Features

Dolby Atmos Height Speaker Module: The Dolby Atmos Reserve Series R900 height speaker module is designed to sit atop of Polk's Reserve Series bookshelf (R200) and floorstanding loudspeakers (R700/R600/R500) - all sold separately. The R900 is timbre-matched for premium performance with Polk's Reserve Series loudspeakers, but can also be used with other Polk series and other brands of loudspeakers as a "topper" speaker or "on-wall" speaker. Flip the switch on the back of the speaker to select the desired position and the speaker will automatically adapt to the optimal performance.

  • Topper Application: As a "Topper", the R900 height speaker module simply sits on top of a compatible loudspeaker. The rear-panel switch should be set to "On Speaker". The R900 measures 6.5625" (w) x 6.25" (h) x 12.625" (d), when used as a topper.
  • On-Wall Application: The R900 can be mounted to a wall using its integrated keyhole slots and wall-mount screws (not included), or its 1/4"-20 threaded insert with an optional articulating mounting bracket (sold separately). The rear-panel switch should be set to "On Wall". The R900 measures 6.5625" (w) x 12.625" (h) x 6.25" (d) , when used on-wall. *Not designed to mount on a ceiling.

Note: The R900 height speaker module weighs 6.6 lbs.

Dolby Atmos & DTS:X Compatible: The Polk Reserve Series R900 height speaker module is Dolby Atmos certified and designed to meet DTS:X specification. The R900 is designed to deliver the 3D audio found in today's Dolby Atmos, DTS:X, and IMAX enhanced movie and music soundtracks. Once installed, the R900 height speaker module fires sound upwards, which is then reflected off the ceiling and back down to your listening area. As a result, you'll enjoy clear detailed three-dimensional sound without having to install additional speakers in your ceiling.

Note: While the Polk R900 is certified for Dolby Atmos and DTS:X content, nearly any content can be improved with the addition of the R900 height speaker module. For example, nearly all Dolby Atmos AV receivers feature a Dolby surround up-mixer function that automatically adapts any traditional channel-based signal to the new, full capabilities of your system, including the R900 height module. This ensures that you hear realistic and immersive 3D sound, no matter what you're playing.

Vertical 2-Way Driver Array: A vertical 2-way driver array allows flexible placement either on a wall or placed directly on top of a compatible Polk Reserve Series loudspeaker. A vertical dispersion pattern directs sound perfectly to the correct area of the ceiling into the optimal listening area. You will enjoy exceptionally realistic overhead sound in a comfortable and convenient listening area without the hassle of installing speakers in your ceiling.

  • 0.75" Pinnacle Ring Radiator Tweeter: The 1" high definition Pinnacle ring radiator tweeter, developed by Polk Audio, delivers ultra-clear, crisp highs without unwanted coloration or distortions. The Pinnacle tweeter features a finely tuned waveguide that dramatically improves the dispersion of high frequency energy ensuring a broad "sweet spot" and while the critically damped rear-chamber helps to defeat any unwanted resonances. Hi-Res certified, the Pinnacle Tweeter is designed for today's multichannel 3D audio found in music, movies, sports, and video games soundtracks.
  • 4" Turbine Cone Woofer: The height speaker module houses a single 4" Turbine Cone woofer to handle midrange, midbass, and bass frequencies. Polk developed the new Turbine cone to ensure the natural reproduction of the midrange, the frequencies our ears are so sensitive to. The Turbine cone combines Polk's proprietary foam core and the molded Turbine geometry which dramatically increases stiffness and damping, without adding mass - resulting in a smooth, detailed midrange and effortless bass.

Hi-Res Certified: With Hi-Res Audio certification, the Polk Reserve R900 delivers clear and detailed high-end response. Female vocals are particularly smooth, with exceptional clarity and without coloration. Plus, a minimum support of 40kHz perfectly reproduces the latest Hi-Res Audio files with improved audio extension.

Acoustic Suspension Cabinet: The R900 features a fully sealed enclosure to prevent resonances and distortions. Polk believes a speaker cabinet should be beautiful and add nothing to the playback. The Reserve Series speaker cabinet is carefully cross-braced to eliminate unwanted interior resonances, while rounded exterior corners help disperse sound broadly around the room with minimal diffraction, creating an open sound stage. A cloth grille attaches magnetically to the front of the speaker enclosure.

Binging Post Terminals: The Polk Reserve Series R900 height speaker module is equipped with a set of nickel-plated, binding-post terminals that will accept bare wire (16-10AWG), pin-connectors, spade-lugs, and banana-plugs (single only).

Reserve Series: The Polk Reserve Series offers modern styling combined with Polk's premium Pinnacle tweeter and Turbine midrange/midbass driver that deliver high-resolution detail and imaging. Plus, Polk's new X-Port and Power Port 2.0 technology help to deliver deep and effortless bass for a more immersive experience. The Polk Reserve Series consists of three floorstanding loudspeakers (R700/R600/R500), two bookshelf loudspeakers (R200/R100), two center-channel speakers (R400/R300), a LCR loudspeaker (R350), and a Dolby Atmos height speaker module (R900) - all sold separately.

