Crutchfield at CES: Definitive Technology BP9000 series speakers
From Definitive Technology: BP 9000 Series
The SR-9040's right- and left-facing driver arrays provide a more immersive surround sound experience.
Definitive Technology's SR-9040 surround speakers will instantly immerse you in every high-speed car chase, high-impact explosion, and bruising brawl that Hollywood blockbuster movies can deliver. Using left- and right-firing driver arrays that radiate full-range sound in an omni-directional pattern, the SR-9040s provide an enveloping listening experience that goes beyond ordinary surround speakers.
Each driver array in the SR-9040 has a 3-1/2" midrange paired with a 1" dome tweeter, for perfectly blended highs and mids. This bipolar design creates a big, immersive soundfield. Each 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.
Definitive's bipolar surrounds aren't fussy about placement — they shine in a variety of room sizes and shapes. A pair of SR-9040s 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).
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 product excellent sound output
These speakers are smaller than I expected, but delivers excellent sound quality. I was surprised to hear the quality of sound that came from these speakers. Excellent companion to the BP-9040. Highly recommend.
Pros: Looks great, sound awesome
These small bipolar speakers are just for surround -- ambient effects for the most part -- yet they sound great, and look fantastic. That's a bonus because visitors are likely to see them before they see the rest of my home theater setup. Construction is solid and installation with the keyhole mounts on the back panel is very easy. My only quibble is that running speaker wires behind them pushes the bottom of the speaker away from the wall slightly. Setup is easy, except that you want to be sure to set the right crossover frequency and set levels manually instead of using the automatic feature. Both are spelled out clearly in the setup guide.
Pros: Compact design, bipolar pattern, beautiful finish, easy installation
Love these speakers! Work great alongside with the rest of our highend sound system!
Pros: These speakers look great and sound great in our home entertainment system
Cons: We haven't found any cons. We've had them for a month now.
I bought these to complement my BP-9020, CS-9040 speakers and they are good. Initially I had the ProCinema 1000 speakers as Surround but had them replaced with the SR-9040 and I can definitely feel the difference. As one of the Crutchfield advisors advised, the SR-9040 are good for my speaker positioning (on the side). I am happy with the performance and would defnitely recommend them.
These speakers sound great with my other Definitive speakers. Matching sound all around was exactly what I was looking for .. The sound quality is impressive. I'm very happy with the way they blend into my speaker system. I got these on sale. that also helped lol
Pros: Great surround, details and highs. even pretty good rumble for little 3 1/2''
I purchased these surround speakers to complete my home theater setup (2 BP-9060 front, 1 CS-9060 center, 2 SR-9040 surrounds). They blend well with the other speakers in the setup and give a nice surround sound with their bi-polar design. They are a little tougher to get calibrated, but once set up, they do exactly what they are supposed to in enhancing the movie watching experience. Thanks to Crutchfield for their unparalleled service and selection!
These surrounds perfectly complemented the DefTech bipolar floor standers and center I have, essentially they completed the series for me. They sound excellent, greatly expanding my sound stage with their bipolar sound. They were very easy to mount and look great when the speaker wire is run correctly. I am very happy with my set up now, and will be suggesting DefTech to anyone who asks. Crutchfeild support was also excellent as always, I had a question and called support, I received the speaker placement documentation from the representative within 5 minutes of calling in and had an answer to my question. Great product, great buying experience, and the shipping was relatively quick too. Overall very happy with my purchase

Surround Speaker: The Definitive Technology SR9040'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 SR9040 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 SR9040 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 SR9040 employs two 3.5" 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 SR9040 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.
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 SR9040 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 SR9040 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.

Wanted to get matching surrounds for Definitive Technology Fronts and Center speakers recently purchased. [ Jon Jan 01, 2018 ]

Hi, I didn't look for a bracket, mounted the speaker on a appropriate size screw, pulled the wires out of a hole I made in the wall to coincide with the speaker terminals and it looks perfect. I figured when I'm no longer using the speakers I'll only have four little holes to spackle. [ Albert May 02, 2017 ]
Try these it says they are compatable with the single keyhole slot https://www.crutchfield.com/p_121AM30B/Pinpoint-AM30-Black.html [ Paul May 02, 2017 ]
