The PMC Twenty5 23i - In the previous Twenty5 series, the 23 was easily proven to be one of the most popular models in the series, now the newer 23i is looking to fit in that same success bracket and without a doubt, we firmly believe that it would be the case. What sets it apart is its discreet yet elegant floor-standing form which is more than ideal for filling any medium-sized room with nothing but transparent, authentic dynamics and effortlessly extended bass. When it comes to floorstanding speakers, you need to take size into consideration, luckily these speakers blend unobtrusively into any room, whether your preference is modern or traditional. As a standard rule of the Twenty5 series, it will make the best of even affordable source electronics but if you pair this with high-end amplification, you're going to be set for one amazing experience.

The Twenty5 23i uses PMC's ATL (Advanced Transmission Line) technology, to get some context on what this is, it's a technology that uses sophisticated cabinet construction, proprietary drive units, and patented absorption materials and techniques. The benefits you get from this are rather substantial compared to the relatively simple sealed and ported designs currently available elsewhere.

Cabinets

Creating the perfect cabinet, one that pleases both the eye and the ear, requires a partnership forged from cutting-edge, computer-controlled machining and an intimate knowledge of traditional craftsmanship and materials.

Structural integrity and accuracy are the most crucial elements when making any loudspeaker enclosure, and with PMC’s holistic design approach every element has been considered to enhance performance. Forming both the cabinet and housing the sophisticated ATL™(Advanced Transmission Line) are precision-machined panels of highly specified HDF material, some as much as 40mm thick. With consumer veneered models, they are prepared both inside and out with veneer that guarantees their stability and long life.

The accuracy of the joints, together with modern bonding agents creates one homogeneous, flawless structure that acts as the ideal, inert platform for the drive units to deliver pure, uncoloured audio.

Leaves of the world’s premium veneers, all sourced from sustainable forests, are hand-selected and matched so that each cabinet face appears as a perfect mirror image. They are finished with a delicate lacquer to give a faultless, deep and lustrous sheen that will compliment both modern décor and fine, classical furniture.

ATL Technology

The source of PMC’s legendary 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.

  • More detailed, more natural

  • Full, rich sound at any volume level

  • Deeper bass from a smaller cabinet

 

Laminair

PMC’s Laminair™ aerodynamic vent takes audio performance to the next level, by applying ATL aerodynamic principles from high-performance engineering used from F1 to Le Mans and creating an even smoother, laminar airflow at the exit from the transmission line.
ATL designs involve air moving at high speeds and under pressure. Reducing turbulence and drag at the ATL vent reduces resistance, increases efficiency, eliminates air noise and provides bass with supreme timing and the widest possible dynamic range. The combination of ATL and Laminair takes audio quality to unparalleled new heights:

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.

  • Faster, cleaner bass and higher definition sound throughout

  • Turbulence is eliminated, increasing the efficiency of the ATL

  • Removes air noise — only the music remains

  • Higher maximum output and bass with supreme timing and dynamics

 

Drive Units

Many speaker manufacturers start with a driver — someone else's driver, an OEM design — and go from there. That approach is not an option at PMC. Our Advanced Transmission Line™ designs require a driver specifically tailored to its parent cabinet to produce the high-resolution, ultra-low-distortion performance our customers expect of us. As a result, our drivers yield a natural, pure, uncoloured sound which you can trust as a true audio reference. Why would you want anything else??

Crossovers

When designing the fact crossover, the value of the capacitors was first calculated, and then the best-sounding example – chosen from many different manufacturers – was selected.

Upon delivery, each capacitor is tested to ensure it matches the required specifications and a record of the measurement results are kept. Pairs of capacitors with identical specifications are used in each pair of loudspeakers, ensuring that their characteristics are indistinguishable.

The capacitors are then soldered, bonded and anchored by hand onto the military-grade crossover circuit board, which is also individually inspected and tested.

The crossover can then be considered for installation, but only after its performance characteristics are approved following both critical listening tests and exacting computerised measurements.

But it’s not just capacitors and crossovers; every single component of PMC’s fact loudspeakers is subject to the same rigorous test procedures, ensuring that each loudspeaker is a precise replica of our reference.

This holistic approach, where all design elements are treated with the same significance, is a signature of the fact’s design excellence. This guarantees supreme power handling and ultra-low distortion, both of which play a major role in the exceptional clarity and wide, three-dimensional soundstage to be enjoyed across a wide listening area.

 

In Hifi Gear we have had great results with the PMC speakers with Naim amplification. The PMC Twenty5 23i pairs brilliantly with the Naim Supernait 3 offering a superb depth of sound. The detail is clean and razor-sharp thanks to the newly developed twenty5i high-frequency driver which has trickled down from the Premium Fact series of speakers. The midrange is natural and responsive in part down to its ultra-light driver which has been specially designed to couple with the ATL bass-loading technology. Where the PMC is very different to most speakers is its ATL bass-loading technology, this helps the 23i bass performance stand out against other similar-sized speakers. The bass is fast and clean and at low volume still offers the same defined, balanced sound thanks to its ATL design. When listening to this combination, whether using a Naim network streamer like the NDX2 or a turntable such as the Rega Planar 6, you get a clarity that's hard to beat with excellent dynamics and imaging. These speakers are on display in our store and can often be heard on demo. If you'd like to have a listen, please call or email the shop to arrange a listening session.

 

Who is PMC?

Founded in 1991 by Peter Thomas of the BBC and Adrian Loader of FWO Bauch. The combination of knowledge and a life-long passion for music led to the production of PMC’s first product, the BB5-A, an active main studio monitor. This design was snapped up by the BBC Maida Vale and Metropolis Mastering and remains the world’s reference, used by Prince, Stevie Wonder’s Wonderland Studio, Hospital HDTV Broadcast London and renowned classical labels such as Decca and Harmonia Mundi. Many of today’s movie themes have been crafted using PMC, by such eminent composers as Henry Jackman, Thomas Newman, Tyler Bates and John Debney.
