It's hard to beat the spacious sound of bipolar speakers, especially when you use a pair of Definitive Technology's BP-9020 high-performance towers in the front of your room. The BP-9020 uses a special driver layout with both front- and rear-firing speaker arrays to radiate sound in all directions. It also adds a built-in powered subwoofer to the bottom of the cabinet for intense bass. Even in large rooms, every listener will experience a huge, three-dimensional soundstage with both music and movies. Plus, this speaker's sleek, modern look and cloth grille-wrapped enclosure make it a welcome addition to just about any space.

High-tech towers for engaging music and home theater

Bipolar speaker technology immerses you in detailed sound

sound waves

Front and rear speaker arrays work together to create enveloping sound.

Here's how it works: direct sound from the front two midrange drivers and tweeter arrives at your ears first, to provide clear, focused imaging. That's followed by sound from the rear mid driver to enhance spaciousness. The combination creates a lush, seamless soundstage that's more like the way we hear sounds in real life. And thanks to Definitive's Balanced Double Surround System (BDSS) drivers, your music and surround effects will sound clear and accurate, allowing you to pinpoint the soloist in a band or the direction of a jaguar's call in the jungle.

Powerful bass built right in

At the base of the speaker is an 8" side-firing subwoofer, powered by a built-in 150-watt amplifier. It delivers deep, precise bass that eliminates the need for an external sub. And because a subwoofer is built into the cabinet, bass output is already perfectly blended with the mids and the highs. All you have to do is set the bass volume to match your room and taste, then sit back and enjoy your music and movie soundtracks.

Dolby Atmos® ready

If you're looking for an easy way to seamlessly integrate Dolby Atmos surround sound into your home theater, the BP-9020 is ready to go. Underneath this tower's handsome, removable aluminum top plate is a built-in docking port made exclusively for Definitive's optional A90 Atmos enabled speaker module.

Simply remove the plate, attach the A90 module to the port, and you're ready for an intense home theater experience. The hidden integrated connector port terminates at the base of the tower with a pair of binding post speaker terminals for connection to your Dolby Atmos compatible receiver's "Height" or "Top" outputs.

Build a complete Definitive Bipolar home theater system using perfectly matched centers (see the CS-9040, CS-9060, and CS-9080) and bipolar surrounds (see the SR-9040 and SR-9080).

Did you know?

Your new speakers will probably sound better after several weeks of use than they do right out of the box. That's because the material surrounding the woofers will loosen up, allowing the drivers to move more fully. Definitive Technology estimates a break-in period of 24 to 48 hours of playback before the speakers will deliver optimum sound quality.

Great speakers and the best price anywhere. Speakers shipped out very quick. Arrived in perfect condition. They are very versatile when it comes to sound. You can add an external base module to your setup, but isn't absolutely necessary. You will surprised at the amount of base these things produce.

Crutchfield Customer Review (What's this?)

the speakers sounds great. I really like it as it has subwoofer built in which fill out the surround sound in my living as I've matched it with two Klipsch 12" subwoofer center speaker and two R-82IIs. just need to run room correction. Plus the DT was on sale made my decision easier.



Love them! Buy them!

Sara from Basking Ridge, NJ on 11/25/2018

Crutchfield Customer Review (What's this?)

With these speakers I have no need to add a subwoofer. We use them for music and watching tv and the sound is EXCELLENT. Loads of power, rarely running at more than 50 volume. Great detail in the mids and highs and the lower frequencies are clean and powerful. Love that they don't take up a lot of space, and while I'd love a cherry cabinet (we have an 1800s home) these still look great.



Buy them!!

Come on man, These speakers are incredible...

Pros: They are really powerful

Cons: They embarrass my 8000 series speakers

beautiful clear sound across the sound range

Stan from St. Thomas, VI on 9/16/2018

Crutchfield Customer Review (What's this?)

