PSB Alpha P5 Compact Bookshelf Speakers - (Pair)

The PSB Alpha P5 Bookshelf Speakers Deliver Precision, Depth, and Natural Sound for Any Space

The PSB Alpha P5 Bookshelf Speakers are the epitome of refined, studio-quality audio engineered to fit effortlessly into any home or studio setting. Known for meticulous sound accuracy and robust performance, these speakers embody over 40 years of Canadian acoustic research and advanced design principles, bringing a legacy of precision and clarity to listeners.

Designed for Unmatched Sound Quality and Enhanced Performance

PSB’s Alpha P5 Bookshelf Speakers are a contemporary take on the legendary Alpha Series, offering users the latest advancements in sound engineering. At the heart of each P5 speaker is a custom-designed two-way system, featuring a 5.25” textured polypropylene woofer paired with a ¾” black anodized aluminium dome tweeter, uniquely positioned below the woofer to achieve flawless on and off-axis performance. This design optimizes the soundstage, immersing listeners in a natural, balanced acoustic experience whether in stereo or surround sound setups.

The Alpha P5 incorporates a refined crossover using the complex Linkwitz-Riley acoustic filter, a unique design within this class of speakers. This crossover precisely channels frequencies, resulting in crisp, distortion-free sound reproduction and a perfectly flat frequency response across high and low tones. Together with the rear-firing bass reflex port, this crossover ensures that bass frequencies reach incredible depths without overwhelming the clarity of mids and highs.

Precision-Tuned Components Built for High-Fidelity Audio

Engineered with a focus on high sensitivity and minimal distortion, the Alpha P5's black anodized aluminium dome tweeter utilizes ferrofluid cooling and a neodymium magnet to extend high-frequency response and reduce distortion. The integrated front waveguide further optimizes this tweeter, creating a layered, detailed sound profile that captures every subtle nuance in your audio.

The custom 5.25” woofer is built with textured polypropylene to minimize breakup, reinforced by dual-layer voice coils that enhance low-frequency handling. The woofer and tweeter combination ensures a remarkable 55Hz-21kHz frequency range and smooth integration across the crossover point, making the Alpha P5 the ideal choice for high-fidelity listening experiences that remain true to the original sound.

Robust Construction with Elegant Finishing Touches

The Alpha P5’s cabinet structure plays a crucial role in delivering its signature sound clarity and balance. Constructed with 12mm MDF for the cabinet sleeve and reinforced with thicker 25.4mm MDF on the front baffle, the cabinet is carefully braced to minimize unwanted resonance. PSB integrates flagship-level damping materials into the P5 design, precisely placed within the cabinet for optimal sound absorption and clarity.

Each Alpha P5 speaker is encased in a high-quality woodgrain vinyl finish, available in both Black Ash and Walnut. The acoustically-transparent, magnetically attached grilles allow the speaker’s natural tones to shine through without obstruction. Completing the build are five-way gold-plated binding post terminals for secure connectivity, suitable for a range of amplifier configurations.
