Definitive Technology BP9040 Floorstanding Speakers – Pair

The Definitive Technology BP9040 Floor standing Speakers, immerse yourself in a new dimension of home theater sound that envelopes you in every detail. The BP9040 boasts integrated subwoofers, dual bass radiators, and our Forward Focused Bipolar Array (FFBA) to expand your room’s entire soundstage.

Show stopping Sound

Featuring unique technologies such as Forward Focused Bipolar Array (FFBA), Balanced Double Surround System™ (BDSS) drivers, integrated subwoofers, and passive bass radiators, BP9040 loudspeakers deliver extraordinary home cinema experiences.

Forward Focused Bipolar Array for stunning depth of field

The Definitive Technology BP9040 premier technology is our patented Forward-Focused Bipolar Array (FFBA). The BP9040 array incorporates three 4.5” midrange drivers (two front-facing/one rear-facing) and two 1” aluminum dome tweeters (front and rear-facing). By simultaneously firing both forward and backward, a naturalistic delay is added to the sound that creates a sense of immense depth in rooms of any size.

Built-in 8” Powered Subwoofer for room-shaking bass

The BP9040 includes a built-in powered 8” subwoofer, which results in more consistent bass throughout your room while eliminating the need to invest in a standalone subwoofer. Coupled with the BP9040’s dual passive bass radiators—which dramatically increase the speaker’s bass-producing surface area—you’ll feel impactful low end that you wouldn’t expect from floor standing speakers alone.

Balanced Double Surround System (BDSS™) for the best seat in the house

All mid/bass woofers in the Definitive Technology BP9040 feature our innovative Balanced Double Surround System™ (BDSS) technology which improves driver excursion. BDSS results in a wider, more uniform midrange soundstage throughout your listening environment and also enables the BP9040’s drivers to play lower and better blend with its built-in subwoofer. With a more consistent soundstage and detailed mids and lows, BDSS drivers ensure that with the BP9040, you’re always in the best seat in the house.

Aluminum Dome Tweeters for crystal clear highs

The BP9040’s Aluminum Dome Tweeters feature ultralight, rigid construction that enables them to play significantly higher frequencies than we can hear with incredibly fast and accurate transient response. This provides effortless, distortion-free performance within and beyond the audible range—perfect for the enjoyment of high resolution audio.

The Perfect Movie Night

It’s not just the massive sound stage, thunderous bass, and detailed drivers that make the Definitive Technology BP9040 an integral component in your home theater speaker system. The BP9040 also features Intelligent Bass Control, a disappearing design, and the ability to integrate a height module for a truly immersive and powerful 3D sound experience.

Intelligent Bass Control for punch with clarity

Intelligent Bass Control, a Definitive Technology exclusive, enables you to experience powerful deep bass performance from the BP9040 without sacrificing optimal midrange clarity. Intelligent Bass Control achieves this by utilizing 56-bit digital signal processing to allow boosting of the bottom two octaves of your signal without altering the bass-to-midbass blending and crossover point. Combined with BP9040’s resonance-free cabinets, Intelligent Bass Control ensures that your chosen bass level will never get in the way of dialogue or any other aspect of the soundtrack.

Disappearing Design for focus on what matters

The Definitive Technology BP9040 is wrapped in an acoustically transparent black cloth grille that won’t affect the sound. As soon as you dim the lights, they disappear into your room—so you can focus on the movie, not your speakers.

Dolby Atmos & DTS:X (BDSS™) for total immersion

Pair the BP9040 with the A90 Height Module to take full advantage of Dolby Atmos and DTS:X 3D audio. When you integrate the dramatic vertical dimension they provide with the stunning depth of field, wide soundstage, and deep bass offered by BP9040 you’ll enjoy games, music, and film with a full level of 3D sound immersion unlike anything you’ve ever experienced before.

Modern and Sleek

We understand that you make a statement with your choice of home theater components. The Definitive Technology BP9040 wasn’t just designed to sound sensational; they also make for a compelling yet understated visual presence in your home.

Versatile placement for complete flexibility

The wide footprint of the BP9040’s cast aluminum base 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.

Not Just for Home Cinema

All the advances that make the BP9000 Series the ultimate home cinema speaker system apply to beautiful music reproduction as well. That’s why the BP9000 Series is also revered for its extraordinary musicality—it’s like sitting with the mix engineer when watching concerts or music videos, or when listening to multichannel audio from FLAC, Blu-ray or SACD sources.
