PMC TWENTY5.21

Second-hand. In excellent condition. No noticeable signs of wear. Comes with manual and original packaging without internal protection.

The PMC twenty5.21 proves that exceptional performance can be packed into a compact format. Despite their small size, their capabilities are outstanding. The ATL (Advanced Transmission Line) system, combined with Laminair technology, delivers speed, weight, and transparency, providing bass depth that surpasses any other speaker of similar dimensions.

Whether placed on a shelf or dedicated stands, the twenty5.21 excels with any music genre. Their articulate midrange, crystal-clear and open highs, and deep bass allow them to fill small to medium-sized rooms effortlessly.

The backward-tilted design, a hallmark of the twenty5 series, is eye-catching not only for its aesthetic appeal but also for its technical purpose. This shape reduces the buildup of internal standing waves, enhancing sound quality. The twenty5.21 features a 27mm soft-dome tweeter and a 14cm treated paper midwoofer. While these components might seem standard, they result from advanced engineering inspired by PMC’s Fact range, delivering superior performance.

After a short break-in period, the twenty5.21 reveals their full potential. Initially, they might appear slightly limited in overall balance and bass depth, but proper setup transforms them entirely. Positioned about 15cm from the rear wall, they achieve impeccable tonal balance. Careful toe-in adjustment maximizes soundstage width and solidity, while biwiring improves transparency. Using sturdy stands like the Custom Design 104 Signature or PMC’s dedicated stands further elevates their performance.

When optimized, the twenty5.21 offers a wide, layered soundstage, impressive in scale and power, especially considering their modest 33cm height. As the volume increases, they gain bass presence, authority, and dynamics, perfectly adapting to various listening levels. Even at high volumes, the sound remains controlled, demonstrating remarkable consistency and detail retention.

Their detailed resolution, precise timing, and even tonal balance make them suitable for a wide range of music genres. The twenty5.21 allows the music to flow freely, delivering an immersive and engaging listening experience.

PMC shows that at this price level, it’s possible to create stand-mount speakers that rival higher-end models. Thanks to advanced technologies and high-quality materials, the twenty5.21 stands out for their ability to reveal every musical nuance without ever drawing attention to themselves, acting as perfect intermediaries between the music and the listener.
