Klipsch PRO-18RW In-Wall Speaker (Each) at Vinyl Sound Toronto Canada

The PRO-18RW is a 2-way in-wall speaker from Klipsch (Indianapolis, Indiana, USA), available at Vinyl Sound in Toronto, Canada. Part of Klipsch's Professional Series Reference architectural lineup, it uses the same acoustic components and horn design as the Klipsch Reference box speaker series to bring Reference-grade sound to distributed audio and home theater installations. An 8" Injection Molded Graphite (IMG) Woofer paired with a 1" Pivot Aluminum Dome Tweeter mated to a 90° x 90° ABS Tractrix Horn delivers a measured frequency response of 56Hz to 23kHz (+/-3dB) at a high 95dB sensitivity and 8 ohms, with 50W RMS and 200W peak power handling across a symmetrical 90° x 90° coverage pattern. Controlled Dispersion Technology allows the tweeter to be aimed up to 15° in any direction for on-axis frequency response optimization to off-center listening positions. The exclusive SecureFit Installation System prevents overtorquing during mounting, and the package includes both square and round bezel-free magnetic paintable grilles plus a magnetic PVC paint shield for construction and renovation protection.

True Klipsch Reference Acoustics: IMG Woofer and Tractrix Horn

The PRO-18RW draws from Klipsch's Reference speaker series, using the same 8" Injection Molded Graphite woofer and Tractrix horn design as the Reference box speaker lineup. IMG woofers are produced by injecting graphite-infused polymer under high pressure into a precision mold, creating a cone with exceptional stiffness and internal damping in a single repeatable process that eliminates the cone variability associated with hand-formed paper or composite cones. The graphite fiber reinforcement within the polymer matrix adds rigidity without increasing mass, allowing the 8" driver to move with speed and accuracy while maintaining low distortion at high excursion levels across the 56Hz to 23kHz operating range. The 1" aluminum dome tweeter couples into a 90° x 90° ABS Tractrix horn, focusing high-frequency energy into a controlled, predictable dispersion pattern for consistent tonal balance from all seating positions in the room. At 95dB sensitivity, the PRO-18RW ranks among the most efficient in-wall speakers available, producing substantial output from the modest per-channel power available in multi-zone whole-home audio distribution systems, where amplifier power is typically shared across multiple rooms simultaneously.

Controlled Dispersion Technology and SecureFit Installation

The PRO-18RW's 1" aluminum dome tweeter pivots up to 15° in any direction via Klipsch's Controlled Dispersion Technology. This is more flexible than the +/-15° single-axis pivot found on many in-wall speakers, allowing the installer to aim the tweeter's 90° x 90° coverage pattern both horizontally and vertically toward the primary listening position regardless of where the speaker must be placed on the wall. The result is better on-axis frequency response for off-center listening positions, more direct high-frequency energy at the listener's ears, and less reflected sound from room boundaries, which contributes to clearer imaging and more natural vocal reproduction. The SecureFit Installation System prevents the most common in-wall speaker installation failure: overtorquing the mounting dog legs. SecureFit dog legs engage by hand to a factory-preset clamping force automatically, then the speaker module fastens to the bezel with machine screws for a mechanically stiffer and acoustically more stable connection than drywall-screw mounting achieves. Both a square and a round bezel-free magnetic paintable grille are included in the box, and a magnetic PVC paint shield protects the driver during painting or construction work.

Key Features

• 8" Injection Molded Graphite (IMG) Woofer: High-pressure injection molding with graphite fiber reinforcement produces a stiff, well-damped cone with low mass for accurate, low-distortion bass and midrange reproduction from 56Hz through the crossover frequency, using the same driver technology as Klipsch's Reference box speaker lineup.
• 1" Pivot Aluminum Dome Tweeter with 90° x 90° ABS Tractrix Horn: The aluminum dome tweeter mated to a Tractrix horn focuses high-frequency energy into a controlled 90° x 90° pattern for consistent tonal balance across the listening area, with Tractrix geometry maximizing the efficiency of energy transfer from driver to room.
• Controlled Dispersion Technology: The tweeter pivots up to 15° in any direction, providing horizontal and vertical aiming flexibility that allows the installer to optimize on-axis frequency response toward off-center listening positions, overcoming the common constraint that in-wall speaker placement is dictated by stud bay location rather than acoustic ideal.
• 95dB Sensitivity at 8 Ohms: Exceptional efficiency allows the PRO-18RW to produce substantial output from very modest amplifier power, making it an excellent match for multi-zone whole-home audio distribution systems where per-channel power is limited and long speaker wire runs further reduce delivered power.
• SecureFit Modular Installation System: Dog legs engage by hand to a factory-preset clamping force, eliminating overtorquing. The speaker module then fastens to the bezel using machine screws for a mechanically stiffer and more acoustically stable installation than conventional drywall-screw mounting methods.
• Both Square and Round Bezel-Free Magnetic Grilles Included: A square and a round powercoated magnetic steel grille are both included in the box, providing the visual profile that best suits the installation environment without an additional purchase. Both grilles are paintable to match any wall finish and attach without visible hardware.
• Magnetic PVC Paint Shield Included: A magnetic paint shield covers the speaker module during wall painting or construction work to protect the IMG cone, aluminum dome tweeter, and horn from paint splatter and construction dust without requiring grille removal.
• Infinite Baffle ABS Enclosure: The wall cavity serves as the acoustic working environment at 3.9" mounting depth. Compatible with the optional IK-800-W or IK-800-W II installation kit for new construction framing applications (both sold separately).

