Award-Winning PSB 500 Bookshelf Speakers – Made in Canada

Paul Barton founded PSB in St. Jacobs, Ontario, in the summer of 1972 with two high-school friends, and named it for himself and Sue Barton, his high-school sweetheart and now his wife. PSB stayed in St. Jacobs for about its first eight years.

The Ottawa connection. In 1973 or 1974 (sources differ) PSB's Beta II caught the attention of Dr. Floyd Toole at the National Research Council in Ottawa, and Barton has used the NRC's Ottawa facilities since 1974. PSB says every speaker it makes is still voiced in the NRC's anechoic chambers.

Lenbrook and Stratus. The Lenbrook Group of Pickering, Ontario bought PSB in the mid-1980s (PSB's own timeline says 1985), and PSB is now based in Pickering. The Stratus series began in the late 1980s, and Stereophile first reviewed the Stratus Gold in 1991.

Alpha, Image and beyond. The budget Alpha launched in 1991, and more than 50,000 pairs had sold by 2000. The Image series replaced the Century series in 1999, the Platinum flagship followed in 2002, then Synchrony in 2007 and Imagine in 2008. PSB marked its 50th anniversary in 2022 with the Passif 50.

Early models (1970s and 1980s): the Beta II, Avanté II, Passif II and Project B2, then the R series after the Lenbrook purchase.

Stratus (late 1980s to the 2000s): the upper line, including the Mini, Silver, Gold and Gold i. The Gold is a three-way with a 10" woofer.

Alpha (1991 to today): the entry line, including the Alpha A/V, Alpha B, Alpha B1 and later the Alpha P5. Our best-selling Alpha Intro LR and Alpha B come from this family.

Image (1999 to the 2010s): one step above Alpha. Our best-selling Image 8C centre and Image 4T towers come from this family.

Platinum (2002), Synchrony (2007) and Imagine (2008): the higher lines of the 2000s.

SubSeries and SubZero: PSB's powered subwoofers, such as the Alpha SubZero i we sell often.

Where it was made. Lines launched from about 2008 onward, such as Imagine and later Image and Alpha models, were made in China. Check the label before calling an older PSB "made in Canada"; spec sheets from the 1990s list only the Pickering address.

Amplifier load. The Stratus Gold and Gold i have a 4-ohm nominal impedance, and owners say Stratus models want an amplifier with plenty of current.

Image tweeters. On Image series speakers, check that every tweeter works and sounds as bright as its partner. A dim or dead tweeter is a frequent point of failure on that line. We sell a new Peerless 1" replacement tweeter that drops straight in (Image 1B, 2B, 4T, 5T, 8C, 10S and more) and is more robust than the original, and we can install it while you wait.

Drivers. Owners report occasional woofer failures on older towers. Listen to each driver on its own.

Surrounds. Many PSB woofers, such as the Platinum T8's, use rubber surrounds rather than foam, but press gently on any woofer surround to check it.

Everything we list is inspected, tested and serviced as required here, and comes with our warranty.
