About the Klipsch Reference R-40SA

Archer A.

Add another dimension to your home cinema

There are few things more immersive (and awesome) than watching a film and losing yourself in its soundtrack. Thanks to surround sound formats like Dolby Atmos, you can be right in the middle of the action. But that level of immersion takes some extra equipment to get the full effect.

Add another dimension to your home cinema

There are few things more immersive (and awesome) than watching a film and losing yourself in its soundtrack. Thanks to surround sound formats like Dolby Atmos, you can be right in the middle of the action. But that level of immersion takes some extra equipment to get the full effect.

Klipsch's new Reference R-40SA speakers were made to deliver crisp overhead sound effects and add an extra dimension of sound to your favorite films. These speakers use Klipsch's new cone material and sport an updated tweeter for better sound. 

Third-generation drivers

The R-40SA's 4" woofer uses spun-copper TCP (thermoformed crystalline polymer) for its cone material. Klipsch chose this material because of its smooth response and transparency. The woofer also uses some trickle-down technology from the company's more expensive Reference Premiere line. It has a similar cone shape and uses additional ribbing for extra rigidity, which reduces distortion at higher frequencies. 

The hallmark 90°x 90° Tractrix® horn features an upgrade too. Klipsch widened its opening for more high-frequency directivity. That means the 1" LTS (Linear Travel Suspension) tweeter inside the horn disperses sound over a wider area.

How do they work?

These Atmos "toppers" sit on top of Klipsch's Reference tower speakers and bookshelf speakers. They work by firing sound upward and reflecting it off your ceiling and down onto your listening position. They're a great alternative to cutting holes in your ceiling for custom-install speakers.

The neat thing is that these can also work as regular surround speakers. You can wall mount them using the rear keyhole slots and have them facing your listening position for side-or-rear surround sound effects.

Do you have an Atmos-capable receiver?

These speakers require a home theater receiver with Dolby Atmos when placing them on top of your other speakers for overhead effects.

Product Research


Dolby Atmos Elevation Speaker: Enhance your home theater system with the overhead sound effects of the Klipsch R-40SA Dolby Atmos speaker. By leveraging Klipsch proprietary horn-loaded controlled directivity technology, the R-40SA bounces sound off the ceiling to create an astonishing, immersive listening experience.

Note: Dolby Atmos delivers captivating, object-based sound that places and moves audio anywhere in the room to bring entertainment alive all around the audience. With Dolby Atmos sound comes alive from all directions, including overhead, to fill a home theater with astonishing clarity, power, detail and depth.

Application & Mounting Options: In addition to delivering overhead sound effects as a Dolby Atmos speaker topper for Klipsch and other brands of floorstanding and bookshelf loudspeakers; the R-40SA is designed to be wall-mounted as a front, rear or side elevation speaker; or as a versatile side or rear surround sound speaker. There is a threaded keyhole slot on the back, as well as four integrated rubber feet on the bottom of the speaker.

  • Dolby Atmos "Topper Application: The R-40SA fits perfectly on top of the Klipsch R-800F and R-600F floorstanding loudspeakers. Keep in mind the R-40SA's dimensions when using it as a Dolby Atmos topper for other models and brands of speakers, as it must be able to rest on top of your floorstanding or bookshelf loudspeaker. The R-40SA measures 5.8125" (w) x 7.0" (h) x 11.0625" (d).
  • Wall-Mount Application: The R-40SA mounts easily on the wall using its integrated keyhole slot (mounting screws not included). When wall mounted, the R-40SA measures 5.8125" (w) x 11.0625" (h) x 7.0" (d).

1" Horn-Loaded Tweeter: The R-40SA Dolby Atmos loudspeaker features Klipsch's proprietary Tractrix Horn technology mated with a 1" LTS aluminum tweeter, for impressive high-frequency response and greater extension, enhanced imaging and powerful dynamics.

