Notable because Motion-series Monitors usually punch above their size, but this one is priced right on the money. At A$1,500, it sits essentially at the A$1,499 median and right between the A$1,497 and A$1,501 spread, so this is a fair ask rather than a bargain or stretch.
What makes it worth a look is the usual MartinLogan blend of clean midrange, lively treble detail, and a compact cabinet that suits serious near- to mid-field listening. If the pair is cosmetically tidy and complete, the upside is straightforward: a well-regarded bookshelf speaker at a sane market price. With no condition info, I’d still verify driver health, binding posts, grille fit, and any signs of hard use before committing.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
MartinLogan emerged in the late 1970s from Lawrence, Kansas, when Gayle Martin Sanders and Ron Logan Sutherland, sharing a passion for electrostatic loudspeakers, united their engineering and design expertise. The duo, whose middle names inspired the brand, unveiled their breakthrough at the 1983 CES with the Monolith—the world's first practical hybrid electrostatic speaker, blending a curved panel for mids and highs with a dynamic woofer for bass. This American innovation addressed longstanding electrostatic limitations like fragility and poor low-end response, propelling the company from a high-end audio store collaboration to a dedicated manufacturing powerhouse.
The brand specializes in electrostatic and hybrid speakers, from flagship floorstanders like the CLX and Summit X to more accessible Motion Series designs, alongside complementary powered subwoofers and select electronics. Their proprietary thin-film transducers, advanced panel assembly, and room-optimized engineering define a lineup that prioritizes transparency and precision over conventional dynamic drivers, eschewing amplifiers, turntables, DACs, headphones, or cables.
Positioned firmly in the high-end market, MartinLogan commands respect among discerning audiophiles for its unwavering commitment to electrostatic purity, delivering ethereal soundstaging and timbral accuracy that make cabinets vanish. Now part of the PML group alongside Paradigm and Anthem, it blends Kansas heritage with rigorous innovation, appealing to buyers seeking reference-level realism in home audio and theater systems.
