I have a set of the footers/spikes from a pair of Martin Logan CLS electrostatics I owned years ago. They are beautifully machined. The CLS manual states “The thread size for Martin Logan CLS spiked footers is 1/4" x 20. Martin Logan ETC spikes will fit any common 1/4" x 20 thread insert,”’
£30 for a MartinLogan CLS I B floorstanding speaker is an impossible bargain that signals a broken listing, scam, or a severe misunderstanding of the item, as typical used pairs command £1,200–£2,000 (roughly $1,500–$2,500) in the current market. No legitimate seller would offer these hybrid electrostatic-dynamic speakers for such a trivial sum; you should treat this as a non-buy until the seller clarifies whether the price applies to a single damaged panel, a non-functional unit, or if the listing is simply erroneous.
The CLS is legendary for its razor-sharp midrange detail and airy electrostatic transparency paired with dynamic bass, making it a top-tier choice for critical listening when intact. However, at £30, the only worthwhile angle is if you are an expert technician seeking a parts-only project, as replacing the aging electrostatic panels costs around £800 ($1,000) alone and the panels typically last only a decade. Unless the seller confirms the speakers are fully functional and the price is a typo, this is not a buying opportunity but a red flag.
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.
