MarkAudio Alpair 5G (UTAGlass Diaphragm) Glass Diaphragm Driver Unit a pair

The Alpair 5G is a unit that was created to push the playback of full-range speakers to a higher level of resolution. The sound is not flashy. However, once it starts to sound, you can naturally see the outline of the sound and the depth of the space that you were not aware of before. It feels like the resolution of the video has gone up a notch. Alpair 5G quietly presents such a "quality difference".

Fundamentally review diaphragm materials

The diaphragm of a speaker requires conflicting conditions: lightness, transmission speed, and internal loss.
In order to achieve both of these in a high dimension, Alpair 5G uses UTAGlass (ultra-thin special glass) as the diaphragm material. This material has a very fast transmission rate of sound and a light mass. In addition, it has moderate internal losses, which is exceptional for glass.

Microscopic sound drawn by a 100μm diaphragm

The UTAG diaphragm of the Alpair 5G is molded as thin as thin as to about 100 μm, which is the limit for this size. The combination of Markaudio's unique cone profile and magnetic circuit design results in a very well-organized timeline characteristic from the rise of low frequencies to the disappearance of high frequencies. As a result, the playback band naturally extends to 40kHz, allowing only minute information to emerge without irritation to the ear.

When the time axis is in place, the music becomes natural

The sound of an instrument rises, resonates, attenuates, and ends—only when this flow is accurate can it become its original tone. UTAGlass accurately draws the attack through lightness and high transmission speed, and does not muddy the aftertaste with proper damping. Therefore, the sound of the Alpair 5G is not stressed, but just quietly conveys the structure of the music itself.

Uniform and quirk-free damping characteristics

One of the reasons why the Alpair 5G's reproduced sound feels transparent is the uniformity of the attenuation. Only a specific band does not remain or, on the contrary, it disappears suddenly, and the sound disappears naturally and in the same way in all bands.
This characteristic supports a sound field with low coloring and good visibility.

Die-cast aluminum frame to support the attack

To precisely support this agile vibration system, the Alpair 5G features a die-cast aluminum frame. By increasing the rigidity of the frame, the movement of the UTAG diaphragm is converted into sound without waste, resulting in faster rise and clarity of localization.

The experience of increasing resolution

The sound of the Alpair 5G is not the type that overwhelms with the amount of information. The superfluous is stripped away, and only the necessary sounds appear at the right time. As a result, the nuances and atmosphere of the performance are naturally conveyed without being conscious of it. This is a sense of resolution unique to the next-generation full range.

The T/S parameter is a basic numerical value that indicates how the unit will move and the enclosure design is appropriate.
The overall balance determines the individuality of the sound rather than the numbers themselves.
