Vocals are clear and expressive, instruments sound lifelike, and the overall presentation remains smooth and enjoyable—even during long listening sessions. Its precise imaging creates a surprisingly wide soundstage, making music and movies feel immersive rather than confined.
Ideal for smaller rooms, desktops, or minimalist systems, the Alpha P3 shines in near‑field listening, apartments, and compact home‑theater setups. When paired with a quality amplifier or a subwoofer, it delivers a full and satisfying performance that belies its modest dimensions.
Finished in a clean, modern design that blends effortlessly into any space, the PSB Alpha P3 Bookshelf Speaker is an excellent choice for listeners seeking true hi‑fi sound in a compact, affordable package—perfect as a first serious speaker or a high‑quality solution where space is at a premium.
Compact and versatile without sacrificing performance.
The Alpha P3 is a small two-way bookshelf speaker that connects to any stereo or home theatre system to fill the room with powerful, crystal-clear sound. Featuring a custom 4.5” woofer and aluminium dome tweeter that uses a waveguide to perfectly match the low and high frequencies for a smooth transition, the P3 delivers improved directivity and flattens the frequency response for a more natural sound. It also leverages specially textured woofer cones and a unique port tube design that uses bass flex to add back energy and extend the bass frequencies even lower and without any distortion.
Hear beautiful texture and detail
All new Alpha Series models employ a ¾” black anodized aluminium dome tweeter that extends the high-frequency response beyond the Alpha’s original measurements and minimizes distortion for a rich, balanced listening experience. A waveguide on the front of the tweeter works to perfect on and off-axis performance while smoothing the response for improved resolution and detail. The ferrofluid cooled tweeter on the P3 has also been precision engineered to sit below the woofer to provide precise stereo imaging at any height.
Powerful woofer with dual layer voice coils
At the heart of every good speaker is a great woofer that produces low distortion and high output levels. With the new Alpha Series, the 4.5” woofer employs dual layer voice coils with a very powerful magnet structure and a cone that is made from a special textured polypropylene compound that prevents breakup. With bass reflex loaded through Paul’s original port tube design from the ’70s, the woofer adds back wave energy to extend the bass response and improve efficiency down to 43Hz.
Custom-built and perfected
The Alpha Series’ new crossover wasn’t custom designed to simply just direct low and high frequencies to the woofer and tweeter. It was re-engineered to control the directivity and flatten the frequency response while utilizing an unusually complex acoustic Butterworth low-pass filter that is designed to get a perfect blend between the drivers and keep distortion at its lowest even at high volumes.
Unique modular cabinet design
The P3 has a unique combination of wall thickness and bracing to control resonances and provide a perfect platform for the driver components. The P3 cabinet’s internal damping material was first used in PSB’s most high-end models, and has now been adopted by the Alphas and positioned precisely for optimum effectiveness. A premium woodgrain vinyl finish and chrome front baffle highlights combine with magnetically attached grilles to provide a rich and timeless design.
