The Twenty5 24i largest two-way speaker in the range for when a larger, more powerful speaker is required. The 24i is still a relatively compact floorstander that far exceeds expectations. The 24i will completely fill even larger-sized listening rooms with sound which could easily be mistaken for that of a much larger three-way speaker. The 24i's sleek cabinet houses a 19mm fabric soft-dome wide dispersion tweeter and a 6.5-inch cast alloy bass driver, which is enhanced by PMC's infamous Advanced Transmission Line design. This allows the 24i to produce levels of bass depth and detail which is completely unheard of in speakers of this size and price. The 24i is capable of stunning, open highs, detailed mids and perfectly balanced bass which you can not only hear but feel.

 

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 Vent

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 Laminar 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.

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.
