1 MarkAudio Alpair 5G (UTAGlass Diaphragm) Glass Diaphragm Driver Unit

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 sound played by Alpair 5G feels transparent is the uniformity of the attenuation. Instead of only a specific band remaining or suddenly disappearing, the sound disappears naturally and in the same way in all bands.
This characteristic supports a clear sound field with little coloration.

Aluminum die-cast frame that supports attack

In order to accurately support this agile vibration system, Alpair 5G uses an aluminum die-cast frame. By increasing the rigidity of the frame, the movement of the UTAG diaphragm is converted into sound without wasting it, bringing out the speed of rise and clarity of localization.

The experience of increasing resolution

The sound of Alpair 5G is not the type that overwhelms you with the amount of information. Extraneous things are removed, and only the necessary sounds appear at the right time. As a result, the nuances and atmosphere of the performance come through naturally without you even being aware of it. This is a sense of resolution that can only be achieved with the next generation full range.

T/S parameters are basic numbers that indicate how the unit moves and guide enclosure design.
The overall balance, rather than the numbers themselves, determines the individuality of the sound.
