This is a respected, purpose-built partner for the Quad ESL-63, and on the used market it usually isn’t a bargain-bin piece. At €1,200, the asking price looks fair to slightly strong rather than cheap, especially since seen examples for the pair and matching hardware have often sat around the mid-€1,000s to low-€2,000s depending on completeness and condition.
What makes it worthwhile is the integration: it was designed to work with the ESL-63 as both bass support and stand, so the payoff is coherence and proper panel height, not just extra low end. If the cabinet, drivers, and matching crossover/stands are all present and tidy, this is a serious enthusiast buy. The only real caveat is to confirm completeness and working condition, because missing matching pieces or tired electronics can turn a fair price into a repair project.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Gradient is a Finnish hi-fi brand founded in 1984 by Jorma Salmi, who had earlier worked in acoustics and electronics at Lohja Corporation Electronics and Nokia-related roles. The company’s identity has been built around loudspeaker engineering from the start, rather than broad consumer-electronics production.
Gradient is best known for loudspeakers and related speaker electronics, especially designs aimed at performing well in ordinary living rooms. Its lineup has included floorstanding and open-baffle speakers, and more recently products such as an active crossover/power amplifier have appeared, but speakers remain the core of the brand.
In the market, Gradient sits as a niche, high-end specialist rather than a mass-market audio name. Its reputation is strongest among serious audiophiles who value unconventional engineering and room-friendly design, and it has long been associated with Finnish hi-fi craftsmanship and a distinctly technical approach to sound.
