PSB PWM2 5-Driver On-Wall Speaker

PSB PWM2 On-Wall Speaker at Vinyl Sound Buffalo NY

The PSB PWM2 is a five-driver 3-way on-wall speaker built around a 1-inch titanium dome tweeter with ferrofluid and Neodymium magnet, two 3-inch carbon fibre midrange drivers with rubber surround and cast basket, and two 4-inch carbon fibre woofers with rubber surround and cast basket, all housed in a bass reflex MDF cabinet measuring 36 inches wide by 6.5 inches tall by 3.38 inches deep. Available at Vinyl Sound in Buffalo, New York, the PWM2 is a mid-series model in PSB's PWM on-wall speaker line, positioned below the seven-driver PWM3 flagship and sharing the same 3-way driver layout and cabinet depth while offering a more compact 36-inch cabinet footprint. The bass reflex design extends low-frequency output to 70Hz (±3dB) with a -10dB point at 40Hz, and the titanium tweeter covers the upper frequency range to 23,000Hz. The PWM2 delivers 86dB anechoic sensitivity into a nominal 8-ohm load. The four-layer voice coils on the midrange and woofer drivers provide high power handling capacity and low impedance consistency across the driver's operating range. The included wall mount bracket supports both horizontal and vertical installation — horizontal for center or L/R channels positioned relative to a display, vertical as a column speaker for L/R or surround channels beside a screen. The bracket is not rated for ceiling mounting. Satin Black and Satin White finishes allow the PWM2 to integrate with the wall surface or the display surround. The PWM2 is part of Vinyl Sound Buffalo's full speaker collection, which includes on-wall, in-wall, in-ceiling, outdoor, powered, and floorstanding speakers from leading audio brands.

Titanium Tweeter with Neodymium Magnet, Carbon Fibre Midrange, and Carbon Fibre Woofers

The PWM2's 1-inch titanium dome tweeter uses a Neodymium magnet motor rather than the ferrite magnet found in lower-cost driver designs. Neodymium magnets produce a stronger magnetic field per unit of magnet mass, which allows the tweeter motor to be smaller and lighter without reducing the magnetic flux density in the voice coil gap. A stronger flux density produces higher motor efficiency — more acoustic output per watt of input — contributing to the PWM2's 86dB sensitivity figure. Ferrofluid fills the voice coil gap to conduct heat away from the coil and into the magnet structure, reducing thermal compression at sustained output levels. The two 3-inch carbon fibre midrange drivers and two 4-inch carbon fibre woofers share the same cone material: carbon fibre composite. Carbon fibre cones are stiff and light, with a higher stiffness-to-mass ratio than glass-filled polypropylene or paper cones of comparable size, which pushes the first cone breakup resonance above the driver's intended operating range and reduces high-order distortion products. Cast baskets on all four cone drivers provide a rigid, dimensionally stable chassis that maintains precise voice coil-to-gap alignment under the mechanical forces generated during normal speaker operation.

Four-Layer Voice Coils, Bass Reflex Design, and Wall Installation

The PWM2's midrange and woofer drivers use four-layer voice coils — coils wound in four separate layers of wire on the same voice coil former rather than the two-layer configuration common in budget speaker drivers. Four-layer winding increases the total length of wire in the gap, which reduces the DC resistance per unit of motor force and improves the power handling capacity of the driver. More wire layers in the gap also increases the coil's thermal mass, which absorbs more energy before the coil temperature rises to a level that affects adhesive bonding or wire insulation integrity. The bass reflex cabinet uses one or more tuned ports to extend low-frequency output below the woofers' free-air resonance frequency, enabling the PWM2 to reach 40Hz (-10dB) from a cabinet only 3.38 inches deep and 6.5 inches tall. The MDF cabinet provides a dense enclosure material with high damping of internal panel resonances. The wall mount bracket installs to the wall first, then the PWM2 cabinet attaches to the bracket. Horizontal mounting positions the 36-inch cabinet width along the wall; vertical mounting positions the 6.5-inch width as a narrow column 36 inches tall. The bracket is not designed for ceiling installation.

Frequently Asked Questions

How does the PWM2 differ from the PWM3?

The PWM2 and PWM3 share the same cabinet depth (3.38 inches), height (6.5 inches), sensitivity (86dB anechoic / 89dB listening room), impedance (8 ohms nominal / 6 ohms minimum), and 3-way driver topology with titanium dome tweeter, carbon fibre midrange, and carbon fibre woofers. The key differences are driver count and cabinet width. The PWM3 uses four 4-inch woofers in a 48-inch cabinet and extends bass to 60Hz (±3dB) with a -10dB point at 35Hz, and its titanium tweeter reaches 35,000Hz. The PWM2 uses two 4-inch woofers in a 36-inch cabinet and extends bass to 70Hz (±3dB) with a -10dB point at 40Hz, and its tweeter reaches 23,000Hz. The PWM2 is 12 inches shorter than the PWM3, which makes it a better fit for narrower wall spaces, smaller displays, or rooms where a 48-inch speaker is too wide for the available mounting position. For maximum bass extension and the highest output ceiling, the PWM3 is the stronger performer; for installations where the PWM3's 48-inch footprint is excessive, the PWM2 provides the same cabinet depth, the same sensitivity, and comparable performance in a more compact 36-inch format.

