Mounting Specifi cations
These speakers are intended for mounting in a ceiling, in material rang-
ing from 0.5 inches to 1 inch thick. They require at least 4-3/8 inches
for the ICTS-6.3 and 4-7/8 inches for the ICTS-8.3 clearance behind the
front sur face of the ceiling. The mounting opening for the ICTS-6.3 is
7-7/8 inches in diameter. The mount ing opening for the ICTS-8.3 is 9-5/8
inch es in di am e ter. These speakers will work equally as well in a wall as
in a ceiling, however note that they re quire more mounting depth than
is normal in a 2x4 studded wall.

Operating Modes and Locations
Mono Mode Use Mono mode when the speaker will play a single
chan nel of information (as
chan nel of information (as
either the left or right channel of a stereo pair
of speak ers). When used in Mono mode, both tweeters reproduce the same
signal. In Mono mode the speaker can be located anywhere within the
listening area. Generally however, it’s best to keep it at least 24 inches away
from any wall boundaries (ceiling/wall/corner). Placing any speak er in close
proximity to other boundary surfaces will always “col or” the sound that the
speaker produces. Even speakers that incorporate frequency ad just ments to
compensate can only make small im prove ments to the det ri men tal effects
of boundary refl ections. The more di rect ly under the speak er you are, the
more high frequency information you will hear. Should you be using two
speakers in Mono mode to re pro duce stereo, consider where the majority

speakers where the lis ten ers will get a
reasonable balance of sound from both
speakers. When wired in Mono mode
the tweeters interact strongly, chang-

Important Note: DO NOT rotate
the tweeter assembly or damage
will occur. To achieve the desired
dispersion pattern, rotate the entire
speaker assembly before mounting.
This can and should be used to your
advantage by rotating the speakers
when you install them in order to
properly align the tweeters. This way
you can exert some control over the
advantage by rotating the speakers
when you install them in order to
properly align the tweeters. This way
you can exert some control over the
spread of mid and high frequency sound throughout the room and hence
improve the sys tem’s per for mance.
Stereo Mode In Stereo mode each of the woofer’s dual voice coils and
the tweeters receives their own signals. The result is stereo re pro duc tion
(al be it with limited separation) from a single speaker. This is particularly
advantageous in distributed audio systems where there is a desire to have
stereo sound in many rooms, but with as few speakers as possible. Unlike
so many ceiling speakers, the ICTS-8.3 and ICTS-6.3 use very high quality
com po nent parts and sophisticated designs to deliver ex cel lent sound
quality; sound quality so good that it will surprise you. When installed
as a single point stereo speaker it’s typically best to lo cate the speaker
as centrally within the listening area as possible. Di rect ly in the center
of the room, or in the middle of the prime seating area.

TriVector
™
Surround Mode TriVector mode puts the two tweet-
ers in each speaker out of phase with each other. The result, when you
sit cen tered on the tweeter array, is a non-localizable sound fi eld that
helps re-create the surround fi eld intended by the movie’s director.
Since the goal of Home Theater is to get you “lost in the mov ie,” a
diffuse surround fi eld almost always works best. To that end the ideal
location for most diffuse surround speakers is directly to the sides of
the prime listening area. However, in many rooms there’s simply no
place to conveniently place speakers to the sides. Until the introduction
of At lan tic’s TriVector ceiling surrounds, the ceiling was an often used,
but generally less than ideal alternative.
When used in TriVector mode these speakers are best placed in the
ceiling to the sides of the prime listening location, with the tweeters
aimed towards the front and back of the room. You can also place the
speakers to the side and slightly forward or back of the prime listening
position, keeping the tweeter orientation as noted above. There’s a 15
degree “window” of place ment forward or back of the listening po si tion
that is ac cept able. But note that any more forward or back and you’ll lose
the diffuse effect. Also note that, due to the low midrange fre quen cies
com ing from the woofer, if you place the speakers directly over the
listening position there will be a fair amount of localizable surround
sound even when the speakers are set to TriVector mode.
