Description

The Alpair 5G marks a Markaudio first in loudspeaker design, introducing a diaphragm made from Ultra Thin Acoustic Glass (UTAG). Developed by Glass Acoustic Innovations Co., Ltd (GAIT) using Dinorex UTG® by Nippon Electric Glass. This material offers an alternative, intriguing sound and listening experience to metal and paper cone technology. Glass technology delivers a faster sound wave propagation across the cone surface, increasing the transient response.
With a near flat response from Fs to 10KHz and extended rising output to a remarkable 40KHz, the Alpair 5G achieves levels of detail rarely found in full-range drivers. Its unique glass diaphragm reduces internal resonance and reverberation while remaining resistant to humidity, temperature fluctuations, and long-term deterioration.
The Alpair 5G integrates a precision engineered suspension system using a mixed grade butylbased material for low mass and high stability with an advanced, low-distortion motor design with pure copper coil, and a cast aluminum alloy basket to minimize vibration and distortion. These carefully-engineered elements work in harmony with the UTAG diaphragm to produce a driver that is not only lightweight and responsive but also acoustically stable under demanding conditions. The cone and dustcap are provided by Glass Acoustic Innovations Co. Ltd (GAIT), and we extend our thanks to their team for their engineering, development, and manufacturing expertise in pioneering this new material. Their collaboration has been instrumental in realizing
the Alpair 5G.
This combination of advanced materials and engineering makes the Alpair 5G a benchmark in full-range loudspeaker innovation.
