Offered is „CLS 1“ by Martin Logan as second-hand device from the category „Standing Speaker“ on audio-markt.de - the online market place for high-end. The advert with the number 2717246689 ends on 27.11.2026 at 08:59 o'clock.
At €1,000, this is a strong buy if the pair is genuinely complete and the panels are healthy; that’s well below the usual rough used range of about €1,500–€2,500 for decent examples, so it compares very favorably with buying a newer dynamic speaker at the same money. It’s not a steal in the sense of a bargain-basement fluke, but for a classic electrostatic with this reputation, it’s priced attractively.
What makes it worth chasing is the CLS’s big, spooky-transparent midrange and huge soundstage: vocals, strings, and small jazz ensembles can sound wonderfully alive, and this is one of those designs that still feels special decades on. The real buyer focus is panel condition, channel balance, and whether it has been properly stored and kept away from humidity; if those check out, €1,000 is the kind of price that makes sense for a serious enthusiast.

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.
