A 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. This creates a wide and deep soundstage with very acute imaging which isn’t reliant on a precise listening position. A felt pad surrounding the tweeter minimizes edge diffraction for improved transparency and more stable imaging.
The woofer and 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. The result is a state of perfect balance of their opposing forces.
While the Passif 50’s enclosure profile is similar to its classic forebears, there are several important differences. The Passif 50 is sold in mirror-imaged pairs. Having both tweeters on the inside of the soundstage results in improved imaging. 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.
In addition to their warm walnut veneer enclosures, woven cloth grilles, and dedicated stands, the Passif 50 has numerous anniversary edition aesthetic elements. These include a pull tab on the front grille, which sports PSB’s original logo, and a rear-panel plaque adorned by a maple leaf and an inscription that reads, “Passif 50 – 1972-2022.” With its cutting-edge technology and gorgeous retro design, the Passif 50 honours the past, embraces the future, and delivers sound that is True to Nature.
