Klipsch RP-140D On-Wall Speaker at Vinyl Sound Toronto Canada

The RP-140D is a two-way, bass-reflex on-wall speaker from Klipsch (Indianapolis, USA), available at Vinyl Sound in Toronto, Canada. The most compact model in the Reference Premiere Designer On-Wall series, it brings the identical acoustic technology as Klipsch's Reference Premiere box speakers to a cabinet measuring just 2.4 inches deep and weighing 3.75 lbs. A single 3.5" spun-copper Cerametallic woofer and a 1" Titanium Dome Linear Travel Suspension (LTS) tweeter on a 90x90 degree Tractrix Horn deliver a frequency response of 69Hz to 25kHz and a sensitivity of 91dB, with power handling up to 50W RMS. Sold individually, the RP-140D is designed for any position in a home theater or music system — front left, center, right, side surround, or rear surround — wherever floor space is at a premium and a clean, modern aesthetic is required. Available at Vinyl Sound in Toronto and shipping across Canada.

Reference Premiere Acoustic Technology in the Smallest On-Wall Cabinet

The RP-140D is built on the identical driver platform as larger Reference Premiere speakers including the RP-600M, RP-8000F, and RP-504C. The 1" LTS titanium dome tweeter is the same unit used across the entire Reference Premiere line, and it is loaded onto a 90x90 degree Tractrix Horn that controls dispersion precisely across the horizontal and vertical listening field. This shared driver lineage makes the RP-140D tonally identical to any Reference Premiere speaker it accompanies in a system, including the RP-240D on-wall speaker, the RP-440D SB passive soundbar, and the RP-500SA Dolby Atmos elevation module. A pair of RP-140D speakers can serve as left and right front-stage speakers flanking the television, or as rear surrounds in a 5.1 or 7.1 system, with zero timbral discontinuity between positions. The compact 6-inch-wide cabinet fits comfortably in spaces where even the RP-240D would be too tall, making it the natural choice for installations with tight vertical clearance or small room dimensions.

Linear Travel Suspension Tweeter and Cerametallic Woofer Technology

The LTS tweeter in the RP-140D uses a precision suspension mechanism that keeps the titanium diaphragm traveling in a geometrically straight path throughout its excursion range. Where conventional tweeter suspensions introduce arc-shaped motion that increases distortion at higher output levels, the LTS design maintains near-zero geometric distortion whether the speaker is playing whisper-quiet ambient sound or full dynamic film effects at reference level. The result is high-frequency detail that remains clear, natural, and fatigue-free across extended listening sessions. The 3.5" Cerametallic woofer uses a spun aluminum cone formed into a complex curved profile and finished with a rigid ceramic coating that resists cone breakup resonances well above its operating frequency, keeping midrange reproduction clean and undistorted through the critical vocal frequency band where dialogue intelligibility and musical presence are most sensitive to coloration.

Key Features

• 1" Titanium Dome LTS Tweeter with 90x90 Tractrix Horn: Linear Travel Suspension minimizes distortion at all output levels; the Tractrix Horn focuses high-frequency energy evenly across a 90x90 degree field for consistent coverage at every listening position, with extension to 25kHz.
• 3.5" Spun-Copper Cerametallic Woofer: Ceramic-coated aluminum cone delivers clean, low-distortion midrange and bass reproduction from 69Hz through the 2,200Hz crossover point, with the rigidity needed to resist resonance at the woofer-to-tweeter transition frequency.
• 91dB Sensitivity: Produces substantial output with modest amplifier power; a 20-watt-per-channel AV receiver is sufficient for most listening environments, while the 50W RMS and 200W peak capacity accommodates more powerful systems.
• Ultra-Slim 2.4" Depth: The shallowest dimension of the cabinet is only 2.4 inches, allowing the RP-140D to mount flush against the wall and complement any flat-panel television without creating visual bulk.
• Horizontal and Vertical Mounting: Dual 4-way keyholes on the rear panel support secure wall mounting in either orientation, enabling use as a vertically mounted left or right speaker, a horizontally mounted center channel, or a surround speaker in any wall position.
• Included Glass Base: A tempered glass stand is included for tabletop, bookshelf, or furniture placement as a no-drill alternative to wall mounting, supporting both horizontal and vertical orientation.
• Magnetic Wrap-Around Grille: Attaches and detaches without tools or clips, presenting a refined appearance when in place and revealing the distinctive spun-copper Cerametallic driver when removed.
• Single Binding Post Input: Accepts banana plugs, spade lugs, pin connectors, or bare wire for straightforward connection to any AV receiver or stereo amplifier.
• Bass Reflex Enclosure: Rear-ported tuning extends low-frequency output to a usable -3dB point of 69Hz from a cabinet only 12 inches tall and 6 inches wide.
• Matte Black Painted Finish: The non-reflective matte surface integrates visually with modern flat-panel televisions, dark-finished furniture, and contemporary interior design without drawing attention to the speaker enclosure.

Frequently Asked Questions

What is the Klipsch RP-140D?

