PM1 The PM1 is a luxury, compact loudspeaker; the latest in a long line of Bowers & Wilkins audiophile mini monitors. It offers an extremely high-quality audio performance, and features several technological innovations.
This includes the new Carbon Braced Tweeter. An aluminium dome is strategically stiffened with a wound ring of carbon fibre, pushing the breakup frequency to above 40kHz, providing a marked improvement in performance in the audible frequencies below 20kHz. The PM1 cabinet is also unlike anything previously constructed by Bowers & Wilkins. It combines the Matrix bracing system for greater rigidity, with a new moulded baffle and top plate for improved image localization.
The enclosure, crossover and terminals are all designed to achieve maximum synergy between all the components. The result is a loudspeaker that is expansive, with incredibly coherent staging aided by the new Carbon Braced Tweeter. Coupled with unprecedented levels of scale and authority for such a compact design.
