twenty5.21i

Category: TWENTY5I

Although the twenty5.21i is the most compact model in the new range, there’s nothing small about the sound, which has the impact you’d expect from a much larger cabinet, thanks to PMC’s ATL technology.

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

Although the twenty5.21i is the most compact model in the new range, there’s nothing small about the sound, which has the impact you’d expect from a much larger cabinet, thanks to PMC’s Advanced Transmission Line technology. The speaker is ideal for use in small-to-medium listening environments where space is at a premium, but where you still want detailed bass, ultra-realistic mids and delicate highs with maximum musicality. Equally happy mounted on a stand or a bookshelf, the twenty5.21i offers maximum flexibility for placement, and also makes an excellent choice for effects speakers in an immersive sound system.