The cornerstones of my new 5.2 (or thanks to a y-splitter, 5.3) surround system. These two beauties paired with a CS-9060 center speaker and two 9040 rear speakers, which I was finally able to set up yesterday on my Denon AVR-X3400H receiver, now make sports (Dish and streaming), movies (blu-ray and streaming), and TV (using a Dish DVR) come alive. The two speakers were a snap to set up.. install the beautifully engineered base using the four supplied screws, installed the four flat floor mounts (included in addition, were four carpet spikes in case you have floor carpeting .... plug in, connect two cables, one for the channels and one for the LFE to the AVR, and voila.... some of the clearest dialog outside of a movie theater i have heard. Watched a CBS college game yesterday and it was like I was at the game... center, fronts and rears working in extreme harmony (no pun intended). I truly now understand why everyone says you need timbre matched speakers as part of a system.

Pros: clear dialog clear separation throughout the sound spectral range extremely well packaged... arrived US Mail with no damage whatsoever

Cons: None as of yet

Beautiful Sound across the board

Sara from Basking Ridge, NJ on 8/26/2018

Crutchfield Customer Review (What's this?)

I absolutely love these speakers! Wanted to get away from needing a separate sub woofer, and these speakers deliver. Sleek in the room, no distortion, details in the mid-range are great too. Highly recommend!

Pros: Excellent sound without needing separate sub-woofer

Cons: would have loved other cabinet option colors, but basic black is fine.

Just Plain Great Speakers

Crutchfield Customer Review (What's this?)

Only had them for a couple of weeks, but they sound terrific...and fill up our 2500 cubic feet of media room with glorious sound! Paired with the Def Tech ProCenter 2000 up front...great combo.

Great products, I just love the sound and the built in powered subwoofer



Great speakers from Def Tech

Easwar from Parlin, NJ on 11/27/2017

Crutchfield Customer Review (What's this?)

Great set of speakers that replaced Bose Acoustimass. I am using the BP-9020 with the CS-9040 and SR-9040 amplified by Yamaha RX-A870 and I have found this combination to be excellent. I am looking to add the A90 (Dolby Atmos) height speakers in the near future. So far I am impressed with the performance of the speakers and I am very happy with the suggestions provided by Crutchfield advisors Mick and Norm. With their suggestions, I was able to put together a great system for my home. Highly recommend these speakers and Crutchfield's service and ease of ordering. Great team!!!

Pros: Good bass and good looking speakers

Cons: Fabric finish on the speakers feel a bit light to the touch.

Crutchfield Customer Review (What's this?)

Finally decided to upgrade my fronts, after some research I decided to give these a try and I could not be happier. They are a perfect addition to my home theater system. The sound is awesome and they look good.

Pros: Great Bass output Perfect fit for my Pioneer Elite 90 VSX.

Cons: none yet

Dan from Minneapolis, MN on 1/3/2017

Crutchfield Customer Review (What's this?)

Bought BP9020's after researching comparable floorstanding models for 4 months. Bipolar design and adjustable, built-in subwoofers are a great fit for my 18' x 45' room. Sound is natural and clarity is excellent. I plan to add more Def. Tech. components in the future.

Pros: Small footprint, clean look, bipolar design, atmos speaker capabilities, great sound

Cons: Small washers for base fasteners could be beneficial

Definitive Technologu speakers

Nic. from Ft Myers, FL on 10/2/2016

Crutchfield Customer Review (What's this?)

Needed new speakers after my 30 yr old Missions started to die. Looked at Cambridge and Klips. Called Eddie and as we live in a Florida house with a great room he recommended the Definitive Technology as they would fill the room and boy was he right. There is no single sweat spot, just great quality sound all around the room. I love the powered base that gives so much depth to the sound. Overall so much better than my very old, but very expensive speakers. Technology has come a long way. Highly recommend them.

Pros: Quality of sound. Clarity works well with my Denon and plenty of power. High and mid range are good. Need to work on the low range sound

Cons: They look very good. Not sure about fabric finish on all sides, especially if you have a hyper cat.

