Crystal-Clear Sound Within Your Reach

The Alpha P3 stands out for its ability to produce rich, balanced sound. The 0.75-inch black anodized aluminum dome tweeter offers an extended high-frequency response, minimizing distortion for an exceptional listening experience. Additionally, a front waveguide on the tweeter contributes to outstanding performance, whether you’re directly in front of the speakers or slightly off-axis.

The 4-inch textured polypropylene woofer with rubber surround ensures powerful, precise bass. Thanks to a bass-reflex cabinet design with a rear-firing port, the P3 adds energy to low frequencies, extending them even lower without any distortion. When you’re listening to music or watching movies, you can enjoy the full range of sounds, from deep lows to crystal-clear highs.

Technology in Service of Sound

To deliver an exceptional listening experience, the PSB Speakers Alpha P3 incorporates cutting-edge technologies. The ferrofluid-cooled tweeter has been carefully designed to sit below the woofer, ensuring precise stereo imaging at any height. The woofer’s dual-layer voice coils reduce distortion and allow for high output levels.

The Alpha series crossover has been redesigned to control directivity and flatten frequency response. It uses a complex Linkwitz-Riley acoustic filter design to achieve a seamless blend between the speakers and keep distortion at its lowest, even at high volumes. This allows you to enjoy high-quality sound, regardless of the volume level.

A Design That Matters

In addition to its exceptional audio performance, the Alpha P3 also stands out for its elegant design. The speaker features a unique combination of wall thickness and bracing to control resonances and provide a solid platform for the speaker components. The cabinet’s internal damping material was first used in PSB’s high-end models, ensuring optimal efficiency.

The premium wood-grain vinyl finish and chrome front deflectors give the speaker a timeless, elegant look that will seamlessly integrate into any decor. Plus, the removable acoustically transparent magnetic grilles add a touch of sophistication while protecting the speakers.
