Engineered without compromise, it brings the full weight of B\u0026amp;W's most advanced loudspeaker technologies to bear on the centre channel, where the majority of a film's dialogue, detail and drama is anchored.\u003c\/p\u003e\n\n\u003cp\u003eMartin's Hi-Fi is the second oldest Bowers \u0026amp; Wilkins dealer in the world, and the HTM81 D5 is a product we are particularly well placed to demonstrate and advise on.\u003c\/p\u003e\n\n\u003ch2\u003eDiamond Dome Tweeter \u0026amp; Solid Body Tweeter-on-Top\u003c\/h2\u003e\n\u003cp\u003eThe HTM81 D5 carries B\u0026amp;W's Diamond dome tweeter — machined from single-crystal diamond, the hardest material available for this application — mounted in a Solid Body Tweeter-on-Top housing that decouples it entirely from the cabinet. Diamond is so stiff that its first breakup mode sits far beyond the audible range, meaning the tweeter operates in pure pistonic motion across every frequency it handles. The result is high-frequency reproduction of extraordinary clarity and composure, free from the colouration that plagues conventional dome materials.\u003c\/p\u003e\n\n\u003ch2\u003eContinuum Cone FST Midrange\u003c\/h2\u003e\n\u003cp\u003eThe midrange driver uses B\u0026amp;W's Continuum cone in an FST (Fixed Suspension Transducer) configuration, which eliminates the conventional surround and its associated resonances. Continuum is a woven material developed specifically by Bowers \u0026amp; Wilkins to combine the self-damping properties needed for low colouration with the stiffness required for accurate pistonic motion. Voices — the HTM81 D5's primary responsibility — are reproduced with a presence and intelligibility that makes the centre channel's role in a serious home theatre system immediately apparent.\u003c\/p\u003e\n\n\u003ch2\u003eAerofoil Bass Cones\u003c\/h2\u003e\n\u003cp\u003eTwin 200mm Aerofoil bass drivers handle the low frequencies. The Aerofoil cone has a profile that varies in thickness from edge to centre — stiff where stiffness is needed, lightweight where mass must be minimised — giving it a combination of low distortion and genuine low-frequency authority. Supported by a Flowport reflex loading and Anti-Resonance plug, the bass output is clean, controlled and capable of handling demanding cinematic material without strain.\u003c\/p\u003e\n\n\u003ch2\u003eMatrix Cabinet Construction\u003c\/h2\u003e\n\u003cp\u003eThe HTM81 D5's cabinet is braced internally with B\u0026amp;W's Matrix structure — a lattice of internal panels that dramatically increases rigidity without adding excessive mass. Biomimetic Suspension further reduces driver resonance. The result is a cabinet that stays inert under drive, so what you hear is the loudspeaker, not the box.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eConfiguration\u003c\/th\u003e\n\u003ctd\u003e3-way vented-box system\u003c\/td\u003e\n\u003c\/tr\u003e\n\n\n\n\u003ctr\u003e\n\u003cth\u003eFrequency range (-6dB)\u003c\/th\u003e\n\u003ctd\u003e20Hz to 35kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFrequency response (±3dB)\u003c\/th\u003e\n\u003ctd\u003e28Hz to 28kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSensitivity\u003c\/th\u003e\n\u003ctd\u003e90dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNominal impedance\u003c\/th\u003e\n\u003ctd\u003e8Ω (minimum 3.0Ω)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRecommended amplifier power\u003c\/th\u003e\n\u003ctd\u003e50W – 1000W into 8Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax recommended cable impedance\u003c\/th\u003e\n\u003ctd\u003e0.1Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeight\u003c\/th\u003e\n\u003ctd\u003e334mm (including tweeter)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWidth\u003c\/th\u003e\n\u003ctd\u003e846mm (cabinet only)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDepth\u003c\/th\u003e\n\u003ctd\u003e363mm (including grille and terminals)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNet weight\u003c\/th\u003e\n\u003ctd\u003e33.4kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFinishes\u003c\/th\u003e\n\u003ctd\u003eStealth Black, Warm White, Dark Walnut\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho Is It For?\u003c\/h2\u003e\n\u003cp\u003eThe HTM81 D5 is for the serious home theatre builder — someone who already owns or is planning a system around the Bowers \u0026amp; Wilkins 801 D5 or 802 D5 and refuses to let the centre channel be the weak link. It is not a casual purchase — at this level, the HTM81 D5 demands a properly configured surround processor and amplification to match. But for those building without compromise, there is no better centre speaker in the 800 Series range.\u003c\/p\u003e\n\n\u003ch2\u003eBuying from Martins Hi-Fi\u003c\/h2\u003e\n\u003cp\u003eMartins Hi-Fi has been in Norwich since 1968.
