PSB Speakers has launched the Passive 50 Anniversary Edition floor standing loudspeaker to celebrate its 50th anniversary. The design and technologies of the Passif 50 model are based on five decades of dedicated research and pay homage to the first Passif II model first released in 1974.

As a thank you to dedicated fans of the brand, the first 500 units sold of the Passive 50 will contain a handwritten letter from Paul Barton as well as a QR code with an offer to receive a gift box including a cotton canvas backpack , double – a wall water bottle and a commemorative key ring.

In 1974, PSB founder and chief designer Paul Barton developed the Passive II at a time when his early acoustic research had led to the establishment of PSB’s design philosophy. The Passive II was the first model to incorporate these principles and demonstrate what is now hailed as the brand’s “True to Nature” sound.

The Passif 50 features 1970s-inspired elements like an open-grain walnut veneer cabinet, magnetically attached woven fabric grilles, and dedicated brackets. The speaker evokes a sense of nostalgia with its retro details while being constructed with modern materials that align with current tastes. Other unique embellishments include a front grille tab, which features the retro PSB logo – originally hand-drawn by Paul in his high school geography class – and a leaf-adorned rear panel plaque. maple tree with an inscription that reads, “Passive 50 – 1972-2022.

The titanium dome tweeter uses a neodymium magnet and ferrofluid damping, for higher output, better power handling and reduced distortion. A phase tap in front of the tweeter dome directs the tweeter output to ensure wide and consistent dispersion. The result is a loudspeaker that creates a wide and deep soundstage with a very high-pitched image that is not dependent on a precise listening position. A felt pad surrounding the tweeter minimizes edge diffraction for better transparency and more stable imaging.

The woofer and passive radiator have cast aluminum baskets that resist bending and threaded rubber surrounds that dampen cone resonances, resulting in smoother response and reduced distortion. Considerable engineering effort has been invested in refining the interaction between the woofer and the passive radiator.

All joints in the heavily braced enclosure are mitered for improved fit and finish and reduced cabinet vibration. Equipped with two five-way binding posts, the Passif 50 can be bi-wired or bi-amplified.
