Reverse Wrap cabinet
Instead of a conventional loudspeaker box, our 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 for us 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 coloration 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 we do. We question, we examine, we understand and then we evolve. We use computer modelling to explore and reimagine every aspect of loudspeaker design. Learn more about all the technologies that combine to make 800 Series Diamond so special here.
