At USD$180 local pickup, you're looking at a solid deal. Used M-590i pairs typically fetch USD$400–USD$550 on the secondary market, so this is well below going rates—assuming the speakers are genuinely functional and cosmetically acceptable. Local pickup eliminates shipping costs that often run USD$150+, which sweetens the value further. The catch: verify they're the correct model first, since spec sheets vary between the 590 and 590i.
Before you commit, listen to them if possible—bipolar speakers are finicky about room placement and can sound diffuse or recessed if positioned carelessly. Check that both front and rear drivers fire cleanly (no rattles, no dead tweeters), and confirm the grilles and binding posts are intact. These are older designs, so ask about any service history or reconing work. If they've been sitting unused for years, the surrounds may have aged; that's a potential repair cost down the line.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Mirage is a Canadian speaker manufacturer with roots tracing to 1977, when a group of audiophiles founded the company with a singular mission: to create speakers delivering immersive, omnidirectional sound that would make listeners forget they were hearing reproduced audio rather than a live performance. The brand gained prominence through pioneering designs, most notably launching the world's first bipolar speaker, the M-1, which achieved approximately 360-degree sound diffusion throughout a listening room. Famed loudspeaker designer Kevin Voecks created the original Mirage designs, establishing the company's technical credibility from inception.
Throughout the 1980s and beyond, Mirage built its reputation on high-quality, affordably priced two-channel loudspeakers that earned consistent praise in audiophile publications. The company's early success was constrained only by manufacturing capacity, as demand frequently outpaced production. Mirage later expanded its portfolio to include more ambitious designs, including speakers featuring pure titanium hybrid tweeters, cementing its position as an innovator in speaker engineering rather than a manufacturer of ancillary components like amplifiers, DACs, or cables.
Mirage occupies the upper-mid to high-end segment of the speaker market, though its trajectory has been complicated by corporate ownership. Audio Products International, which owned Mirage, was acquired by Klipsch Group in 2006, after which the brand's market presence diminished significantly. However, the Mirage name remains synonymous with 360-degree immersive sound design and continues to represent a distinctive chapter in Canadian audio heritage, particularly among vintage and collector-focused enthusiasts who value its omnipolar design philosophy.
