PMC’s first ever product, the BB5, was installed at the BBC’s Maida Vale studios, London, in the early 1990s and set such high standards for reference monitoring and sonic neutrality that they are still in use over a quarter of a century later. In what is the most significant PMC product launch since that time, PMC is using Festival of Sound to  introduce the new flagship of the fact loudspeaker range — fenestria – to UK audiophiles.

A three-way, ultra-high-resolution passive twin ATL™ loudspeaker, fenestria incorporates all-new, tailor-made drivers, twin Laminair™ vents for improved aerodynamic ATL airflow, plus a newly designed cabinet that houses the treble and mid-range units in an innovative and elegant reflection-free module. The result is at once aesthetically beautiful and highly engineered, conveying the emotion of a musical performance with more subtlety and refinement than any other loudspeaker. Much of fenestria’s five-year design process has focussed on removing the unwanted distortion and colouration introduced by the loudspeaker itself, so that the listener hears nothing but music. For this reason, PMC refer to it as “the loudspeaker you’ll never hear.”

“fenestria is the perfect example of our holistic design approach,” explains Peter Thomas, PMC’s owner and chief designer. “Our aim was to make the best passive loudspeaker we could, with an open mind when it came to technologies and materials. We looked at all options to achieve the purest, most transparent sound, and fenestria was the result.”

PMC’s approach to loudspeaker design has been long admired and is the reason why its speakers are the tools of choice for many of the world’s leading recording studios, movie production companies, composers, musicians and engineers. With fenestria, the key design principle has been the elimination from the drive units and cabinets of all unwanted vibrations. These reduce the clarity, precision and neutrality of the speakers, and introduce colouration that detracts from the musical experience. As the loudspeaker evolved, every element – drive units, cabinet, transmission line, crossover – was subjected to vibration analysis using sensitive accelerometers, and the results of this analysis directly influenced the final design.

Available in White silk, Rich walnut, Graphite and Tiger ebony finishes, fenestria retails for £45,000 and can be experienced in the Mouton Cadet Suite on the 2nd Floor of the show, between 28-30 September.
