Explore a New Dimension of Sound

The BP9040 tower speaker system is your answer for remarkable, immersive, room-filling sound so you can experience every detail of pure home theatre. Forward Focused Bipolar Array expands your room’s entire soundstage. Aluminium dome tweeters, high-performance drivers, integrated powered subwoofer and Intelligent Bass Control let you hear and feel every note as the artist intends. Dolby Atmos / DTS:X compatibility let you explore true multi-dimensional sound. Timeless, minimalist design. This is what obsession sounds like.


BDSS – Balanced Double Surround System

Improves driver excursion which results in the selected driver producing bass output usually associated with a larger driver, while retaining the improved dispersion and midrange definition of a smaller driver.


Patented Forward-Focused Bipolar Array

Forward Focused Bipolar Array offers the ultimate balance between room-filling sound and a precise centre image while giving you total placement flexibility.


Integrated Powered Subwoofer and Dual Bass Radiators

The best loudspeaker is one that reproduces balance between the highest highs down to ground-shaking lows as accurately as possible. The BP9040's integrated powered subwoofer matched with its respective bass radiator offers deeper, more impactful bass from the tower speaker without the need to add a subwoofer.


Intelligent Bass Control

Definitive Technology's latest advancement gives you the ability to modulate deep bass up or down in level while simultaneously maintaining mid-range tonal balance


Aluminium Dome Tweeters

Crystal clear highs 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.

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 Definitive Technology's dedication to producing clean and powerful sound.

Cast Aluminium Base with Spikes and Floor Glides

The wide footprint increases overall stability of the tower speaker, while the addition of spikes or floor glides help keep your speakers firmly in place whether on carpet or other solid floor surfaces like hardwood or cement.

LED Backlit Definitive Technology Logo

To highlight the integrated powered subwoofer and show that your speaker is receiving a signal, you'll find an LED logo at its bottom front panel. Turn it on or off at your leisure and also note that it will automatically turn off/standby after 20 minutes of no active signal.

Dolby Atmos® and DTS:X® Compatibility

All BP9000 floor speakers offer Dolby Atmos or DTS:X compatibility. The BP9040 offers a hidden, dedicated connector port (fits A90 speaker module— sold separately) that can be accessed by gently pushing down on the back of the magnetically-sealed, acoustically-treated aluminium top panel. Regardless of your setup, simply run additional speaker wire to the height channel binding posts on the back of the loudspeaker from any Dolby Atmos or DTS:X compatible set-up.
