Celestion 100 Standmount Speakers (Mahogany Veneer) – Classic SL6 Evolution. They are fully working and sound excellent. One aluminium dome tweeter has an indentation (see photos). It still plays music cleanly, I have left this completely untouched to avoid damage.The Mahogany veneer has some age-related scuffs, and minor scratches Original cloth grilles are included and in good shape.

This is a buyer’s market at this level, and £250 looks ambitious against the local used spread: it sits well above the median £145 and even past the 75th percentile £198. That means it would need unusually strong condition, originality, or extras to fully justify the ask.
What still makes it interesting is that this is the kind of classic Celestion that can deliver a big, easygoing presentation with real vintage charm, so a clean, well-kept pair can still be worth chasing. If the drivers are original, surrounds and cabinets are healthy, and the sale includes grilles or stands, there’s some upside here — but at £250, I’d want those details to be excellent before calling it a buy.

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.