Frequently Asked Questions

What is the Klipsch PRO-18RW?

The Klipsch PRO-18RW is a 2-way in-wall speaker from Klipsch's Professional Series Reference architectural lineup, featuring an 8" Injection Molded Graphite woofer and a 1" pivot aluminum dome tweeter mated to a 90° x 90° ABS Tractrix horn. It delivers a frequency response of 56Hz to 23kHz at 95dB sensitivity and 8 ohms, with 50W RMS and 200W peak power handling. Controlled Dispersion Technology allows tweeter aiming up to 15° in any direction, and the SecureFit Installation System, both square and round bezel-free magnetic paintable grilles, and a magnetic PVC paint shield are all included.

How does the Klipsch PRO-18RW compare to the PRO-180RPW and the Polk Audio 80RT?

The Klipsch PRO-18RW and PRO-180RPW are both 8" in-wall speakers from Klipsch's Professional Series but belong to different acoustic lineages. The PRO-18RW uses an IMG woofer and aluminum dome tweeter drawing from the Klipsch Reference series, reaching 95dB sensitivity. The PRO-180RPW uses a Cerametallic woofer and titanium dome tweeter with Hybrid Cross Section Tractrix horn from the Reference Premiere series, at 96dB sensitivity and deeper 52Hz bass extension versus the PRO-18RW's 56Hz. The PRO-18RW includes both square and round grilles in the box, while the PRO-180RPW includes one rectangular grille. The PRO-18RW's Controlled Dispersion Technology also allows multi-axis tweeter aiming rather than the single-axis horn pivot of the PRO-180RPW. Compared to the Polk Audio 80RT, the Klipsch PRO-18RW's 95dB sensitivity substantially exceeds the Polk's rating, and the Tractrix horn provides more controlled directivity and higher efficiency than the Polk's conventional dome tweeter.

What is Controlled Dispersion Technology and how does it differ from a standard pivoting tweeter?

Controlled Dispersion Technology on the PRO-18RW allows the 1" aluminum dome tweeter assembly to pivot up to 15° in any direction, meaning it can be aimed horizontally, vertically, or diagonally toward the listening position. A standard pivoting tweeter on many in-wall speakers pivots only along a single horizontal axis, which corrects for listening positions that are off-center left or right of the speaker but does not address positions that are above or below the ideal tweeter axis. The multi-directional pivot of Controlled Dispersion Technology resolves both horizontal and vertical misalignment between the speaker's installation position and the primary listening seat, making it a more complete solution for installations where the speaker location on the wall is constrained by stud bay placement and the listening position is at a difficult angle in both axes simultaneously.

What is an Injection Molded Graphite woofer and why is it used?

An Injection Molded Graphite woofer is produced by injecting a graphite fiber and polymer compound into a precision mold under high pressure. The graphite fiber reinforcement within the polymer matrix adds rigidity without significantly increasing cone mass, producing a cone that is stiffer and better-damped than conventional paper or unfilled polymer cones of the same dimensions. The injection molding process also produces a highly consistent cone geometry from unit to unit, improving driver-to-driver matching in multi-speaker distributed audio systems. In the PRO-18RW, the 8" IMG cone delivers low-distortion bass and midrange reproduction across the 56Hz to 23kHz operating range with the same tonal character as the Reference box speaker series from which the design is drawn.

Why are both a square and a round grille included with the PRO-18RW?

Klipsch includes both a square and a round bezel-free magnetic grille with the PRO-18RW to provide installation flexibility without requiring an additional purchase. In rooms with modern minimalist interiors or where the speaker is installed adjacent to square architectural elements such as recessed panels or rectangular wall features, the square grille provides a more consistent visual integration. In rooms where the speaker is installed near circular elements such as recessed can lights, or where a round profile is preferred for aesthetic reasons, the round grille offers a better visual fit. Both grilles attach magnetically without visible hardware, accept standard interior wall paint for wall-color matching, and can be removed without tools for driver access or servicing.

Where can I buy the Klipsch PRO-18RW in Toronto or Canada?

The Klipsch PRO-18RW In-Wall Speaker is available at Vinyl Sound, an authorized Klipsch dealer in Toronto, Canada. Vinyl Sound carries the full Klipsch Professional Series Reference architectural speaker lineup and can advise on system configuration, whole-home audio zone design, amplifier matching, and installation accessory selection including the optional IK-800-W or IK-800-W II installation kits for new construction and retrofit projects across the Toronto area and across Canada.

What amplifier does the Klipsch PRO-18RW require?

The Klipsch PRO-18RW requires any external amplifier capable of stable 8-ohm operation, with a recommended amplifier power of 100W per channel and a maximum continuous power handling of 50W RMS. The 95dB sensitivity means the speaker produces meaningful volume from just a few watts of input, so a 30W to 100W per channel multi-zone distribution amplifier from brands such as Sonos Amp, Denon HEOS Amp, Marantz M1, Russound, or similar is entirely sufficient for whole-home audio applications. For home theater use, any modern AV receiver rated at 50W or more per channel at 8 ohms will drive the PRO-18RW comfortably at reference listening levels in standard room sizes.
