Our take on the Definitive Technology SR-8080BP

Definitive's SR-8080BP bipolar surround speaker demonstrates how intensely realistic surround sound can be. It contains left- and right-firing driver arrays that radiate full-range sound in an omni-directional pattern — you'll really hear the difference as on-screen action shifts seamlessly from one side of the room to the other. Part of Definitive's Bipolar Series, it uses advanced driver design and rock-solid build quality to give you exceptional detail and presence with ambient effects and multichannel music.

Bipolar technology immerses you in the surround experience

Definitive's SR-8080BP bipolar surround speaker demonstrates how intensely realistic surround sound can be. It contains left- and right-firing driver arrays that radiate full-range sound in an omni-directional pattern — you'll really hear the difference as on-screen action shifts seamlessly from one side of the room to the other. Part of Definitive's Bipolar Series, it uses advanced driver design and rock-solid build quality to give you exceptional detail and presence with ambient effects and multichannel music.

High-tech drivers for exceptionally detailed sound

Each driver array in the SR-8080BP has a 4-1/2" mid/woofer paired with a 1" dome tweeter, for perfectly blended highs and mids. This bipolar design creates a big, immersive soundfield, which is really effective for surround speakers. Each pure aluminum dome tweeter has a silk surround, allowing it to reveal delicate, low-level ambient sounds. And thanks to Definitive's Balanced Double Surround System (BDSS) drivers, 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 smooth, engaging 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-8080BPs works well on your side walls for 5.1 systems, or on the side and rear walls for a 7.1 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 sound.

Build a complete Definitive home theater system by adding perfectly matched bipole towers (see the BP-8020ST, BP-8040ST, BP-8060ST, and BP-8080ST) and a center channel (see the CS-8040HD, CS-8060HD, and CS-8080HD).

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. For more information and helpful tips, check out this article from Definitive's website about conditioning your speakers.

James from Maryland on 3/8/2016

Crutchfield Customer Review (What's this?)

These speakers sound great as the rear speakers in a 7.2 system. If I had the chance for a do-over I would purchase two pairs of these speakers instead of the one pair of these and one pair of the 8040's.

Pros: Worth it.



Gary from Mi on 2/10/2016

Crutchfield Customer Review (What's this?)

Pros: Sound great look great

Cons: None

Crutchfield Customer Review (What's this?)

Sweet SPEAKERS, to bad they are discontinuing this line. WOW-perfect sound, I purchased four SR-8080BP a little over kill for the space, but movies never have sounded so good... hanging them on the wall was a search for another product and with a total weight of 13lbs I needed a strong wall hanger. I found a company which sells wall hangers, and they are sweet...OMNI 15.0W speaker wall mount...has other products to consider..

Pros: great sound...

Cons: NON>>>

Well worth the price!

GK from Delaware on 1/12/2016

Crutchfield Customer Review (What's this?)

Got them on a Manufacturer promotion at Crutchfield ( thanks to Crutchfield's wonderful customer service). Accurate reproduction of the surround effects. Impressed by the low frequency coverage(going down to 40Hz), power handling(upto 200W), efficiency(92dB). Solid build(13lbs for surrounds!) and nice looks/polished finish. Pairs nicely with my Marantz and Focal front stage, as if they are native surrounds...and yes, bipolar is the way to go for surrounds(IMHO).

Pros: - Solid build - Frequency range - Power handling - Efficiency(92dB) - Crisp reproduction in movies

Cons: None so far

Used for surround back speakers in a 7.1 system. After calibration of speakers they sound fantastic. Just enough base.

Pros: Good build and quality.

Cons: None

Really nice surround sound

ACon from Massachusetts on 12/21/2015

Crutchfield Customer Review (What's this?)

replaced some former rear surround speakers with these Different and much more distinct sounds that I had not heard before when watching the same movie. I have some older Mythos 2 front speakers and a Mythos 3 center, and these 8080 seem to fill in nicely with them.



Great value on a quality set of speakers

Amazing surrounds

Anonymous from Lexington, KY on 12/19/2012

Crutchfield Customer Review (What's this?)

I have never had surrounds that sound this good. You can hear every detail and realize the things you have missed out on.

