Description

A pair of PSB 50 MkII two-way monitors in black ash, built in Canada.

What they are

Bigger than “bookshelf” suggests. These stand twenty-five inches tall and weigh thirty pounds each, with heavy internal bracing and a cabinet that does not talk back at you.

The eight-inch polypropylene woofer sits in a cast basket rather than a stamped frame. That is not a detail PSB had to spend money on at this price, and they spent it anyway. Above it, a one-inch textile dome handles the top end with the unforced quality fabric domes do well — detailed without ever turning bright or brittle.

What you get for all that is a speaker that plays considerably bigger than its footprint and goes genuinely low. Thirty-five hertz is real bass extension, and at 90 dB sensitivity it does not demand an expensive amplifier to get there. These suit a medium to large room and reward being given a little space from the wall behind them.

Made in Canada

PSB is the company Paul Barton built, and these were made in Canada. The voicing philosophy behind them — measure properly, then listen properly — is audible in speakers of this vintage, and it is why the name still carries weight with Canadian buyers who grew up on it. An eight-inch two-way with cast baskets is not a build anyone offers at this kind of money now.

The replaced woofer

One woofer on this pair has been replaced. The replacement is a genuine PSB driver, ordered direct from PSB in 2004 and supplied by them as the correct part for this exact model — not a generic substitute dropped into the hole. It carries PSB’s own service label, part M5212R/INT, and it matches its partner.

We would rather state that plainly than have anyone discover it. A factory part fitted twenty years ago is a repair done properly, not a compromise.

Condition

We have graded this pair Good, and we don’t hand that rating out casually. The reason for the grade is light marking on one cabinet in the area around the woofer. It is entirely hidden with the grilles in place and invisible in normal use, and a less strict grade would have been defensible. We would rather you find the speaker better than the description than the other way round.

Everything has been thoroughly inspected and tested to confirm full functionality.

A lot of speaker for the money, honestly graded, Canadian-built, and carrying a genuine PSB driver where it counts.

🔌 Speaker Cable, Built on Our Own Bench

The speaker terminals here are five-way binding posts, so they take banana plugs or spade lugs and you have the run of the options. We hand-build speaker cable here in any length you need — choose the gauge and the terminations on our Custom Speaker Cable Builder. If you would rather terminate cable you already own, we make our own gold-plated banana plugs and spade connectors as well. 👉

🦶 IsoAcoustics GAIA III — the Right Rating for These Towers

At 30 lb each, the PSB 50 MkII sits well inside the rating of IsoAcoustics GAIA III isolators — 70 lb per set of four — which decouple each cabinet from the floor. Ask us to confirm the thread fit to these cabinets before you order. On carpet, add GAIA Carpet Discs. We are an authorized IsoAcoustics dealer. 👉

PSB began in the summer of 1972 in St. Jacobs, Ontario, where Paul Barton and two high-school friends started building speakers. The name stands for Paul and Sue Barton. PSB says every speaker it makes is voiced in the National Research Council's anechoic chambers here in Ottawa. We carry PSB towers, bookshelf speakers, centre channels and subwoofers. We've had more than 440 PSB listings so far, covering nearly 90 different models, second only to our other big Canadian brand, Paradigm. Every used PSB here is inspected, tested and serviced as required, then photographed in-house and covered by our Bumper-to-Bumper Warranty and Perpetual Trade-Back Program. Don't see the model you want? Tell us on First Dibs and we'll email you when one arrives.

Our five best-selling PSB models so far: the Alpha Intro LR bookshelf speakers, the Image 8C centre, the Image 4T towers, the Alpha SubZero i subwoofer and the Alpha B bookshelf speakers.

The PSB story, 1972 to today

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.

Which PSB is which?

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.

Buying used PSB: what to check

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.
