Big sound, small footprint

Unlike many bookshelf speakers, the Alpha P3's compact dimensions (H22cm x W13cm x D17cm) make it truly shelf-friendly. It's small enough to fit comfortably on most bookshelves. But don't be fooled by its small footprint. The Alpha P3 delivers room-filling audio that defies their compact size. With custom 4" woofers and precision-engineered components, they punch above their weight class to provide an experience that exceeds expectations.

Impressive Performance

Experience the Alpha P3's expansive soundstage. This compact marvel features a custom 4" woofer and aluminum dome tweeter with a front waveguide, ensuring precise, natural reproduction. Textured woofer cones and a unique port tube design deliver deep, resonating lows without distortion. Meanwhile, its aluminum dome tweeter allows it to hit higher notes with precision and clarity. Even at high volumes, the Alpha P3 maintains its composure and refinement across the scale.

Precision Engineered

The Alpha P3 results from meticulous precision engineering, leaving no stone unturned. It features an advanced Acoustic Linkwitz-Riley filter that intricately manages frequencies. This filter and a re-engineered crossover controls the sound’s direction and response, even at high volumes, keeping distortion at bay. The outcome is crystal-clear, high-quality audio that defies expectations. Experience the Alpha P3 and be amazed by its unmatched precision and clarity.

Unique Cabinet Design

A classic look, improved by cutting-edge technology. The P3's cabinet combines wall thickness and bracing to control resonances, providing an optimal platform for driver components. Internal damping material, borrowed from PSB's high-end models, enhances its performance even further. The premium woodgrain vinyl finish (available in American Walnut or Black Ash), chrome front baffle, and magnetically attached grilles exude a timeless and elegant design.
