Our take on the Definitive SR-9080

Definitive Technology's SR-9080 bipolar surround speakers will plunge you into a deep, atmospheric soundfield that lets you fully experience your TV shows and movie soundtracks. Designed to create an immersive listening environment, they feature left- and right-firing driver arrays that radiate full-range sound in an omni-directional pattern that really let you hear the difference as on-screen action shifts seamlessly from one side of the room to the other.

Playing in the deep end

Definitive Technology's SR-9080 bipolar surround speakers will plunge you into a deep, atmospheric soundfield that lets you fully experience your TV shows and movie soundtracks. Designed to create an immersive listening environment, they feature left- and right-firing driver arrays that radiate full-range sound in an omni-directional pattern that really let you hear the difference as on-screen action shifts seamlessly from one side of the room to the other. 

High-tech drivers for exceptionally detailed sound

Each driver array in the SR-9080 has a 4-1/2" mid/bass driver paired with a 1" dome tweeter, for perfectly blended highs and lows. The speaker's aluminum dome tweeter is heat-treated to relax the crystal structure of the metal, then attached to a silk surround to help produce smooth, sparkling highs that reveal delicate, low-level ambient details in soundtracks. And thanks to Definitive's Balanced Double Surround System (BDSS) driver design, your movie special effects and multichannel music will sound clear and detailed. These mid/woofers disperse the sound over a wide area in your room so that even viewers sitting off-axis hear engaging surround sound.

Versatile placement options

Definitive's bipolar surrounds aren't fussy about placement — they shine in a variety of room sizes and shapes. A pair of SR-9080s works well on your side walls for 5-channel systems, or on the side and rear walls for a 7-channel system. Each speaker has a keyhole slot for on-wall installations. You can also place this speaker on a shelf or stand and get great results.

Build a complete Definitive home theater system using perfectly matched bipole towers (see the BP-9020, BP-9040, BP-9060, and BP-9080X) and center channel speakers (see the CS-9040, CS-9060, and CS-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.

Perfect solution

Chad from Jackson Center, PA on 3/3/2019

Crutchfield Customer Review (What's this?)

Love these speakers. Used them in the back of my room (12'x18') for rear surrounds. Due to the size and layout of my room regular bookshelves for rear surrounds were too direct. I couldn't enjoy them unless i sat in just the right spot. The Definitive SR-9080 have a wider diffused sound so I can enjoy the rear channel sound in more places in the room. Front speakers are Focal Aria 926 and Aria center channel. I was concerned they would sound noticeably different especially with a smaller 4.5" driver but they sound great. Plenty of low end for surround effects.

Pros: Diffused sound Easy to hang well built

Cons: magnetic grills would be nice

High Quality Surround Speakers

Mike from Calumet, MI on 1/8/2019

Crutchfield Customer Review (What's this?)

I have owned Definitive Technology speakers for decades, and my new SR-9080s are replacing a 23-year-old pair of DefTech BPX surround speakers, which were similar in design and appearance to the new ones, being bipolar. The old pair actually still sounded good, but one of the cabinets had a bit of water damage due to an ice dam on the roof above quite a few years ago. The new ones are slightly smaller, and lighter in weight, so they were easier to mount on the walls of my listening/viewing room. The bipolar design allows the surround channels to properly diffuse throughout the room without losing any directionality when the movie soundtrack or music calls for it., They also have what seems to be a longer throw, to project sound out into my large (22' x 26') room. According to my Audyssey calibration, they need a bit less volume than the old pair did. They look great, sound great, and if they last as long as my previous pair, they should be the last surround speakers I need. Highly recommended.

Pros: Great looks, lightweight for wall mounting, and they project sound out into a large room very well.

Cons: None--except that I wish I had a mounting area for a 2nd pair of these.

Amazing speakers

Awesome sound wrong application for me

Dan from Spring Branch, TX on 2/5/2018

Crutchfield Customer Review (What's this?)

Since I am a Def-Tech fan I always look at their speakers first. Bought the speakers to round out my surround sound upgrade (ProMonitor 55'd L&R, Mythos 10 CTR, and the SR9080 for my rear surround). They sound great but they are the wrong fit for my application. I was going to put them on the side walls and try to flood the back of the room with sound from these speakers but since have had to move them to the back wall to face the rear of the listeners and to lower them to the right height. Looks like I will be return them and trying the Mythos Gem XL which are not bi-directional. Wish I could keep them.

Pros: Sound, price

Cons: Mounting options

Perfect upgrade from ProCinema 600 set. Fuller, richer sound, and non-obtrusive setup in small family room, which is how I like it. Probably have not fully used it's capability.

Great speakers

Crutchfield Customer Review (What's this?)

These are really great speakers. Hearing a lot of new sounds that I did not hear with my pro cinema 1000 speakers, which are very good speakers. I have these set up as my surrounds in my 7.2.4 speaker setup. Grab a pair of these while they are on sale, you won't regret it.

Pros: Wide range of sound. Easy to mount.

Surround Speaker: The Definitive Technology SR9080's bipolar speaker dispersion pattern provides enveloping surround sound, tremendous dynamic range as well as true high-definition sound quality, which results in total soundfield immersion. This compact, high-quality bipolar speaker is intended primarily for use as a surround or surround back speaker. In addition, it can also be used as front "effects" speakers in multichannel DSP systems.

Bipolar Design: The Definitive Technology SR9080 is a bipolar surround speaker, containing two full-range woofer and tweeter arrays. The speaker cabinet has three sides, with the driver arrays firing in phase approximately 100° apart to flood the area with sound and the third side mounts against the wall. Dispersing the surround channel's sound evenly over a broad area of the room creates an enveloping home theater experience.

Aluminum Dome Tweeters: The SR9080 bipolar surround speaker features two 1" aluminum dome tweeters for crystal clear highs that bring the most demanding audio soundtracks to life. Definitive Technology tweeters are 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 SR9080 employs two 4.5" midrange cone woofers 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.

Resonance-Free Cabinet w/ Acoustically Transparent Grilles: The Definitive Technology SR9080 uses a resonance-free cabinet w/ acoustically transparent grilles 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. Thanks to the speaker's acoustically transparent grilles, you'll enjoy the subtle elegance of the speaker design without having to remove a speaker grille to enjoy natural, uncolored sound.

Bass Port: On one side of the cabinet is a bass port for higher efficiency and deeper bass response.

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.

Mounting Options: The SR9080 has a rear-panel keyhole slot for wall-mounting. It can also be simply placed on a shelf or stand.

Placement: For use surround speakers, position the speakers approximately 6' high and directly beside or 1-2" behind the listening area. For use as surround back speakers, position the speakers approximately 6' high and 6' apart directly behind the listening area.

BP9000 Series: The SR9080 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.
