PSB celebrates ’70s style


PSB Speakers releases the Passif 50 Anniversary Edition loudspeaker in celebration of its 50-year milestone. The design and technologies of the Passif 50 model leverage five decades of dedicated research and pay homage to the early Passif II model first released in 1974. The Passif 50 will be shipping this September and retails at USD $2499/GBP £2499/EUR €2999/CAD $3299. The first 500 units sold of the Passif 50 will contain a handwritten letter from Paul Barton and includes a QR code with an offer to receive a gift pack that includes a cotton canvas backpack, double-walled water bottle, and commemorative keychain.

In 1974, PSB founder Paul Barton developed the Passif II at a time when his initial acoustic research had led to the establishment of PSB’s design philosophy. The Passif II was the first model to incorporate those principals and demonstrate the brand’s signature sound.

The Passif 50 features 1970s inspired elements like an open-grained walnut veneer cabinet, magnetically attached woven cloth grilles and dedicated stands. Other embellishments include a pull tab on the front grille, which sports the retro PSB logo and a rear-panel plaque adorned by a maple leaf.

The design of the Passif 50 mirrors its famous 1970s forefather but incorporates the most current flagship level components. The titanium dome tweeter employs a powerful neodymium magnet and ferrofluid damping, for higher output, improved power handling, and reduced distortion. A phase plug in front of the tweeter’s dome directs the tweeter’s output to ensure a wide and consistent dispersion well beyond the traditional listening window. 

The 6.5″ woofer and 8″ passive radiator have cast aluminum baskets that resist flexing, and filleted rubber surrounds that dampen cone resonances, resulting in smoother response and reduced distortion. Considerable engineering effort was invested in refining the interaction between the woofer and the passive radiator.

All joints in the heavily braced enclosure are mitred for improved fit and finish and reduced cabinet vibration. Featuring dual five-way binding posts, the Passif 50 can be bi-wired or bi-amped.
