Patented Forward-Focused Bipolar Array (FFBP)

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

Integrated 8” 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. Definitive integrated powered subwoofer matched with its respective bass radiator offer deeper, more impactful bass from the tower speaker without the need to add a separate subwoofer.

Intelligent Bass Control

Intelligent Bass Control™ is their latest advancement that gives you the ability to modulate deep bass up or down in level while simultaneously maintaining mid-range tonal balance.

Dolby Atmos Certified & DTS:X Compatible

Definitive integrated a hidden connector port that fits our A90 speaker module seamlessly (sold separately). Simply remove the magnetically-sealed, acoustically treated aluminum top panel from the speaker and firmly align and place the A90 elevation speaker module within the top of your BP9000 speaker to hear and feel multi-dimensional sound (requires a Dolby Atmos/DTS:X-enabled receiver and Dolby Atmos/DTS:X-encoded source material).

Aluminum Dome Tweeters

Crystal clear highs bring the most demanding audio to life. Definitiv'es 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.

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.

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 the clean and powerful sound.

Cast Aluminum 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.

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.

LED Backlit Definitive Technology Logo

To highlight the integrated powered subwoofer and show that your speaker is receiving a signal, Definitive has added 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.