Optional Power Subwoofer: Add one of Polk's powered subwoofers (sold separately - see Accessories Tab) for bigger, deeper, and more impactful bass when listening to your favorite movie and music soundtracks.

Q
I would like to pair them with my RTi10 for Atmos experience and also install 2 of them for rear surond.?Any input apriciated
[ Sparky182  Jul 26, 2022 ]

Greetings, and thank you for your question. The Polk Audio R900 would perform nicely as Dolby Atmos toppers with your RTi10s. They can also be used as rear surrounds although not considered surround speakers. They play what they get. Depending on how you need to mount the rear surrounds, they might be a perfect option if they need to go higher up the wall, more towards the ceiling.

Q
My room is about 20 by 25. Will these speakers if placed on the front wall, provide over head sound with just 5.1.2 setup?
[ Gary  Feb 24, 2022 ]
3 answers
A
I have only tried these as rear surrounds but I am sure they would work in a 5.1.2 setup. The best option would be an in-ceiling speaker for the height application but if you can't pull that off, the setup you are suggesting will work. By the way, I have these speakers in a 24 x 25 room and they fill the space nicely.
[ ROBERT  Feb 25, 2022 ]
A
I have a 5.1.2 and believe the best option for using these as Atmos would be to have them firing up, sitting on top of your front speakers (if you are looking for the over head sound).
[ Shane  Feb 24, 2022 ]
A
It does for my room but mine is roughly 15x15.
[ BYRON DAVID  Feb 24, 2022 ]
Q
When placed on top of the front speakers, should the receiver be programed for where the speakers are or where the sound is going to bounce off the ceiling, programing as if they were ceiling speakers. Does the placement switch compensate for this? Has anyone tried both?
[ John  Nov 16, 2021 ]
2 answers
A
The receiver should be programmed for where the speakers are. The switch is for either placing them on sop of the main speakers or on the wall. For me, on the wall sounded better!
[ Joseph  Nov 16, 2021 ]
A
I am by no means an expert but I have a Marantz SR 7015 that I am using as a pre amp connected to a Marantz MM 8807 amplifier with a Polk Reserve series surround speaker set up and I have mine set to where the speakers are and it sounds amazing.
[ BYRON DAVID  Nov 16, 2021 ]
Q
I purchased some stout 1/4-20 mounts for these speakers, but the threaded hole in the speaker is larger. Is there supposed to be an insert that changes from the larger thread size down to 1/4-20 (e.g., same as camera tripods)? Alternatively, what is the "optional articulating mounting bracket (sold separately)"?
[ David  Nov 14, 2021 ]
2 answers
A
I had the same issue. The thread on the back of the r900 is 3/8", not 1/4"-20. You can purchase adapters (male 3/8 to female 1/4-20) from a place in CA-just search it. Please be advised that the GoldenEar mounts listed under the "Accessories" tab of this product do not fit without that adapter!
[ Michael  Mar 25, 2022 ]
A
We do not know of an insert that will reduce the size of the threaded hole. We offer a few different mounting brackets that can work with these speakers. Those mounts can be found in the Accessories section of this web page
[ Paul  Nov 16, 2021 ]  Staff
Q
If placed on the wall, must these speakers be placed directly above the left and right front speakers?
[ Gary  Sep 01, 2021 ]
1 answer
A
No, they do not have to be directly above the left and right speakers. Mine are offset about 3ft to the left and right and approx. 3ft behind my main channel left and right speakers and they sound great!! Mike
[ Michael  Sep 01, 2021 ]
Q
Why "only" the R series speakers? Is the R900 'that' intuitive, that it will not work with any other Polk series (tower) loudspeaker?
[ mxinrik  Jul 29, 2021 ]
2 answers
A
I read on the Polk Audio site that the R900's work better with the R series speakers because they have a better tonal sound match too.
[ Michael  Sep 01, 2021 ]
A
The cosmetic match as shown in the picture which has them placed on top of compatible Polk speakers is only expected to occur with those matching Polk speakers. However, any speaker with a flat top that is big enough to hold these R900's could work as a installation place for them.
[ Paul  Aug 01, 2021 ]  Staff
Q
How would these work (tone match) with polk RTI A7 towers? I'm looking for a solution for atmos height speakers without ceiling mounting.
[ Patrick  Jun 16, 2021 ]
1 answer
A
The R900 is timbre-matched for premium performance with Polk's Reserve Series loudspeakers, but can also be used with other Polk series and other brands of loudspeakers as a "topper" speaker. While they aren't perfectly timbre matched, they should work very well still!
[ Calvin  Jun 18, 2021 ]  Staff
Q
Can the r900 be used as a rear surround?
[ Joe  Jun 02, 2021 ]
2 answers
A
Sure.
[ Joseph  Nov 16, 2021 ]
A
We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.
