Technology
DEEPER CLEARER CLEANER BASS & MORE
• Greater detail & more natural
• A 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.
Laminair - smoothing the air flow
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
The largest two-way speaker in the range, the twenty5.24i delivers compelling life-like performances with realism, precision, bite and power. Even in medium-to-large listening rooms, its seamlessly integrated drivers and ATL™ saturate the space with music, giving you a hi-fidelity experience like no other in a slender and graceful cabinet design that will delight your senses without dominating your room. With the grilles in place, the twenty5.24i produces a sound that many could mistake for that of a three-way speaker.
