    Overview

    The simple, plain design of the BP9040 Tower Speaker allows it to merge seamlessly with your entertainment setup, just waiting for its moment to unleash glorious audio. These speakers utilise Definitive Technology’s patented Forward-Focused Bipolar Array which features key drivers mounted on the front and rear panels of the loudspeaker. The Bipolar Array maintains a precise centre image but also extends the soundstage meaning that the auditory sweet spot is wherever you happen to listen from.

    Delivering those rumbling bass tones time after time, the speakers make use of an integrated eight inch powered subwoofer. The Balanced Double Surround System utilises inner and outer rubber seals, which improve the excursion of the driver and increase the impact of the lower bass tones. Adding to this is the Intelligent Bass Control, letting you feel, as well as hear, the impact of every single powerful note.

    The interior of the cabinet has been built to be resonance free, by constructing it with maximum rigidity in mind, with additional strategic bracing to improve audio clarity. And with Dolby Atmos and DTS:X compatibility, it’s easy to enshroud yourself in immersive surround sound.
    Forward-Focused Bipolar Array

    Key audio drivers positioned on the front and back of this unit maximise the soundstage, for expansive audio. The FFBP also maintains a precise centre image ensuring that the sweet spot is wherever you listen from.

    Dolby Atmos

    Dolby Atmos technology creates a 360° audio field above and around you. Conventional home theatres shoot audio directly at you and that creates a two-dimensional sound experience. With Dolby Atmos, sound is multidimensional; it moves around you, fills the space around you, and truly immerses you in the scene.

    Balanced Double Surround System

    Making use of balanced inner and outer surrounds on the mid-bass drivers, this unit benefits from greater excursion, higher sound detail and punchier bass.

    DTS:X

    Providing a 3-dimensional sound experience and an alternative to Dolby Atmos, DTS:X flows sound around you for glorious audio immersion. Feel as if you were enveloped in an all-encompassing embrace of sound with DTS:X capable of mapping an unlimited number of audio ‘objects’ overhead.
