HTM81 D4 High-end Center Channel Speaker
Small wonder that it’s such a powerful and whole-hearted performer, with both bass power and midrange extension that perfectly matches the quality of its illustrious stablemates. Available with an optional matching floor stand for the perfect installation.
Reverse Wrap Cabinet
Instead of a flat-fronted speaker with a curving back, Bowers & Wilkins' cabinets are formed from one continuous curve, held together with a spine of solid aluminum. Fewer joins make for a stiffer, more inert structure and a curved front means less baffling around the drive units. So sound dispersion is improved, and cabinet reflection is reduced.
Sometimes, making a big difference takes unconventional thinking. For decades, Bowers & Wilkins thought nothing could improve on the sound of their famous yellow Aramid Fibre midrange cones, but eventually, the Continuum cone technology changed their minds. Now, Bowers & Wilkins has turned their attention to another crucial element in a loudspeaker cone: the fabric spider. The all-new Biomimetic Suspension revolutionizes midrange cone performance by greatly reducing the unwanted air pressure and coloration that a conventional fabric spider can generate. The result? Midrange transparency you wouldn’t believe possible.
Thanks to its composite construction, the Continuum™ cone avoids the abrupt transitions in behavior that can impair the performance of a conventional drive unit. The result is a more open, neutral performance that delivers voices and instruments with precision and transparency.
Decoupled Midrange Assembly
Every 800 Series Diamond loudspeaker aside from the stand-mount 805 D4 has a dedicated midrange cone using four key Bowers & Wilkins technologies: the Continuum cone, FST™, Biomimetic Suspension and midrange decoupling, the latter ensuring minimal interference from the operation of the loudspeaker’s bass drivers.
Every stereo model in the new 800 Series Diamond range has a significantly upgraded cabinet design with an all-new aluminum top section for even greater stiffness. The same design also provides a perfect mounting point for all-new Leather by Connolly cabinet detailing, with luxurious black leather for dark cabinets and light grey for lighter finishes.
All stereo models in the new 800 Series Diamond range now use rear-mounted crossover designs mounted on stiff aluminum spines. This isolates the sensitive capacitors from the unwanted effects of air pressure within the enclosure and makes for a very effective heatsink to ensure optimum performance when in use.
