Details & Highlights

Product Highlights

    We are bouncing off the ceiling with joy a?? just like the sound from the A90 by Definitive Technology. Home theater surround sound is no longer restricted to speakers around your head. The A90 sits on top of your Definitive Technology BP960, BP9040, and BP9020 speakers, firing sound up at the ceiling which reflects it back down to the listeners like a cathartic shower of high–fidelity tones that drench listeners in the purifying waters of soul–cleansing sound. To achieve this, the A90 boasts one 1–inch aluminum dome tweeter for clear, soaring highs, and one 4.5–inch mid–range driver. Both drivers are Dolby Atmos Certified and DTS:X compatible. A machined, aircraft–grade aluminum housing keeps high–performance components protected, while providing a sophisticated, yet understated, design.

    A90 High–Performance Height Speaker Module (Pair)

    The A90 height speaker module is the ideal solution for remarkable, immersive, room–filling sound that adds a level of detail and experience of pure home theater. The A90 supports Dolby Atmos / DTS:X and easily connects and sits within the top of your Definitive Technology BP9060, BP9040 and BP9020 speakers, firing sound upwards, which is then reflected off the ceiling and back down to your viewing area. Timeless, minimalist design. This is what obsession sounds like.

    Dolby Atmos Certified DTS:X Compatible

    Engineered to seamlessly integrate within the top of the BP9060, BP9040 and BP9020 speakers, the A90 can reveal greater sound height.

    Aluminum Dome Tweeters

    Crystal clear highs bring the most demanding audio to life. Our 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 with Exclusive Foam Construction

    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.

    Acoustically Transparent Grille

    Enjoy the subtle elegance of the speaker design without having to remove a speaker grille to enjoy natural, uncolored sound.

    Totally Inert, Resonance–Free Cabinet

    Maximum rigidity with strategically placed bracing improves imaging while reducing resonance, further reinforcing our clean and powerful sound.

    Minimalist Design, Timeless Appeal

    Powerful minimalist aesthetic with precision–machined components creates a sophisticated look to complement the most distinguished home theater. The sharp lines of the BP9000 Series also echo its precise sonic signature.
