The 23 has proved to be the most popular model in our 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, it will make the best of even affordable source electronics, and, coupled with high-end amplification, will truly excel.
Technology
PMC’s unique (Advanced Transmission Line) enclosures have taken loudspeaker design to the highest level, using sophisticated cabinet construction, proprietary drive units, and patented absorption materials and techniques. The benefits are enormous compared to the relatively simple sealed and ported designs currently available elsewhere.
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 air flow 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:
- 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
ATL – Advanced Transmission Line
The Unique Benefits:
- More detailed, more natural
- Full, rich sound at any volume level
- Deeper bass from a smaller cabinet
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.
