PMC Twenty 5 23 Speakers

The most elegant model in the range, the twenty5 23 takes the speed, transparency and sophistication of the twenty5 23 and adds greater bass extension and power. And yet its slim-line form doesn’t mean it can’t move you.

No matter what type of music you love, the twenty5 23 will let you absorb the quietest and most dramatic moments without missing a beat, and its realism with vocals puts you in the best seat in the house. The first and overwhelming impression of the twenty 23's is an open, engaging and communicative loudspeaker. The sound is vivid and dynamic and delivered with authoritative bass.


The twenty5 series is the culmination of a quarter of a century of research, obsessive design and craft to produce the very finest loudspeakers for home listening. Every element in the design has been considered in order to create finely tuned, transparent speakers capable of revealing music’s subtlest shades and deeply emotional details.


With the launch of the twenty5 series, audio performance has been taken to the next level with the addition of the Laminair aerodynamic vent. Head of Design Oliver Thomas applied aerodynamic principles he had discovered in his previous employment in Formula One to ATL, creating an even smoother, laminar airflow at the exit from the transmission line. ATL designs involve air moving at high speeds and under pressure, and Oliver showed that reducing turbulence and drag at the ATL vent reduces resistance, increases efficiency, eliminates air noise and provides bass with supreme timing and the ultimate dynamic range.


heightened level of performance produced by the twenty5 series puts huge demands on the construction of the bass and midbass drivers, so a far stiffer cone is necessary to produce maximum resolution and musical power, and minimum colouration. PMC has developed g-weave, a resin-bound, fine-weave glass fibre and pulp hybrid cone to achieve this goal. The g-weave cone is far stronger than paper and doesn’t impart any character, ensuring you hear more music and less loudspeaker. The trio of bespoke drivers is extremely powerful, with exceptional travel. Teamed with the ATL and Laminair vent, they bring you closer than ever before to the live music experience without leaving your home.


For the twenty5 series PMC continues to use tweeters coengineered with Norwegian electro-acoustic craftsmen SEAS, one of the world’s finest purveyors of drive-unit technology. The precision 27mm soft-dome driver is made from Sonolex, a highly sophisticated material that ensures an exceedingly smooth natural response and guarantees perfect pair matching. The perforated polished grille is computer modelled for optimum dispersion and razor-sharp imaging, and creates an intense three-dimensional image that covers a vast listening area.


PMC is renowned and respected in the ultra-critical studio and audiophile markets for its soft-dome mid-range drive units. On the twenty5 series, this produces vocals that are not merely transparent, but relay all the emotional character in the artist’s voice. Like the tweeter, the mid-range driver has enough power to fill a huge space, with an ideal-sounding, balanced soundstage.


For a wide sweet spot and natural sound, a loudspeaker must have a minimum of separate low and high-frequency drivers. A third element is also required: the crossover. This is a fundamental part of the system; it should divide the audio signal into frequency bands ideal for each drive unit. The calibre of a crossover’s design and construction has a powerful influence on the overall sound quality of the loudspeaker.

For the twenty5 series, we have employed computer simulations and an extensive programme of test and measurement to design highly sophisticated crossovers that divide the signal with utmost precision. The foundation for the crossover is its military-grade, glass-fibre board with the widest, thickest possible conductive copper tracks. These ensure that resistance is kept as low as possible and power delivery to the drive units is maximised.

Each component has been chosen through extensive listening tests, and its position on the board has been optimised to prevent unwanted interactions. We go to the extent of recording, matching and soldering components by hand to guarantee the best possible sound quality and reliability. This attention to even the smallest detail can pay huge dividends; even the material of the crossover back plate has been considered. The mirror-finish, stainless-steel back panel is magnetically inert, preventing any adverse interaction with components.


Our holistic design philosophy means we consider every element of the loudspeaker and the effect on its performance.


Creating the ideal connection are the bespoke twenty5 series binding posts, machined from pure copper and plated with matte rhodium for the last word in conductivity. They accept all popular terminations and are directly coupled to the crossover board to keep the signal path as short as possible. SpikeS The custom-made, one-piece stainless-steel spikes thread into the plinth bar for a sure-footed, straightforward set up.


The elegant, slim-line grilles are fixed to the cabinet with concealed magnets, leaving the loudspeaker’s front baffle clean and unblemished by unsightly fastenings. We even go to the extent of weaving our own acoustically transparent cloth and modifying the shape of the grilles so as not to adversely affect the sound quality when they are in use.
