Some minor cosmetic wear, amazing sound.PSB Subsonic III Subwoofer, 200C Center, Amazing Alpha Pair -Home Theatre BundleThe PSB Subsonic III Subwoofer, 200C Center, and Amazing Alpha Pair combine to create a high-end home theatre bundle. These rectangular-shaped speakers, in sleek black, offer wired connectivity and are perfect for creating a home audio system. With its impressive PSB brand and premium features, this bundle delivers exceptional sound quality for an immersive listening experience.
At US$499, this PSB Subsonic III subwoofer sits comfortably below the 75th percentile of US$561 but above the median of US$331 for recent comparable listings, making it a fair, not bargain, price in the current used market. While new PSB subs like the SubSonic 5i launched around US$499, this older III model is well into its depreciation curve, so paying near original-new cost would be ambitious; however, US$499 is reasonable for a bundle that includes a 200C center speaker and Alpha pair, not just the sub alone.
The Subsonic III is a respected, self-powered design with a 10-inch polypropylene cone and 150W Class H amplifier, delivering solid 30–150Hz response that integrates cleanly in home theater setups. What makes this listing worthwhile is the full home-theater bundle: you’re getting a capable sub plus matching center and stereo speakers, which alone would typically push the total ask well over US$700 if bought separately. With no condition flags noted and original-owner appeal likely, this is a genuine buying opportunity for a complete, well-regarded PSB theater system at a fair aggregate price.

PSB Speakers traces its roots to 1972 in St. Jacobs, Ontario, Canada, where classically trained violinist and self-taught acoustics engineer Paul Barton launched the company with two school friends, pooling savings for a modest factory. Named after Paul and his high-school sweetheart Sue Barton—who later became his wife—the brand embodied Barton's early passion for hi-fi, honed through part-time work building speaker kits at a local shop and studies at the University of Waterloo. A pivotal collaboration with National Research Council psychoacoustician Dr. Floyd Toole in 1974 established PSB's rigorous testing in anechoic chambers and double-blind listening rooms, shaping its signature "Canadian Sound" of truthful, natural reproduction.
The company focuses squarely on loudspeakers, spanning entry-level Alpha models to high-end Platinum series, alongside home theater systems, in-ceiling CustomSound options, and expansions into headphones, portable Bluetooth speakers, and subwoofers. Acquired by the Lenbrook Group in 1985—which also owns NAD Electronics—PSB gained global distribution, now reaching over 70 countries while maintaining Barton as chief designer. This heritage of psychoacoustics research ensures products prioritize flat frequency response and musical accuracy over hype.
PSB holds a strong mid-to-high-end position among discerning audiophiles, revered for value-driven performance that rivals pricier rivals without gimmicks. Its scientific foundation and "true-to-nature" ethos earn consistent praise, cementing a reputation as a Canadian benchmark in a crowded market, distributed through premium dealers worldwide.
