PSB Image 10S Bipole Surround Speakers — Black | Canada

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.