Tower Loudspeaker: The Definitive Technology BP9020 tower speaker is the answer for remarkable, immersive, room-filling sound so you can experience every detail of your home theater soundtrack. Its patented Forward Focused Bipolar Array (FFBP) will expand your room's entire soundstage for an enveloping sound. An aluminum dome tweeter, high-performance midrange/midbass drivers, and an integrated powered subwoofer with Intelligent Bass Control let you hear and feel every note as the artist intended.

Forward-Focused Bipolar Array (FFBP): The Definitive Technology BP9020 tower speaker utilizes powerful, Forward-Focused Bipolar (FFBP) speaker array for wide and immersive sound dispersion. Forward Focused Bipolar (FFBP) Array offers the ultimate balance between room-filling sound and a precise center image, while giving you total placement flexibility. The FFBP array consists of a 1" aluminum dome tweeter and two 3.5" midrange/midbass cone woofers on the front and one 3.5" midrange driver on the back. By radiating sound both forward and rearward, the speaker produces sound as it is in real life, with improved pinpoint localization of soloists, greater placement flexibility, and superior intelligibility.

Aluminum Dome Tweeter: The BP9020 tower loudspeaker features one 1" aluminum dome tweeter for crystal clear highs that bring the most demanding audio soundtracks to life. The Definitive Technology tweeter is designed to 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 (2nd Gen) Drivers: The Definitive Technology BP9020 employs three 3.5" midrange/midbass cone woofers (two on front/one on back) with patented Balanced Double Surround System (BDSS) technology (2nd generation). BDSS technology 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.

Integrated Powered Subwoofer: The BP9020 contains a integrated powered subwoofer that consists of a side-firing 8" woofer and 150 watt amplifier designed to extend the frequency response and dynamic range of the tower speaker. The best loudspeaker is one that reproduces balance between the highest highs down to deepest lows as accurately as possible. The integrated powered subwoofer offers deeper, more impactful bass from the tower speaker without the need to add a separate powered sub. The benefits of a built-in subwoofer include -

  • Eliminates the need for a separate subwoofer that takes up additional floor space.
  • More bass output from two subwoofers, compared to one.
  • Two subwoofers reduce standing wave room resonances and dead zones.
  • The subwoofers are perfectly integrated and blended with the mids and highs, eliminating the crossover and phase controls of a separate subwoofer.

Intelligent Bass Control: Intelligent Bass Control is Definitive Technology's latest advancement that offers enhanced bass while maintaining overall mid-range tonal balance. Intelligent Bass Control gives you the ability to modulate deep bass up or down in level while simultaneously maintaining optimal mid-range clarity regardless of where the bass control is set. Simply rotate the dial on the back of the loudspeaker to your preferred bass setting and the speaker will do the rest. Definitive Technology recommends starting at the mid-point and then adjust to your preference from there.

Bass Port: The BP9020 tower loudspeaker utilizes a rear-firing slot sport for higher efficiency and deeper bass.

Acoustically Transparent, Resonance-Free Cabinet: The Definitive Technology BP9020 uses a resonance-free, one-piece cabinet for high performance, distortion-free sound. The speaker cabinet's maximum rigidity with strategically placed bracing improves imaging while reducing resonance, further reinforcing the speaker's clean and powerful sound. The BP9020 loudspeaker's cabinet is wrapped in an acoustically transparent cloth grille for unaltered sound. Thanks to the speaker's acoustically transparent grille, you'll enjoy the subtle elegance of the speaker design without having to remove a speaker grille to enjoy natural, uncolored sound. On the top of the cabinet is a brushed aluminum, acoustically-treated magnetic plate that finishes off the speaker cabinet nicely.

Speaker & Line Level Inputs: The Definitive Technology BP9020 tower loudspeaker is fitted with both speaker-level (binding post) and line-level (LFE/mono-RCA) inputs.

