Klipsch R-40SA Dolby Atmos Surround Speakers (Pair) at Vinyl Sound Toronto Canada

The R-40SA is a Dolby Atmos elevation and surround loudspeaker from Klipsch (Indianapolis, Indiana, USA), available at Vinyl Sound in Toronto, Canada. Part of the Reference series, the R-40SA is engineered to add a full overhead dimension to home theater systems, conforming to official Dolby Atmos specifications for height channel reproduction. Each speaker combines a 1-inch LTS Aluminum Tweeter with Kapton Suspension on an all-new 90° x 90° Tractrix Horn with a 4-inch Spun-Copper Thermoformed Crystalline Polymer (TCP) woofer, handling up to 50 watts RMS continuous and 100 watts peak at 8 ohms. The R-40SA can be placed atop any compatible floor-standing or bookshelf speaker to add Atmos height channels, or deployed as a standalone surround speaker, making it one of the most placement-flexible Dolby Atmos elevation solutions in the Reference series lineup.

All-New 90° x 90° Tractrix Horn Technology

The redesigned 90° x 90° Tractrix Horn at the heart of the R-40SA represents a significant step forward over previous Reference series horn geometry. Increased outer horn dimensions extend directivity control over a wider bandwidth of frequencies, meaning the horn maintains precise coverage patterns further into the midrange rather than narrowing as frequency rises. The practical result is improved high-frequency directivity and a more stable, accurate soundstage as Atmos overhead effects transition across channels. An edge-to-edge horn design extends the acoustic aperture to the full width of the cabinet baffle, maximizing the usable radiating area and contributing to the speaker's clean, uncluttered front appearance. Hidden fasteners and a low-profile magnetic grille complete the polished aesthetic, allowing the R-40SA to sit on top of a tower speaker or on a shelf without drawing visual attention away from the primary speakers.

LTS Aluminum Tweeter with Kapton Suspension

The 1-inch aluminum tweeter uses Klipsch's Linear Travel Suspension (LTS) with a Kapton suspension element to guide the diaphragm through strict piston motion across its full excursion range. Aluminum provides an exceptional combination of rigidity and low mass for the tweeter diaphragm, exceeding the high-frequency extension and transient response achievable with polymer or silk alternatives while remaining lighter than titanium formulations used in higher Reference Premiere tier speakers. The Kapton suspension material contributes dimensional stability under thermal and mechanical stress, maintaining consistent performance over long listening sessions at higher output levels. LTS minimizes harmonic distortion at the voice coil, allowing the fine spatial detail encoded in Dolby Atmos overhead sound objects to be rendered with clarity rather than smeared by intermodulation artifacts.

Spun-Copper Thermoformed Crystalline Polymer (TCP) Woofers

The 4-inch TCP woofer in the R-40SA brings trickle-down materials technology from Klipsch's Reference Premiere series into the Reference line. Thermoformed Crystalline Polymer cones are formed at high temperature into a shape with steeper cone angles than conventional woofer designs, which produces a smoother frequency response curve and improved midrange accuracy and transparency. The spun-copper finish identifies the precise layering and alloy specification of the cone material, and ribbing added to the cone surface increases stiffness to reduce cone breakup at higher output levels. The overall result is a 4-inch driver that handles the limited but critical frequency range of a Dolby Atmos height channel with greater linearity and less coloration than a standard injection-molded cone woofer of comparable diameter.

Premium Cabinet Construction and Wire Management

The R-40SA cabinet is constructed from reinforced 3/4-inch MDF with an all-new internal bracing design that reduces panel resonance and cabinet vibration for improved sonic accuracy. A scratch-resistant, textured black wood grain vinyl exterior ensures the speaker integrates cleanly into any room decor without requiring special placement accommodations. Innovative rear-panel wire management routes speaker cable discretely away from the connection point, preventing cables from being visible when the R-40SA is positioned on top of a floor-standing speaker. A single gold-plated binding post provides a secure, corrosion-resistant connection, and Klipsch includes jumper wires in the box for fast integration with compatible Reference series floor-standing speakers including the R-600F and R-800F.

Frequently Asked Questions

What is the Klipsch R-40SA?

The Klipsch R-40SA is a Dolby Atmos elevation and surround loudspeaker sold as a pair, from the Reference series by Klipsch, Indianapolis, Indiana, USA. Each speaker houses a 1-inch LTS Aluminum Tweeter with Kapton Suspension on a 90° x 90° Tractrix Horn and a 4-inch Spun-Copper TCP woofer in a sealed MDF cabinet, handling 50 watts RMS continuous and 100 watts peak at 8 ohms. The R-40SA is designed to add overhead Dolby Atmos height channels to existing home theater systems by placing each speaker on top of a compatible floor-standing or bookshelf speaker, or to function as a conventional surround speaker in a 5.1 or 7.1-channel layout.

