DIY KEF CS7 inspired Floorstanding Loudspeakers Here I have a DIY pair of customised KEF CS7 floorstanding speakers made by me. All drivers are in excellent condition. Think KEF Concertos on steroids, with better bass from correct CS7 size sealed enclosures. Crossovers are modified DN12 with added volume pot for tweeter to adjust to your liking. Sound better than Kef Concertos, and you don't need stands. No front grille design. Enclosures in great cosmetic condition. Sizes: 890H x 340W x 370D on castors. Pickup only from Keysborough 3173. Cash on pickup only. Condition: Very Good Payment Metho
A A$550 asking price for a KEF CS7-inspired pair is strong value if this is the real thing in decent condition: a comparable new floorstander from KEF’s C-series sits well above that, so this is comfortably in used-buy territory rather than “pay near-new” territory. Against the obvious alternative at this price point—entry-level new speakers—this should be the more refined, more substantial listen if the drivers and cabinets are healthy.
KEF’s house sound is typically neutral, open, and wide-dispersion, which makes these appealing for both music and TV duty. For a used pair, the real upside is getting that KEF clarity and imaging at a sensible outlay; if the cabinets are clean, grilles are intact, and there’s no driver fatigue or foam/surround damage, this reads as a proper enthusiast buy rather than a gamble.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
KEF traces its roots to 1961, when British engineer Raymond Cooke founded the company in a modest Nissen hut on the grounds of the Kent Engineering and Foundry in Maidstone, England. A former BBC engineer and Wharfedale veteran, Cooke was driven by a passion for music and a commitment to technological innovation, aiming to reproduce sound as faithfully as the original performance. From its inception, KEF pioneered materials like foil-stiffened polystyrene diaphragms and Melinex tweeters in its debut K1 loudspeaker, setting a benchmark for engineering precision that propelled the brand to early acclaim.
KEF has long specialized in loudspeakers, establishing itself as a leader with iconic innovations such as the Uni-Q coaxial driver and computer-aided design techniques that revolutionized driver and enclosure development. While drive units supplied to other manufacturers fueled its growth, the brand's core output remains high-fidelity speakers across categories like floorstanders, bookshelves, and home theater systems, including early THX-approved setups. Active wireless models and reference-grade series extend its portfolio, though it eschews amplifiers, turntables, DACs, headphones, or cables.
Renowned for its science-driven heritage, KEF occupies a premium position in the hi-fi market, blending accessible high-end performance with cutting-edge technology. Collectors prize vintage BBC monitors and Bextrene-driver classics, while modern buyers seek its precise, natural soundstaging. Decades of awards affirm KEF's status as a respected innovator, appealing to discerning audiophiles who value engineering over hype.