  • Binding Post Terminals: The speaker terminals are 5-way binding posts that will accommodate spade connectors, single or dual banana plugs, pin-connectors, and bare wire up to 10 gauge. By connecting the tower speaker's binding post terminals to your AV receiver's front speaker terminal outputs, the BP9020's internal crossover network distributes all frequencies to their intended drivers, and the integrated subwoofer works harmoniously with the mid-range array. In your AV receiver's menu, set the Front speakers to "Large" and Subwoofer to "No". 
  • LFE/mono-RCA Input: For those you demand greater customization, the BP9020 also features an LFE/mono-RCA input. In this setup, your AV receiver's front speaker outputs still connect to the BP9020's binding post speaker terminals, but also requires that the AV receiver's LFE/mono-RCA output to be connected to the tower speaker's LFE/mono-RCA input. This type of setup gives you the ability to control the amount of low frequencies (those below the crossover point set in your receiver) sent to the integrated subwoofer. You will need to set front speakers to "Small", subwoofer to "Yes", and the crossover point in your AV receiver to 80Hz or below to avoid disturbing the delicate blending between the subwoofer and midrange. In addition, careful balance between the subwoofer output level of your receiver and the bass control on the back of your speaker should be considered (Definitive Technology recommends starting with the bass control at 12 o'clock).
Note: Definitive Technology recommends that you do not use your receiver's auto setup functions, as they can be ineffective in setting up and adjusting speakers with integrated powered subwoofers. Configure tower speaker into your home theater system using your AV receiver's manual setup menu.

Cast Aluminum Base w/ Interchangeable Feet: The BP9020 tower loudspeaker is supported by a sturdy, cast aluminum base. The cast aluminum base's 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 tile. The floor glides add approximately 0.4375" to the overall height of the tower speaker, while the spike feet add approximately 1" to the overall height of the speaker.

Note: The tower speaker must be used with the cast aluminum base for maximum stability.

Placement: The BP9020 tower speaker offers bipolar sound, meaning they will reflect sound off the back and side walls to create an incredibly broad and engaging soundstage no matter where you sit. The BP9020 tower loudspeaker is very flexible in terms of positioning and placement. To optimize performance, please follow these simple placement guidelines -

  • Setup a pair of tower loudspeakers and the main listening position in an equilateral triangle for the best stereo imaging.
  • Position each tower speaker at least 4" away from the back wall to maximize its bipolar sound.
  • Toeing the tower speakers in slightly, if possible, toward your viewing area will also provide a stronger center image.

AC Power: Because the BP9020 features a built-in powered subwoofer, you will need to connect the tower speaker to an AC outlet. The tower speaker's built-in amplifier will automatically turn-on once it's receiving an active signal from your AV receiver, and will automatically turn off after 20 minutes of no active signal.

Front-Panel LED: There is a front-panel LED "D" logo which illuminates when the BP9020's built-in amplifier is on, and turns off when the built-in amp is in standby mode. The LED "D" logo can be deactivated entirely.

Optional Dolby Atmos Elevation Module: The BP9020 features an integrated, hidden connector port that fits Definitive Technology's A90 Dolby Atmos elevation speaker module (sold separately) seamlessly. Simply remove the magnetically-sealed, acoustically treated aluminum top panel from the BP9020 tower speaker and firmly align and place the A90 elevation speaker module within the top of  the tower speaker to hear and feel Dolby Atmos multi-dimensional sound. There are dedicated binding post terminals (labeled "Height") to connect the "Height" channels of your AV receiver to the BP9020.You will also need a Dolby Atmos-enabled receiver and Dolby Atmos-encoded source material.

BP9000 Series: The BP9020 is part of Definitive Technology's BP9000 series line-up of speakers. Definitive Technology's BP9000 series loudspeakers is its 4th generation of bipolar tower speakers, matching center channels, surrounds, and a height speaker module, designed to offer true, full-range performance for listeners seeking the highest quality audio reproduction. The BP9000 series of loudspeakers consists of the BP9020, BP9040, BP9060 and BP9080X bipolar tower speakers; the CS9040, CS9060 and CS9080 center-channel speakers; the SR9040 and SR9080 surround speakers; and the A90 elevation speaker module supporting Dolby Atmos.
