PSB Passif 50 loudspeakers, walnut

The Passif 50 leverages five decades of acoustics research and design experience. Since the early 1970s, PSB has been an active participant in the world-famous acoustics program at Canada’s National Research Council. An engineering team led by PSB founder and chief designer Paul Barton measures prototypes in the NRC’s anechoic chamber, then correlates these measurements with extensive subjective listening tests. This process has led to an unbroken series of products acclaimed by listeners and reviewers for their tonal fidelity, spatial realism, and effortless dynamics – even at high listening levels. The Passif 50 Standmount Loudspeaker is the latest product of PSB’s time-tested design process.