What is a four-layer voice coil and why does the PWM2 use one?

A voice coil is a cylindrical coil of wire attached to the speaker cone that moves in and out of a magnetic gap in response to the audio signal. A four-layer voice coil has four separate layers of wire wound concentrically on the same former, as opposed to the two-layer design used in lower-cost drivers. More wire layers increase the total length of conductor in the magnetic gap, which reduces the DC resistance per unit of generated force (improving the motor's efficiency) and increases the coil's thermal mass — the coil can absorb more energy before reaching temperatures that risk adhesive failure or wire insulation damage. Four-layer voice coils are also associated with higher linear excursion capability because the taller, more mechanically stable coil is better controlled by the spider and surround at large excursion values. In the PWM2's midrange and woofer drivers, four-layer voice coils contribute to the high power handling capacity appropriate for a home theater speaker that may see significant sustained power from a receiver or amplifier driving a full surround sound system at high levels.

What is a Neodymium magnet tweeter and how does it differ from a standard tweeter?

Neodymium is a rare earth element used to make permanent magnets that are significantly stronger than conventional ferrite (ceramic) magnets at the same physical size and mass. In a speaker tweeter, the magnet's job is to create a strong, stable magnetic field in the gap where the voice coil operates. A stronger field produces more force on the voice coil per unit of current, which means more acoustic output for a given amplifier power — higher sensitivity. A Neodymium magnet produces the same or greater magnetic flux density as a ferrite magnet many times its size, which allows the tweeter motor assembly to be smaller and lighter without sacrificing sensitivity. In the PWM2's 1-inch titanium dome tweeter, the Neodymium magnet combined with ferrofluid cooling allows the tweeter to achieve high sensitivity (contributing to the PWM2's 86dB overall sensitivity) while maintaining consistent performance at elevated power levels across a home theater listening session.

Can the PWM2 be used as a center channel speaker?

Yes. The PWM2 is designed to function as a center channel speaker when mounted horizontally below or above a display. In horizontal orientation, the speaker is 36 inches wide and 6.5 inches tall, with its driver array — tweeter, two midranges, and two woofers — distributed across the 36-inch width. This driver arrangement produces a horizontal radiation pattern appropriate for center channel dialogue and effects reproduction. Using PWM2 units for all channels in a home theater — left, center, right, and surround — provides a tonally matched speaker system where all channels have the same frequency response, sensitivity, and driver complement. A tonally matched system produces smoother panning and transitions as audio effects move from the front stage to the surrounds and back, which is particularly noticeable in action film soundtracks and multichannel music mixes.

What bass extension does the PWM2 achieve and how does the bass reflex design work?

The PWM2 extends bass to 70Hz (±3dB) and 40Hz (-10dB) — a significant low-frequency output range from a speaker only 3.38 inches deep. A bass reflex enclosure adds one or more ports to the sealed cabinet volume. The port is a tuned acoustic resonator — a tube of specific length and diameter whose resonant frequency is set below the woofer's free-air resonance. At and near the port's tuning frequency, the port aperture itself radiates acoustic output in-phase with the woofer cone's output, augmenting the bass below the frequency where the woofer alone would begin rolling off. The combined woofer and port output extends the low-frequency response lower than an equivalent sealed enclosure of the same internal volume. The trade-off is that below the port tuning frequency, the woofer cone is no longer controlled by the enclosure pressure, and excursion rises rapidly — which is why a bass reflex speaker's -10dB point of 40Hz is not the same as a flat response to 40Hz. The PWM2's dual 4-inch woofers provide the combined cone area needed to drive the bass reflex loading effectively from the slim 3.38-inch cabinet depth.

How many PWM2 units do I need for a complete home theater system?

A basic 5.1 home theater system using PWM2 speakers for all channels requires five PWM2 units: one as a center channel (horizontal, below or above the display), two as left and right front channels (horizontal or vertical beside the display), and two as left and right surround channels (typically mounted on the side or rear walls). A 7.1 system adds two additional PWM2 units for left and right back surround positions. All five or seven PWM2 units can use the same satin black or satin white finish, maintaining a consistent visual appearance across the system. A subwoofer handles bass reproduction below 80Hz in a .1 surround configuration — the PWM2's bass reflex extension to 40Hz supplements the subwoofer overlap range.