The Klipsch RP-140D is a two-way, bass-reflex on-wall speaker from the Reference Premiere Designer On-Wall series, featuring a single 3.5" Cerametallic woofer and a 1" Titanium Dome LTS tweeter on a 90x90 Tractrix Horn. It delivers a frequency response of 69Hz to 25kHz, a sensitivity of 91dB, and handles up to 50W RMS. The cabinet measures 12 inches tall, 6 inches wide, and only 2.4 inches deep, and the speaker is sold individually for use in any channel position — front left, center, right, or surround.

How does the Klipsch RP-140D compare to the Klipsch RP-240D or the Monitor Audio SB-2?

The Klipsch RP-140D is the more compact sibling of the RP-240D, differing primarily in driver count: the RP-140D uses a single 3.5" Cerametallic woofer while the RP-240D uses dual 3.5" woofers, giving the RP-240D a slightly lower bass extension (67Hz vs. 69Hz) and 3dB more sensitivity (94dB vs. 91dB). Both use the identical LTS tweeter and Tractrix Horn, so high-frequency character and dispersion are the same. Compared to the Monitor Audio SB-2, the RP-140D provides a wider 90x90 degree horn-loaded dispersion pattern versus the Monitor Audio's conventional dome tweeter arrangement, which produces narrower off-axis high-frequency coverage. The RP-140D is the better choice for rooms with multiple listening positions spread across a wide seating area.

Can the Klipsch RP-140D be used as a surround channel speaker?

Yes, the RP-140D is specifically designed for use in any channel position including side surrounds, rear surrounds, and overhead height channels in multi-channel home theater systems. Its compact 12-inch height and 2.4-inch depth make it easy to mount at ear level on side walls or behind the seating position without intruding into the room. The 90x90 degree Tractrix Horn dispersion pattern covers a wide listening area from a single mounted position, and the shared Reference Premiere driver technology ensures seamless tonal integration with any other Reference Premiere speakers used in the same system.

What is the difference between the Klipsch RP-140D and the RP-240D?

The RP-140D uses a single 3.5" Cerametallic woofer and measures 12 inches tall, while the RP-240D uses dual 3.5" Cerametallic woofers and measures 16 inches tall. The dual-woofer RP-240D achieves 94dB sensitivity versus 91dB for the RP-140D, a 3dB difference representing roughly double the acoustic output per watt. The RP-240D also handles 75W RMS versus 50W RMS for the RP-140D. Both share the identical LTS tweeter, Tractrix Horn, 2.4-inch depth, and 6-inch width. The RP-140D is the preferred choice for tight installation spaces or surround positions where maximum output is less critical, while the RP-240D suits front-stage left and right positions where higher sensitivity and dynamic headroom are more important.

Where can I buy the Klipsch RP-140D in Toronto or Canada?

The Klipsch RP-140D is available at Vinyl Sound, an authorised Klipsch dealer in Toronto, Canada. Vinyl Sound carries the full Reference Premiere Designer On-Wall series and ships across Canada. Purchasing from an authorised Canadian dealer provides full manufacturer warranty support and access to personalized home theater system design guidance.

What amplifier or AV receiver does the Klipsch RP-140D need?

The RP-140D operates at 8 ohms nominal impedance and handles up to 50W RMS, making it compatible with any stereo amplifier or AV receiver with an 8-ohm speaker output. Its 91dB sensitivity means a 20-watt-per-channel receiver produces ample volume in a typical room. Klipsch recommends a quality AV receiver from manufacturers such as Denon, Marantz, Yamaha, or Onkyo that provides per-channel calibration and format decoding for optimal multi-channel performance. The single binding post accepts banana plugs, spade lugs, pin connectors, or bare wire.

Can I build a complete home theater system using only the RP-140D and other Reference Premiere Designer On-Wall speakers?

Yes, Klipsch designed the entire Reference Premiere Designer On-Wall series — the RP-140D, RP-240D, RP-640D, and RP-440D SB passive soundbar — to be used together in any combination. All models share the same LTS tweeter, Cerametallic woofer construction, Tractrix Horn geometry, and 2.4-inch cabinet depth, ensuring identical tonal character across every channel in the system. A common configuration pairs two RP-140D speakers as surround channels with the RP-440D SB as the front-stage LCR, creating a timbre-matched 3.0 to 5.1 system that mounts entirely on the wall without using any floor space.

Is the Klipsch RP-140D compatible with Dolby Atmos height channel configurations?

The RP-140D can be used as a height or elevation channel speaker in a Dolby Atmos or DTS:X system when mounted on the upper portion of side walls or the ceiling, though Klipsch's dedicated RP-500SA Dolby Atmos elevation module is engineered specifically for on-top-of-speaker or ceiling placement with the appropriate upward-firing driver angle. For wall-mounted height positions in rooms where ceiling placement is not practical, the RP-140D's 90x90 degree dispersion and shared Reference Premiere tonal character make it a compatible and cohesive addition to any Reference Premiere Atmos system.
