Dolby Atmos Elevation Speaker Module: 

Definitive Technology designed the A90 elevation module as a dedicated height speaker designed specifically for the BP9060, BP9040, and BP9020 models so you can fully enjoy a Dolby Atmos multi-dimensional sound experience within your home theater setup. The A90 easily connects and sits within the top of the BP9000 speaker to fire sound upwards, which is then reflected off the ceiling and back down to your viewing area.



The Definitive Technology A90 Dolby Atmos elevation speaker module seamlessly integrates within the top of the following Definitive Technology BP9000 series tower speakers - BP9020, BP9040, & BP9060 (all sold separately). The A90 adds approximately 3.875" to the overall height of the BP 9000 series tower loudspeakers.


Proprietary, Plug-In Connector:


Two-Way Driver Design:

The Definitive Technology A90 Dolby Atmos elevation speaker module employs a two-way driver design with a 1" aluminum dome tweeter and a 4.5" midrange cone woofer. The speaker's crystal clear highs and detailed midrange bring the most demanding audio to life. Definitive Technology's tweeters play higher in frequency than what is heard by the human ear, creating an authentic reproduction of sound as the artist intends in the studio or concert hall.


Sloped Speaker Baffle: 

The Definitive Technology A90 Dolby Atmos elevation speaker module utilizes a sloped speaker baffle and exclusive foam construction to provide richness and depth to the sound. The Dolby Atmos elevation speaker module fires sound upwards, reflecting it off the ceiling and back down to your viewing area in a tightly controlled dispersion pattern, damping the sound that remains.


Resonance-Free Cabinet w/ Acoustically Transparent Grille: 

The Definitive Technology A90 uses a resonance-free cabinet w/ acoustically transparent grille for high performance sound. The speaker cabinet's maximum rigidity with strategically placed bracing improves imaging while reducing resonance, further reinforcing the speaker's clean and powerful sound. Thanks to the speaker's acoustically transparent grille, you'll enjoy the subtle elegance of the speaker design without having to remove a speaker grille to enjoy natural, uncolored sound.


Dolby Atmos:

 With Dolby Atmos, sound comes alive from all directions, including overhead, to fill the home theater with astonishing clarity, power, detail, and depth. Dolby Atmos is the first home theater system that is based not on channels, but on audio objects. Filmmakers using Dolby Atmos can decide exactly where those sounds should originate and precisely where they move as the scene develops. To deliver the full object-based soundtrack to home theaters, Dolby developed new home authoring tools and new encoding methods that allow all the audio objects created for the cinema to be used in home theater.

To experience Dolby Atmos using the Definitive Technology A90 elevation speaker module, you'll also need the following.

  • A minimum of a 5.1ch speaker system with a pair of Definitive Technology BP9000 series tower speakers (BP9020, BP9040, or BP9060).
