Castle Richmond 3i floor standing speakers. Solid Oak. Very good condition. Hardly use yet worn in nicely. Very solid sound. 23kg units each. Have own stand base plates with spikes. Typical Castle sound. Very clear, balanced, excellent sound stage. Will handle a lot of power and sound considerably bigger than they are. Buyer pays postage. Questions welcomed.
£499 is above the median of £331 and well above the 75th percentile of £1,316? Wait—using your anchor, it is actually below the 75th percentile but above the median, so this reads as a slightly ambitious but still plausible ask rather than a bargain.
This line is well regarded for its straightforward, room-friendly balance and easy placement, so a clean example can be a sensible buy if you want a classic British standmount with decent refinement and no fuss. At this level, the key value is condition: check for intact drivers, original grilles, and any signs of foam/suspension or cabinet wear, because the model’s appeal is strongest when it’s complete and obviously cared for.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Castle Acoustics, a revered British loudspeaker brand, traces its origins to September 3, 1973, when it was founded in the North Yorkshire market town of Skipton by William "Bill" Escott and John Collinson. Both veterans of Wharfedale—and Collinson also of Quad—these engineers established the company in an old woollen mill, drawing its name and logo from the historic Skipton Castle. From the outset, Castle emphasized complete in-house production, crafting drive units, electronic components, and hand-veneered wooden cabinets under one roof, setting it apart in the 1970s hi-fi landscape.
The brand has steadfastly focused on high-fidelity loudspeakers, eschewing diversification into amplifiers, turntables, DACs, headphones, or cables. Iconic models like the Howard, Harlech, Durham, Pembroke, and later Knight series exemplify its commitment to premium wood-veneered enclosures, woven carbon-fiber bass drivers, and cutting-edge acoustic engineering. Acquired by the International Audio Group in 2007, Castle has expanded into home cinema while preserving its two-channel heritage.
Positioned as a high-end boutique manufacturer, Castle commands respect among discerning hi-fi enthusiasts for its "no compromise" sonic performance, furniture-grade craftsmanship, and timeless musicality. Award-winning designs, such as the Knight series lauded by Hi-Fi Choice and Hi-Fi World, underscore its enduring appeal in the premium market, blending British tradition with modern innovation.
