PMC twenty5 23i Compact Floor Standing Speaker

The 23 has proved to be the most popular model in PMC’s twenty and twenty5 range of speakers, and the twenty5.23i  looks set to follow their success. Its discreet and elegant floor-standing form is perfect for filling medium-sized rooms with transparent, authentic dynamics and effortlessly extended bass, and it will blend unobtrusively into any room, whether your chosen décor is modern or traditional. As with all of the twenty5i range, the twenty5 23i will make the best of even affordable source electronics, and, coupled with high-end amplification, will truly excel.

Advanced Transmission Line Technology (ATL™)

The source of PMC’s natural, realistic sound is the Advanced Transmission Line (ATL™) bass-loading technology, professionally proven all around the world. ATL™ uses energy generated by the bass unit in a much more intelligent, efficient way than speaker designs based on ported or sealed boxes. In ATL™ loudspeakers, the highly braced cabinet is lined with a multitude of custom-designed acoustic materials that absorb all but the very lowest frequencies. These exit from a front-panel vent, extending the low-frequency response, and creating the impression of a far larger speaker with an extra, ultra-high quality bass unit. ATL™ improves more than just the bass response; because the low end is clean and clear, it doesn’t mask the rest of the music. Vocals, in particular, are beautifully projected and ultra-vivid. ATL™ loudspeakers offer another benefit. The ATL™ bass extension does not change with volume level — so even when listening quietly, the bass sounds balanced and well defined

Advanced driver design

PMC put over 25 years of experience into designing and manufacturing the bass driver for the twenty5 series. The twenty5i range features the same high-specification bass units, crafted to produce audio with the maximum possible drive, resolution and detail, and minimum colouration. The driver cone is made from a custom resin-bound, fine-weave glassfibre composite to ensure maximum rigidity and strength — conventional cones would simply crumple and deform when coupled to the ATL™ in the cabinet. And yet the driver is ultra-light, so it can respond instantly to changes in dynamics and also remains tonally neutral. With PMC’s ATL™ and Laminair™ technologies, these drivers allow you to hear your music, not the loudspeaker.

SONOMEX™ soft-dome tweeter

The new twenty5i high-frequency driver, a 19mm SONOMEX™ soft-dome design, was derived from the high-frequency unit on PMC’s premium fact speaker range; both were co-engineered with respected Norwegian driver manufacturers SEAS. The dome on the twenty5i range is mounted in the centre of a large roll surround, an arrangement which gives the effect of two drivers in one; it can produce the wide dispersion of a small-dome driver and the higher output of a larger driver. The newly designed ultra-rigid HF dispersion plate and grille enlarge the optimum listening position still further, meaning you can listen from a wide variety of positions in your room and still enjoy PMC’s consistent, ultra-detailed sound with razor-sharp imaging.

Sophisticated crossover design

The twenty5i models feature sophisticated crossovers with accurate filters mounted on military-grade fibre-glass boards, ensuring that only the ideal frequency range is precisely routed to the correct driver. Thick, pure copper tracks are used to connect the hand-selected crossover components to optimise signal delivery, and even the material of the crossover back plate has been carefully considered. The brushed stainless-steel back panel is also magnetically inert, preventing any adverse interaction with components.

Designed and built in the UK

PMC loudspeakers are designed and hand-built with care and attention by fastidious people at the PMC facility in the UK, where every single component is measured and graded. Every detail, from the individual elements on the crossover and in the drive units right up to the cabinet, is tested to ensure it meets their exacting standards for performance and reliability. This ensures each new model is a duplicate of the reference design.
