Ik verkoop mijn in zeer nette en goede staat celestion sl6 monitors inclusief de stands. De sl6 designed by allen bothroyd late 80s heeft een zeer gedetailleerd natuurlijk en neutraal geluid en pracht
Celestion’s SL6Si sits in that classic compact British-monitor lane: respected, compact, and often bought for its honest midrange and musical balance rather than brute force. At €325, this is above the €318 75th percentile, so it reads ambitious rather than a bargain against your recent EUR comps; it is not wildly out of line, but it is priced at the upper end of the current used market.
That said, a clean pair can still be worth paying for if the cabinets, drivers, and crossovers are original and healthy, since these are the sorts of speakers people keep for their tonal coherence and easy placement. The upside here is mainly quality and scarcity in good cosmetic condition, so if the listing is genuinely tidy and complete, it can make sense for a buyer who wants the model rather than the cheapest route into vintage Celestion sound.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Celestion traces its origins to 1924 in Hampton Wick, on the outskirts of London, where Cyril French and his brothers founded the Electrical Manufacturing and Plating Company. Tasked with refining Eric Mackintosh's early cone loudspeaker invention—a bamboo-reinforced "free-vibrating edge" design—they patented it that year and named their breakthrough product the Celestion. By 1928, the firm had incorporated as Celestion Ltd., adopting the motto "The Very Soul of Music" amid rapid expansion into radiogram speakers and cabinets, before acquisitions by British Rola in 1946 and later Truvox reshaped its trajectory.
The brand specializes in loudspeakers, with a legacy rooted in innovative drivers for radios, hi-fi systems, and professional audio. Iconic models like the G12 series, first developed in 1936 and toughened into the 1959 T530 Alnico Blue—the world's inaugural guitar amp speaker—cemented its prowess. Today, Celestion produces pro audio loudspeakers, guitar cabinets, and replacement drivers, emphasizing precision engineering for sound reinforcement and instrument amplification, all manufactured under ISO standards within the Gold Peak group.
Celestion commands a revered position as a vintage-inspired leader in the guitar and pro audio markets, prized by musicians and engineers for its punchy, articulate tone that defined rock legends from the 1960s onward. Neither purely high-end boutique nor mid-tier commodity, it blends heritage craftsmanship with reliable performance, appealing to discerning hi-fi buyers and tone chasers who value century-tested innovation over fleeting trends.
