Customers are saying

Customers consistently note the excellent sound quality of the SR-9040 10” Bipolar Surround Speaker. They also find the speakers easy to install and appreciate the sleek design. However, some customers express a desire for more mounting options beyond the keyhole design. A few also mention the size as a potential drawback, preferring either smaller or larger versions depending on their needs.

    I use 6 of these speakers for surround and height speakers, and the sound quality is excellent. They are paired with DT 9020 towers and 9040 center channel and Denon 6400 amp. The surround speakers are crisp and clean and are better than I expected! Highly recommend!

    These Definitive Technology rear surround speakers compliment my DefTech towers and center speaker perfectly! The sound is great and not overpowering in my somewhat small room. I couldn't be happier, as now I can use my DefTech 1000's for the side speakers in my 7.2 system.

    To complement my Def Tech bipolar speakers, I decided to make my 5.1 system all Def Tech. These are matched perfectly with the tower speakers. I also set them up using the Rocket Fish wireless surround kit. Very pleased!!

    Fills the Room

    I have four of these for the surrounds and rear surrounds in a 7.2.4 Atmos setup. I have been very happy will how well they fill my larger room with sound. Sound has excellent placement within the room while at the same time not resulting in pinpointing exact speaker locations. Sound is naturally placed and pans through areas to the point it feels like there are many more speakers placed through the surround and rear surround area. I would prefer to have a little bit bigger version but not a big as the SR-9080s. Something in-between would have been the sweet spot for me.

    Very nice and great sound quality speakers. Matched these with my other home theater speakers to complete my system. Only bad thing I can say is that they weigh a lot more than I expected.

    Def Tech speaker was purchased to complete a 7.2.2 Dolby Atmos system. Paired with a Marantz SR 6011. Very crisp and clear sound. I obviously liked them enough to keep spending my money on them. The speakers are a little bulky and spendy, but in this case, they make up for this with exceptional sound!

    Excellent surround speakers, excellent pick for back speakers on 7.x setup. Can be excellent too on a 5.x setup, but make sure are they are bi-polar speakers.
