PSB PWM3 Three-Way On-Wall Speaker at Vinyl Sound Toronto Canada

The PWM3 is the flagship three-way passive on-wall speaker from PSB Speakers (Pickering, Ontario, Canada), available at Vinyl Sound in Toronto, Canada. The pinnacle of PSB's Performance Wall Mount Series, the PWM3 houses seven custom-engineered drivers in a dual-ported MDF cabinet just 3.375 inches deep: a 1-inch titanium dome tweeter with ferrofluid cooling and neodymium magnet, two 3-inch carbon fibre cone midrange drivers in dedicated chambered enclosures, and four 4-inch carbon fibre cone woofers — all built with four-layer voice coils and cast baskets. It delivers a frequency response of 60 Hz to 35 kHz (±3 dB) with LF extension to 35 Hz (-10 dB), at 8 ohms nominal and 86 dB anechoic sensitivity. Sized at 48 inches tall to complement an 85-inch flat-panel television, the PWM3 mounts vertically or horizontally and serves as a left and right pair, centre channel, or any channel in a full on-wall surround system. Available in Satin Black and Satin White.

Seven-Driver Three-Way Architecture and Dual-Ported Cabinet

The PWM3 expands on the PWM2's driver architecture by adding a second pair of 4-inch carbon fibre woofers, bringing the total driver count to seven and enabling the bass output and dynamic headroom of a conventional floor-standing tower speaker from a 3.375-inch-deep on-wall enclosure. The four woofers operate in two pairs, each pair loaded by one of the cabinet's two rear-firing ports, a dual-ported arrangement that allows PSB to tune the bass alignment for maximum extension with controlled rolloff while preserving the slim profile. The two 3-inch midrange drivers are mounted in dedicated subdivided chambers within the cabinet, isolating their acoustic environment from the woofer cavities and preventing bass-frequency pressure from modulating the midrange drivers' output. This three-way architecture allows the PWM3 to extend the high-frequency response to 35 kHz — beyond the typical 20–23 kHz ceiling of most two-way on-wall designs — while maintaining the lower distortion that a dedicated midrange driver achieves by removing bass frequencies from its operating range.

Carbon Fibre Drivers with Four-Layer Voice Coils and Paul Barton Voicing

Every driver in the PWM3 uses carbon fibre cone construction, a material that delivers exceptional stiffness-to-mass ratio — stiffer than polypropylene composites, yet lighter than aluminium — resulting in lower colouration, better transient response, and higher power handling at the cone's breakup frequency. All drivers are built with four-layer voice coils wound on cast alloy formers with powerful neodymium or conventional magnets, mounted in rigid cast baskets that minimise motor flex under load. The 1-inch titanium dome tweeter uses the same ferrofluid-cooled dome design developed for the PWM series, with a front waveguide that controls horizontal dispersion and ensures a smooth transition from the midrange drivers at the crossover frequency. Final voicing was performed by the PSB design team mentored by PSB founder Paul Barton, applying the same True-to-Nature acoustic philosophy used across PSB's Imagine and CustomSound speaker ranges.

Frequently Asked Questions

What is the PSB PWM3?

The PSB PWM3 is a three-way passive on-wall speaker from PSB Speakers, designed and voiced in Pickering, Ontario, Canada. It is the flagship model in the Performance Wall Mount Series, housing seven drivers — one 1-inch titanium dome tweeter, two 3-inch carbon fibre midrange drivers, and four 4-inch carbon fibre woofers — in a dual-ported MDF cabinet 3.375 inches deep. It delivers a frequency response of 60 Hz to 35 kHz (±3 dB) at 8 ohms nominal, sized at 48 inches tall to complement an 85-inch flat-panel television.

How does the PSB PWM3 compare to the Sonance Mag Series and Definitive Technology W Studio?

The PSB PWM3, Sonance Mag Series, and Definitive Technology W Studio are all premium on-wall speaker solutions targeting design-conscious custom installation environments. The Definitive Technology W Studio integrates a powered subwoofer section alongside its passive midrange and tweeter array, adding amplified bass without a separate subwoofer. The Sonance Mag Series offers a wider range of slim on-wall formats designed primarily for architectural integration. The PWM3 differentiates through its seven-driver three-way architecture — the only PSB on-wall design with dedicated midrange drivers in subdivided chambers — dual-ported bass alignment reaching 35 Hz (-10 dB), carbon fibre cone construction across all drivers, 35 kHz high-frequency extension, and a 48-inch height specifically proportioned to flank an 85-inch television for a cohesive front-stage visual integration.

What is the advantage of the three-way design over the PWM1 and PWM2?

The PWM3's three-way design adds a dedicated pair of 3-inch midrange drivers in subdivided chambers between the tweeter and the four woofers, freeing each driver to operate over a narrower frequency range where it performs with lower distortion and better cone control. The woofers concentrate on bass reproduction below the midrange crossover point, the midrange drivers handle the critical vocal and instrument frequencies without bass-frequency excitation, and the tweeter operates only above the midrange crossover. This results in lower intermodulation distortion across all three frequency ranges and more accurate reproduction of complex, dynamically demanding content. The additional woofer pair also adds bass output and dynamic headroom compared to the PWM2's dual-woofer configuration.

Can the PSB PWM3 be used without a subwoofer?

The PWM3's LF extension reaches 35 Hz (-10 dB) — well below the standard 80 Hz home theatre crossover point — making it more capable of producing bass frequencies than most on-wall speakers at any price. In two-channel music listening, the PWM3 can operate effectively without a subwoofer in smaller to medium-sized rooms. For home theatre use at cinema output levels, or in larger open-concept spaces, a subwoofer remains recommended to reproduce the lowest frequencies in film soundtracks with adequate dynamic range. PSB's CSIR SUB In-Room Subwoofer and CSIW SUB28 in-wall subwoofer are natural aesthetic partners for a complete on-wall or in-wall PSB system.

Can the PWM3 be mounted horizontally as a centre channel?

Yes. The PWM3 includes a wall mount bracket that supports both vertical and horizontal installation orientations. When mounted horizontally beneath a wall-mounted display, the PWM3 functions as a centre channel speaker. Its 48-inch width when horizontal covers most of the horizontal span of an 85-inch television for a visually proportionate installation. The three-way driver architecture and subdivided midrange chambers maintain consistent tonal performance in both orientations, making the PWM3 equally capable as a horizontal centre channel and as a vertical left or right speaker.

Is the PSB PWM3 compatible with the PWM1 and PWM2 for a complete surround system?

Yes. PSB designed the PWM1, PWM2, and PWM3 as a tonally matched family for use together in complete on-wall surround systems. The PWM3 is sized for an 85-inch television, the PWM2 for a 70-inch display, and the PWM1 for a 55-inch display, allowing an installer to scale each speaker's height to the available wall space for the left, centre, right, and surround positions. All three models share the same tweeter and carbon fibre driver technology and are voiced to the same tonal target, ensuring seamless transitions across channels in film soundtracks and music.
