Frequently Asked Questions - Passif 50 PSB

What is the frequency response of the PSB Passif 50?

The PSB Passif 50 has a frequency response of 50 Hz to 20 kHz ±3 dB on axis, with a low-frequency cutoff of 30 Hz at -10 dB.

Can I use the Passif 50 without the dedicated stands?

Yes, but the dedicated stands are designed to optimize performance and aesthetics. Without stands, the speaker dimensions are 660 mm H × 280 mm W × 254 mm D.

Is the Passif 50 bi-wirable or bi-ampable?

Yes, the Passif 50 features dual five-way gold-plated binding posts that allow both bi-wiring and bi-amping.

What type of tweeter does the Passif 50 use?

It uses a 1-inch titanium dome tweeter with a neodymium magnet and ferrofluid damping for improved power handling and reduced distortion.

How should I clean the walnut veneer and grille?

Use a soft, dry cloth for the veneer. For the grille, gently vacuum with a brush attachment or use a lint roller. Avoid liquids and abrasives.

What is the recommended amplifier power for the Passif 50?

PSB recommends an amplifier with 30 to 200 watts per channel. The speaker has a sensitivity of 87 dB (anechoic) and 89 dB (listening room).

Does the Passif 50 include floor stands?

Yes, dedicated stands are included with the Passif 50, designed to match the speaker's aesthetic and ensure proper height and stability.

What is the impedance of the Passif 50?

Nominal impedance is 6 ohms, with a minimum of 4 ohms. It is compatible with most quality amplifiers.

How does the Passif 50 differ from the original Passif II?

The Passif 50 updates the classic design with modern components including a titanium tweeter, advanced crossover, and passive radiator for deeper bass, while retaining the retro look and open-grained walnut finish.

What is the warranty on the PSB Passif 50?

Warranty details vary by region. Typically, PSB offers a limited warranty; check with your authorized dealer or PSB for specific terms.

PSB Passif 50 Stand Loudspeaker

Created to celebrate the 50th anniversary of PSB, the Passif 50 Standmount Loudspeaker harkens back to the legendary Passif II model that cemented the brand's reputation for performance and value. The Passif 50 follows the design of its 1970's ancestor while utilizing the latest technologies and leveraging five decades of acoustics research and design experience. The Passif 50 is the latest application of PSB's True to Nature design philosophy.

The Science of Sound

Introduced in 1974, the Passif II was the culmination of years of R&D work at the National Research Council in Ottawa, Canada by PSB founder and chief designer Paul Barton. To this day, Barton and his colleagues measure their designs in the NRC's anechoic chamber and correlate their measurements with extensive subjective listening tests. This process has led to an unbroken series of products acclaimed by listeners and reviewers for their tonal accuracy, spatial realism, and freedom from distortion. Paul Barton personally oversees the final acoustic design of every PSB loudspeaker. The latest product of this process is the Passif 50, a classic standmount design that accurately reproduces music exactly as the creators intended – without colouration of any kind.

Evoking an Era

With open-grained walnut veneer enclosures, magnetically attached woven cloth grilles, and dedicated stands, PSB's Passif 50 Standmount Loudspeakers evoke the storied history of one of the world's great audio brands. Details alluding to the brand's heritage include a pull tab on the front grille, which sports PSB's original logo, a rear-panel plaque adorned by a maple leaf and an inscription that reads, "Passif 50 – Anniversary Edition – 1972-2022."

Cutting Edge Design

Employing a 1" dome tweeter, 6.5" paper cone woofer and 8" passive radiator, the Passif 50 has a similar driver complement to the original Passif models. But the Passif 50 enhances and optimizes the classic standmount design, incorporating the most current PSB componentry and technology trickled down from PSB's flagship models.

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 result is a speaker which 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.

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 is bi-wirable and bi-ampable. With its innovative technology and gorgeous retro design, the PSB Passif 50 Standmount Loudspeaker honours the past, embraces the future, and delivers sound that is True to Nature.
