Experience true immersive sound in your own home

The IC-6 OBA speaker is specifically designed to be used as the "elevation" component in an Object Based Audio system such as Dolby Atmos®, Auro 3D® and DTS:X® surround systems. The Atlantic Technology research and engineering team developed the IC-6 OBA to deliver the excitement of Object Based Audio encoded soundtracks with startling impact and holographic three-dimensional realism. The IC-6 OBA's frequency response and radiation pattern have been specifically engineered to provide wide dispersion to eliminate hot spots that occur with standard in-ceiling speakers.

Object Based Audio adds the essential characteristic that's been missing from the home theater experience- the sense of true audible three-dimensionality. The audio is mixed as audio "objects" instead of traditional channels. This means the content is not tied to any specific playback configuration. The technology also automatically adapts the object audio to take full advantage of the number and placement of your speakers, whether you have 2 speakers overhead or 10 speakers overhead. Additionally, the surround upmixer used in recently introduced A/V receivers and processors to allows for legacy channel-based content to be expanded to fill the flexible speaker layouts of an Object Based Audio system, providing a new dimension to older movies!

To best experience true object based audio, you need a speaker that is capable of creating the correct sound field. The original sound track has been mixed with a commercial movie theater in mind where sound is projected from a 30' height ceiling allowing the image to spread over a large area. This diffusion minimizes localization of the sound. Virtually all home theaters do not have the benefit of a 30' ceiling. Therefore, one needs a speaker that is capable of diffusing the sound thus eliminating any localization of "hot spotting" within the room. With its design, coupled with proper orientation in the installation, the IC-6 OBA  is an ideal choice to accomplish this acoustic goal.


Mica-Loaded Polypropylene cone: 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 tweeter: Another feature often found in the world’s finest loudspeakers. The low mass of treated cloth and its self-damping properties deliver more accurate sound with less distortion.

Stable tweeter bridge mounting: The tweeters in our ceiling loudspeakers are mounted on an extremely stable bridge rather than on a central “pole” as found in conventional 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.
