They have been used in our Norwich showroom for demonstration purposes only, and are in excellent condition. Both speakers are supplied complete with all original accessories and packaging. Shipping costs vary depending on location — please contact us before purchasing to discuss delivery, and we are happy to talk through any part-exchange or trade-in you may have in mind.\u003c\/p\u003e\n\u003ch2\u003eThe Diamond Dome Tweeter\u003c\/h2\u003e\n\u003cp\u003eThe 805 D4's tweeter is machined from synthetic diamond — the hardest known material — allowing it to operate far beyond the limits of conventional metal or fabric domes. The result is vanishingly low distortion at the top of the frequency range, where lesser tweeters compress and colour the sound. Bowers \u0026amp; Wilkins mount this driver in a decoupled Tweeter-on-Top housing, isolating it from the cabinet and allowing it to operate with extraordinary precision — a design first seen on the flagship 800 D4 and now the cornerstone of the entire 800 Series Diamond range.\u003c\/p\u003e\n\u003ch2\u003eContinuum Cone Midrange\u003c\/h2\u003e\n\u003cp\u003eThe 805 D4 uses Bowers \u0026amp; Wilkins' Continuum woven cone — a proprietary material developed over years of research to eliminate the colouration and breakup modes that afflict conventional paper and Kevlar drivers. The Continuum cone reproduces midrange frequencies with a purity and transparency that sets a new standard for a speaker of this size, resolving low-level detail and subtle tonal nuance that previously unsurpassed designs could not match.\u003c\/p\u003e\n\u003ch2\u003eBiomimetic Suspension\u003c\/h2\u003e\n\u003cp\u003eBowers \u0026amp; Wilkins' Biomimetic Suspension replaces the conventional foam surround spider with an open lattice structure inspired by natural forms — dramatically reducing air flow resistance and the non-linear behaviour that blurs transient detail. The effect on timing and dynamic accuracy is immediate and unmistakable: the 805 D4 tracks the leading edge of notes with a precision that transforms the listening experience, delivering the PRAT and rhythmic coherence that separates truly great loudspeakers from merely excellent ones.\u003c\/p\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eDrive units\u003c\/th\u003e\n\u003ctd\u003e1× 25mm diamond dome tweeter, 1× 150mm Continuum cone midrange\/bass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFrequency response\u003c\/th\u003e\n\u003ctd\u003e42Hz – 35kHz (–6dB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSensitivity\u003c\/th\u003e\n\u003ctd\u003e88dB spl (2.83V, 1m)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNominal impedance\u003c\/th\u003e\n\u003ctd\u003e8 ohms (minimum 3.1 ohms)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRecommended amplifier power\u003c\/th\u003e\n\u003ctd\u003e30W – 120W into 8 ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinish\u003c\/th\u003e\n\u003ctd\u003eGloss Black\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCondition\u003c\/th\u003e\n\u003ctd\u003eEx-demonstration, excellent condition, all original accessories and packaging included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eWho Is It For?\u003c\/h2\u003e\n\u003cp\u003eThe 805 D4 is the standmount of choice for listeners who demand the full resolution and dynamic authority of the 800 Series Diamond bloodline in a compact form. It rewards high-quality amplification — partnered with a capable integrated or power amplifier, it will outperform standmounters costing considerably more at full retail. This ex-demonstration opportunity makes one of the world's finest standmount loudspeakers available at a price that would be difficult to justify ignoring.\u003c\/p\u003e\n\u003ch2\u003eBuying from Martins Hi-Fi\u003c\/h2\u003e\n\u003cp\u003eMartins Hi-Fi has been in Norwich since 1968.
