Compact and discreet, yet introducing technologies never before seen in any Bowers & Wilkins speaker, PM1 produces a sound so refined that everything else suddenly seems insignificant.


With a break-up frequency of 30kHz, our aluminium dome tweeters already push sound quality well above the upper limits of the audible range. But inspired by what we’ve learned about diamond, we wanted to see if we could do even better for the PM1. The result is an entirely new type of tweeter dome. By bracing the dome with a ring of filament-wound carbon fibre, we’ve raised the break-up frequency of aluminium to 40kHz.