Pros: Amazing sound

Cons: Not really a con but extremely large. Have to mount or out on a stand.


Jimmy from Lafayette LA. on 9/25/2012

Crutchfield Customer Review (What's this?)

These speakers are great, I was not expecting the low frequency response that they produce. I was truly impressed with the sound.

Pros: Great sound, easy to install, look great.

Cons: Costs, but they sound great.


Hands-on research

Product Research


Bipolar Design: The Definitive Technology SR-8080BP 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 (the third side mounts against the wall). Dispersing the surround channel's sound evenly over a broad area of the room creates an enveloping movie experience.

Drivers: The two woofers used in the SR-8080BP are 4-1/2" second generation BDSS (Balanced Double Surround System) drivers. BDSS is Definitive's patented technology that supports the speaker cone at both the inner and outer edges allowing longer and more linear excursion for greater clarity and detail. The new Linear Response Waveguide (patent pending) smoothes off-axis frequency response and disperses sound over a wide area. The two tweeters are pure aluminum domes, heat-treated to relax the crystal structure, then coated with a ceramic to produce extended highs. The Linkwitz-Riley crossover networks maintain a smooth output around the crossover frequency.

Voice-Matched: The SR-8080BP is a full-range low-distortion speaker which is timbre-matched to blend perfectly with all of Definitive's BP series speakers.

Binding Posts: The speaker terminals are gold-plated, 5-way binding posts and will accommodate spade connectors, single or dual banana plugs, pin connectors, and bare wire up to 10 gauge.

Mounting: The SR-8080BP is designed for easy placement; it has a keyhole slot for wall mounting, or it can be placed on a shelf or stand. It's designed as a surround speaker (surround or surround back channels), but can also be used for front effects channels in Audyssey DSX, Dolby Pro Logic IIz, or Yamaha DSP 3D (with presence speakers) systems.

Why did you buy this?

i bought the definative sr-8040s and love them. im going to use those for my rears and the 8080s for my surrounds. everything else is definative and got to have the timbre match. i have 2 svs sb-2000s that im really happy with also. [ matt  Apr 09, 2016 ]
I always want a Definitive Technology Dipolar speaker, but it is expensive since there is sale it is time to get it [ The  Mar 30, 2016 ]
Rear effects sound quality in surround sound. [ Don  Mar 21, 2016 ]
Price was right. Specs show it should be a great speaker. Comments from customers here and other sites really like them. [ Jeff  Mar 15, 2016 ]
lots of research for quality led me to the Def Tech line of bipolar speakers... and they were also on sale [ David  Jan 22, 2016 ]
I already have a pair for rear speakers. This would be a great addition for game room as extended zone or zone 2. [ Geetha  Dec 20, 2015 ]
I initially selected the SR-8040, however after speaking with Chip and reviewing the price difference. The numbers made the SR-8080 the selection of choice. Thanks Chip! [ Howard  Dec 09, 2015 ]
To pair with procenter 2000 and promonitor 1000 [ EnlightMent  Dec 05, 2015 ]

1 question already asked

These are book shelf speakers and do not come with stands. These can be wall mounted, but heavy wall mount hooks are needed. I bought my hooks at lowes and have been using them for over a year now. [ ANAND  Aug 11, 2015 ]
Made speaker stands for these speakers. Too awkward shape to mount but worth every penny. [ PHILIP  Aug 09, 2015 ]
wall mounts [ Jon  Aug 09, 2015 ]
Mine are mounted to the wall. Not really wall mounts, just screws in the wall that the speakers attach to. [ BARRY  Aug 08, 2015 ]
These are not that heavy. I mounted them with drywall anchors and screws. They come with hooks on the back. [ MIKE  Aug 08, 2015 ]
I drilled screws into wood studs, then hung these using the keyhole on the upper back; I also used blutack on the back bottom corners to prevent vibration. These are great speakers for rear surround channels, I own 4 of them (2 separate systems). [ THOMAS  Aug 08, 2015 ]
Mine are mounted directly to the wall. Speakers have a keyhole in back for a screw. [ ADAM  Aug 08, 2015 ]
