more accurate sound with less distortion.
Adjustable tweeters
: The tweeters in your Atlantic Technology loud-
speakers are mounted in an orbital socket and can be adjusted by gently
pressing on their edge. This adjustment allows for directing the sound
when the speaker may need to be offset from an ideal listening position
due to aesthetic or physical reasons.
Stable tweeter bridge mounting
: The tweeters in our ceiling loud-
speakers are mounted on an extremely stable bridge rather than on a
central pole as found in many other designs. This mounting method
is less prone to resonance and vibration than a central “pole” tweeter
mount, resulting in cleaner sound, especially at high listening levels..
Bipole/Dipole Switch (6.3 and 8.3 only)
: This switch allows these
dual-tweeter speakers to operate as highly-effective diffuse surround
speakers in a home-theater system when their tweeters are out of phase
in the “Dipole” position.
Cut-out template
: Atlantic Technology loudspeakers come with a cut-
out template to allow the installer to accurately measure the hole to be
cut out in the wall or ceiling surface resulting in an easier installation
process.
Pre-construction bracket
: All Atlantic Technology loudspeakers have
an optional plastic pre-construction bracket. Their use is optional, but
can be very helpful to the installation process at the time the plaster-
board is about to be attached to the wall/ceiling. Therefore they would
be used only during more extensive renovations and not when retro-
fitting the loudspeakers into an existing surface.
Paintable Grilles
: Your Atlantic Technology loudspeakers come with
steel grilles pre-painted in white. These may be painted if required.
Important: Please refer to the section later in this manual on painting
grilles before you attempt any painting.
Angled Woofer (6 HT only)
: The woofer in the IC-6 HT is mounted
in an angled housing for precise coverage of the listening area.
High Frequency Switch (6 HT only)
: The IC-6 HT loudspeaker is fitted
with a high frequency (tweeter) switch. This enables you to adjust the
sound of the speaker to suit your personal listening preferences and
the acoustics of the room in which you are installing them.
Boundary Compensation Switch (6 HT only)
: The IC-6 HT has a
Boundary Compensation switch that compensates for the unwanted
added mid-bass response that results when a ceiling speaker is mounted
very close (within a foot or so) to a nearby wall (“Boundary”). Engaging
this switch “on” returns the speaker’s response to normal and improves
the sound.
Speaker Placement
The pivoting tweeters in Atlantic Technology loudspeakers are able to com-
pensate for unusual placements of the speakers themselves. However, the
ideal positioning of the speakers should be at roughly equal distances from
the intended listening area and along a common wall. This helps to ensure
the best stereo effect.
Naturally, intended listening positions are rarely static and they may vary
considerably within a room. In these circumstances, you can confidently
compromise on the ideal location and use the pivoting tweeter to assist
without impacting your listening pleasure.
2-Channel Audio Placement
In standard two channel audio systems, the ideal distance between the left
and right channel speakers should be in the range of 6-10 feet (1.8-3.0m)
apart. If the layout of the joists and light fittings permit, the speakers should
be equidistant from the most commonly used listening position.
To ensure the best stereo effect, place
speakers along a common wall, roughly equal
distances from the intended listening area.

Atlantic Technology ceiling loudspeakers feature swivelling tweeters to aim sound
directly at the listening area to compensate for offset mounting.