How does the Klipsch R-40SA compare to the Klipsch R-41SA?

The Klipsch R-40SA is the direct successor to the R-41SA and replaces it across the Reference series lineup. The R-40SA features an all-new Tractrix Horn with increased outer dimensions for directivity control over a wider frequency bandwidth, a redesigned 4-inch TCP woofer with steeper cone angles borrowed from the Reference Premiere series, and an updated internal bracing structure that reduces cabinet vibration more effectively than the R-41SA enclosure. Against third-party alternatives, the R-40SA competes directly with the Polk Audio MagniFi Atmos module, Definitive Technology A90 elevation speaker, and Yamaha NS-AW294 outdoor-rated Atmos speaker, but differentiates through its Tractrix Horn loading and LTS tweeter technology, which are absent in most competing elevation speaker designs at this tier.

Can the Klipsch R-40SA be used as a surround speaker instead of an Atmos elevation speaker?

Yes, the Klipsch R-40SA functions as a conventional surround speaker for 5.1 and 7.1-channel home theater systems when not used in the Dolby Atmos elevation configuration. Its sealed enclosure, 90° x 90° Tractrix Horn dispersion, and compact 7 x 5.75 x 12.7-inch footprint make it practical for wall-shelf or stand placement at side and rear surround positions. The 8-ohm impedance and standard binding post input are fully compatible with any AV receiver surround channel output, and the speaker's frequency response conforms to the broader Dolby Atmos specification which covers both height and surround channel applications.

What is Thermoformed Crystalline Polymer (TCP) and why does it matter?

Thermoformed Crystalline Polymer (TCP) is the cone material Klipsch uses for the R-40SA woofer, derived from technology developed for the Reference Premiere series. TCP cones are formed at high temperature into their final shape with steeper sidewall angles than conventional injection-molded cones, which distributes the radiating surface more efficiently and produces a smoother frequency response curve across the driver's operating range. The crystalline polymer structure is inherently rigid, which reduces cone breakup at higher frequencies and minimizes the harmonic distortion that breakup introduces. Surface ribbing added to the TCP cone further increases stiffness without adding mass, preserving the driver's efficiency and transient speed.

Where can I buy the Klipsch R-40SA in Toronto or Canada?

The Klipsch R-40SA Dolby Atmos Surround Speakers are available at Vinyl Sound, an authorized Klipsch dealer in Toronto, Canada. Vinyl Sound serves customers across the Greater Toronto Area and ships across Canada, providing full Klipsch manufacturer warranty support and expert guidance on integrating the R-40SA into an existing Reference or Reference Premiere home theater system. Purchasing from an authorized Canadian Klipsch dealer ensures genuine product and full warranty validation.

Which Klipsch floor-standing speakers is the R-40SA compatible with?

The Klipsch R-40SA is designed as a plug-and-play Atmos elevation add-on for the Klipsch R-600F and R-800F Reference series floor-standing speakers, and jumper wires for those models are included in the box. The R-40SA's flat-bottom sealed enclosure and compact footprint also allow it to be placed on top of any sufficiently wide monitor speaker or bookshelf speaker with a stable top surface. For systems built around the Reference Premiere series, the Klipsch RP-500SA and RP-502S Atmos-capable speakers are the tonally matched elevation options within that product family, while the R-40SA is the natural companion to Reference series R-600F and R-800F tower systems.

Does the Klipsch R-40SA require a Dolby Atmos AV receiver?

Yes, realizing the full Dolby Atmos overhead channel capability of the R-40SA requires an AV receiver with Dolby Atmos decoding and dedicated height channel amplifier outputs. Current Dolby Atmos-capable receivers from Denon, Marantz, Yamaha, Sony, and Onkyo at mid-range and above provide the necessary processing and amplification. The R-40SA can also be used as a conventional surround speaker with any standard stereo or multichannel receiver that does not support Atmos, in which case it simply functions as a 5.1 or 7.1 surround speaker rather than a height channel driver.

How is the Klipsch R-40SA connected to a floor-standing speaker for Dolby Atmos use?

The Klipsch R-40SA connects to a dedicated height channel output on a Dolby Atmos AV receiver using the speaker's single gold-plated binding post and standard speaker wire. It is not electrically connected to the floor-standing speaker it sits on top of. The R-40SA is a passive speaker that requires its own amplifier channel, separate from the floor-standing speaker's channel. Klipsch includes pre-fitted jumper wires in the box specifically for routing speaker cable between the R-40SA and the top panel connection points on the R-600F and R-800F, simplifying cable management when the speakers are used in that configuration.
