Removing the Grilles
The included grilles are attached to the top of the enclosures with plastic
stems that are inserted into rubber grommets. If you wish to remove the
grille to view the speaker element, simply grasp the frame of the grille cover
and gently lift the grille out. To re-attach it, reverse the process by lining up
the plastic stems into their corresponding receptacles and push down on
the grille frame.

What is Dolby Atmos

What is Dolby Atmos?
Dolby Atmos® adds the essential characteristic that’s been missing from
the home theater experience: the sense of true audible three-dimensionality. Dolby Atmos-encoded movies deliver this experience, like no other
movie format can.
You’ll get a great immersive experience, no matter what kind of Dolby
Atmos home theater setup you have. Dolby Atmos content is mixed as audio
objects instead of traditional channels. This means the content is not tied to
any specific playback configuration. Further, the technology automatically
adapts the object audio to take full advantage of the number and placement of your speakers, from systems with five speakers on the floor and
two speakers producing overhead sound to a system with as many as 24
speakers on the floor and 10 speakers producing overhead sound.
Additionally, the new Dolby surround upmixer used in today’s A/V receivers
and Processors allows for legacy channel-based content that has not been
mixed for Dolby Atmos to be expanded to fill the flexible speaker layouts
of a Dolby Atmos system providing a new dimension to your old movies.
Description
The Atlantic Technology 44-DA speaker was specifically designed to be used
as the “elevation” component in a Dolby Atmos surround system.
Working closely with Dolby Laboratories, Atlantic Technology’s research
and engineering team developed the 44-DA with its unique vertically-firing
Concentric Driver Array (CDA™) to deliver the excitement and realism of
Dolby Atmos-encoded soundtracks with startling impact and holographic,
three-dimensional realism. The 44-DA’s frequency response and radiation
pattern have been specifically engineered to meet these requirements.
The 44-DA speaker itself embodies the same high quality components—such as its long-excursion damped polypropylene 5 ¼” woofer, 1”
silk-damped dome tweeter and optimized 1st-order Butterworth crossover—and meticulous attention to detail that are the hallmarks of all
Atlantic Technology products.
The speaker module is designed to fit perfectly on top of Atlantic Technology’s
THX- certified 4400 LR speakers, creating an integrated, “one-piece” look.
Additionally, because of their compact design and neutral appearance, the
44-DAs are well suited to being used on top of other speakers or, equally
important, as “stand-alone” Dolby Atmos enabled speakers as part of a
complete Dolby Atmos system.

Placement in a Dolby Atmos-enabled
System
The 44-DA delivers the “overhead” dimension in a Dolby Atmos-enabled
home theater system. The Dolby Atmos-enabled speakers are used in addition to the usual speakers in a 5.1 or larger home theater system.
The 44-DA speakers allow you to experience overhead sounds when the
speaker is placed at the same level as a traditional speaker. These Dolby
Atmos-enabled speakers direct sound upward to reflect off the ceiling,
as Figure 3 shows, to create a faithful reproduction of audio coming from
above.

VERY IMPORTANT:

Do not place anything on the cloth grille on the top of the speaker,
place the speaker in a cabinet or below a shelf. These situations will
obstruct the sound path, impairing the performance, and possibly
damaging the speaker elements beneath the cloth.