  • 90°x90° Tractrix Horn: The square Tractrix Horn delivers a 90° (w) x 90° (h) dispersion pattern and features an increased outer horn dimension that allows for directivity control over a larger bandwidth of frequencies, resulting in improved high frequency directivity and a more accurate soundstage. Klipsch exclusive Tractrix horn technology ensures that the speaker's high frequency energy is aimed at the listener and reduces artificial reverb or filtering caused by indirect sound bouncing off of walls. Using this proprietary focused technology provides clarity, dynamics, and detail for your movies and music.
  • LTS Aluminum Tweeter: Behind each horn lies a 1" LTS aluminum tweeter with a Kapton suspension. Klipsch exclusive Linear Travel Suspension (LTS) minimizes distortion for enhanced, detailed performances. Aluminum is an extremely light and rigid material used in the tweeter assembly to provide high efficiency and improve resolution and detail.

4" Spun-Copper TCP Woofer: The Klipsch R-40SA houses one 4" Spun-Copper TCP (Thermoformed Crystalline Polymer) woofer for deep, smooth, and accurate bass. TCP woofers have steeper angling of the cones for a smoother response and improved accuracy and transparency. The additional ribbing increases the overall rigidity for less cone breakup at higher frequencies.

MDF Cabinet: The Klipsch R-40SA Dolby Atmos speaker features a MDF cabinet with a scratch-resistant, textured wood grain vinyl that seamlessly integrates into almost any room or decor. The enclosure's reinforced MDF construction reduces cabinet vibration for less audible coloration and improved sonic accuracy. The MDF enclosure also features a satin painted baffle with a scratch resistant design for an elegant look without the grille.

Acoustically Transparent Grille: The Klipsch R-40SA Dolby Atmos loudspeaker comes with a removable, black cloth grille that is magnetic and acoustically transparent. This strong magnetic grille provides protection and a sleek aesthetic look to compliment your home's decor.

Binding Posts: The Klipsch Reference III series Dolby Atmos speaker is outfitted with sturdy binding posts to ensure a secure connection to many types of cable and connectors. The binding post terminals will accept banana plugs (single only), pin-connectors, spade-lugs and bare wire (up to 12AWG).

Reference III Series: Klipsch's new Reference III series features updated Tractrix Horn technology, a new Spun-Copper TCP (Thermoformed Crystal Polymer) woofer design, and Tractrix geometry port technology to create a wide soundstage that is smooth, controlled and accurate. The Reference III series by Klipsch consists of a variety of floorstanding (R-800F / R-600F / R-605FA), bookshelf (R-50M / R-40M), center (R-50C / R-30C), and Atmos speakers (R-40SA) - all sold separately.

Optional Powered Sub: For bigger & deeper bass response, pair the Klipsch Reference III series loudspeaker with one of Klipsch's powered subwoofers (sold separately - click on Accessories Tab).

Customer Q&A

2 questions already asked

Does R40SA work/can be connected w/ tower speakers rf82 -ll?
[ Mohan  Nov 22, 2022 ]
1 answer
These R40SA will not connect to your sweet RF-82 II's directly Moh, but they can sit on top and be used for Atmos! These speakers do need their own power to drive them and to be wired with speaker wire just like your Klipsch towers. You will need to also have an Atmos capable 7-channel home theater receiver in place to use these as Atmos height speakers with your Klipsch Rf-82 II's. If you have two extra channels on your receiver or amp/processor, these sit right on top of your L and R mains and sound great!
[ Bo  Nov 22, 2022 ]  Staff
Can the R-40SA be used as rear wall mounted Atmos (height) speakers when angled down towards the listener for the overhead Atmos sound?
[ ROBERT  Sep 23, 2022 ]
1 answer
This would be possible. These speakers are equipped with keyhole mounting slots that would allow them to be easily mounted to a wall. If placed up high, they can work as Atmos height speakers. However, if they are too far away from your seating location, it may sound more like the sound is coming from behind instead of above. Our advisors are happy to review the project with you.
