PSB Image 10S Bipole Surround Speakers — Black | Canada

$395.00

Two driver modules per cabinet — a 25mm aluminium dome tweeter and a 133mm polypropylene woofer in each — angled rather than run out of phase, which widens the listening window without the comb filtering a true dipole introduces. Crossover at 2,500 Hz, 91 dB sensitivity into 6 ohms, 65 Hz to 23 kHz. Made in Canada, and a set of flush wall mounts comes with them.

Description

Made in Canada, the PSB Image 10S is a purpose-designed semi-bipole surround speaker from PSB’s highly regarded Image series — a four-driver, dual-module design built to deliver immersive, enveloping surround sound in both dedicated home theater rooms and everyday living spaces.

The 10S uses a semi-bipole configuration rather than a true dipole, and that distinction matters. Where a dipole uses out-of-phase drivers to create a deliberately diffuse, non-localizable sound field, PSB’s bipole approach angles the two driver modules to act more like a cohesive point source with a dramatically widened listening window. The result is surround performance that blends the ambient envelopment of a dipole with the dynamic precision of a direct-radiating speaker — capable of handling both the diffuse atmospherics of a film soundtrack and the directional demands of discrete surround effects without the comb filtering artefacts that straight dipoles can introduce. Sound & Vision praised the Image system for its “powerful, articulate, engaging sound” and the 10S’s unique contribution to that.

Each module carries a 25mm aluminium dome tweeter and a 133mm polypropylene woofer with rubber surround, for a combined four-driver array per speaker. The angled module geometry maintains flat on-axis response while delivering unusually consistent ±30° off-axis performance — a hallmark of PSB’s NRC-informed design process. At 91 dB sensitivity (93 dB in room) into a 6-ohm nominal load, the 10S is an easy drive for any AV receiver with adequate current delivery.

This unit has been thoroughly inspected and tested to confirm full functionality.

About brand

PSB at Radique

We service PSB, too. Bring us your own PSB speakers and subwoofers, including Image tweeter replacements for repair, servicing or restoration (speakers up to 80 lbs each), with a 90-day warranty on the work. See our Audio Service page

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.
