Description Bowers & Wilkins HTM82 D4 Centre Speaker The Bowers & Wilkins HTM82 D4 Centre Speaker may be their most compact centre-channel speaker, but it shares the design DNA of its larger siblings, including the Reverse Wrap cabinet and Matrix™ bracing. The combination of the two technologies ensures a quieter, more acoustically efficient and better-sounding speaker than ever.

Reverse Wrap cabinet Instead of a conventional loudspeaker box, the cabinets are made from a continuous curved section of wood, with the drive units mounted at the heart of the curvature. This stiffer, more inert structure resists mechanical resonances far better and also ensures better dispersion of sound. Continuum™ cone midrange Introduced as a huge evolutionary change in 2015, the Continuum cone midrange drive has swiftly become a fundamental element in every Bowers & Wilkins loudspeaker. With exceptionally low noise, it ensures outstanding resolution without colouration or masking of detail. Decoupled midrange assembly HTM82 D4 has a dedicated midrange cone using three key Bowers & Wilkins technologies: the Continuum cone, Biomimetic Suspension and midrange decoupling, the latter ensuring minimal interference from the operation of the loudspeaker’s bass drivers. The result is outstanding clarity. The science of sound Innovation is at the heart of everything they do. They question, examine, understand and then evolve. They use computer modelling to explore and reimagine every aspect of loudspeaker design.
