How Do These Speakers Work?

  • Each module features definitive's superb 4-1/2" mid/bass driver and 1" aluminum dome tweeter on the top of the speaker. 
  • These drivers are angled and feature controlled dispersion, so they can reflect sound off of your ceiling and back down to your listening positions. The a90 speakers attach to the top of the towers. 
  • Use a pair of a90s with your front towers, or add another pair to a set of rear surround towers for an even more enveloping experience.

Custom-built for the BP-9000 Series Powered Towers

  • The a90 speaker modules are a snap to install. Just remove the brushed aluminum cap on top of each tower speaker, and line up the speaker connector plug on the bottom of each a90 with the connector port on top of the tower.
  •  Gently push the a90s down, and you're ready for an intense home theater experience.

  • 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 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.
