Magnepan SMGa Floorstanding Loudspeakers Looking for a pair of high-fidelity, planar magnetic speakers that deliver an immersive and natural soundstage? I’m selling a pair of Magnaplanar MagnaPan SMGa speakers in good condition, perfect for audiophiles and vintage speaker collectors. Specifications: • Type: Planar Magnetic Loudspeaker • Impedance: 4 Ohms • Frequency Response: 50 Hz – 26 kHz • Crossover Frequency: 1.8 kHz • Recommended Amplifier Power: 40W – 200W RMS per channel • Efficiency: ~86 dB (1W/1m) • Speaker Dimensions: Approx. 48” (H) x 18” (W) x 2” (D) • Weight: ~25 lbs each • Conn
This is a seller’s market only in the sense that the ask is a touch above the middle, but at A$1,200 it’s still basically a fair, near-median listing against your recent comparable set: A$1,117 median, A$809 at the 25th percentile, and A$1,167 at the 75th percentile. It’s not a bargain, but it’s also not ambitious; it sits just over the upper quartile and close enough to the median to read as reasonably priced for a patient buyer.
The appeal here is the classic Magnepan thing: big, open, boxless sound with a naturally spacious midrange and a presentation that can make vocals and acoustic instruments feel uncannily real. If the panels are healthy and the socks/frame are tidy, this is the kind of speaker that can outperform many newer box speakers for imaging and transparency, especially with the right amp and room. At this price, I’d just verify condition carefully—uniform output, no torn/sagging panels, and no age-related quirks—because with planars, condition matters more than cosmetics.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Founded in 1969 in White Bear Lake, Minnesota, by engineer Jim Winey, Magnepan emerged from his dissatisfaction with electrostatic speakers during his time at 3M. Seeking a superior alternative, Winey invented the Magneplanar—a thin-film magnetic driver that rivaled electrostats without their limitations. Bootstrapped with funds from friends and family, the family-owned company has remained American-made, now led by Winey's son Mark from a 50,000-square-foot facility, upholding over five decades of planar innovation.
Magnepan specializes exclusively in planar magnetic loudspeakers, from compact Mini Maggies to towering flagships like the 3.7i. These full-range or hybrid panels eschew traditional cones for quasi-ribbon and true-ribbon drivers, delivering expansive soundstages and lifelike transients. The lineup avoids amplifiers, turntables, DACs, headphones, or cables, focusing solely on speakers that demand high-current amplification to thrive.
Positioned as a high-end niche leader, Magnepan commands reverence among audiophiles for neutral voicing, room-filling dispersion, and value that outpaces competitors dollar-for-dollar. Handcrafted in the USA with domestic parts—"Made in America. Sold in China"—its panels offer unmatched transparency at premium prices, cementing a legacy as the pinnacle of planar magnetic reproduction for discerning listeners worldwide.
