The Klipsch Reference R-40SA Dolby Atmos surround speakers deliver immersive sound, adding an extra layer to your home theater system. These speakers create a robust sound stage by featuring 4” TCP woofers, a large 90° X 90° Tractrix Horn, and a 1” LTS Tweeter.


Seek New Heights
Immersive sound comes alive from all directions, including overhead, with these Dolby Atmos® enabled speakers. Add them to any monitor or tower speaker, or use them as surround speakers for a hemisphere of rich, detailed sound.


Large 90° X 90° Tractrix Horn
An innovative horn design, including increased outer horn dimensions, will deliver more power and emotion to music and movies. Bigger means better, with directivity control over a larger bandwidth of frequencies, resulting in a more accurate sound stage.


Linear Travel Suspension (LTS) Aluminum Tweeter
A hallmark of Klipsch speakers, the exclusive 1” LTS with Kapton Suspension tweeter minimizes distortion for more detailed performances. Aluminum is an extremely light and rigid material used in the tweeter assembly to provide high efficiency.


Spun-Copper Thermoformed Crystalline Polymer Woofers
Utilizing trickle-down technology from Klipsch’s highly-acclaimed Reference Premiere series speakers, the 4” TCP woofers have steeper angling of the cones for a smoother response and improved accuracy and transparency.


Rear Tractrix Port
The rear Tractrix port is perfectly matched to the cabinet and woofers, creating ideal airflow with minimal distortion or turbulence even at the lowest frequencies.


High-Quality Cabinet Design & Appearance
Hidden fasteners, edge-to-edge horn, and low-profile magnetic grilles give the speakers a polished, modern appearance. MDF cabinets feature scratch-resistant, textured wood grain to fit right into home decor.


Premium Wire Management
Featuring innovative wire management and built-in topper connectors for discreetly adding Dolby Atmos, you won’t see cables sticking out from the back of the speaker. All you’ll hear is immersive, 360° sound.
