Fans familiar with the Swiss audio brand Piega should know that the flat diaphragm tweeter is the biggest feature of his speaker. The factory is called “Linear Drive Ribbonâ€, which is not only extremely high-frequency extension, but also bigger than the average tweeter. Many of the diaphragm area also makes the Piega speaker's medium and high frequency energy feel particularly thick.
In 2000, Piega developed the world's first Coaxial Ribbon System to make it famous! However, in recent years, the Hi-End market feels that Piega is relatively quiet, but this year, Piega in Switzerland has returned to the Hi End market! It turned out that the former agent would focus on the multi-channel series. However, after the agent took over the big sound, it turned its focus back to the two-channel Hi End speaker series. 
This Piega sent two original representatives, in addition to highlighting the core features of the Piega speakers to the market, it also introduced the latest four-piece flagship speaker, the Piega Master Line Source. 
On the same day, a pair of Piega Coax 120.2 floor-standing speakers were placed in the listening room of the large-scale audio, and the silver-white aluminum alloy case was designed with a simple arc-shaped line.
Piega with beautiful views
Let's take a look at this Hi End loudspeaker company from Switzerland. The headquarters is located on the shore of Lake Zurich. The scenery is very beautiful. How beautiful is it? The original factory representative took out the iPhone 5S directly to show the lake scenery that he can enjoy when he usually goes to work, which is really a beautiful and beautiful scenery! Founded in 1986, the company was founded by Kurt Scheuch and Leo Greiner. The two founders are good at speaker technology and a good at design. So the result of the two complement each other is a boutique speaker product.

One of the original representatives of Taiwan who came to Taiwan was the son of the founder Leo Greiner, Manuel Greiner. Is Manuel visiting Asia to say that Leo is going to retire? Manuel denied and said that his father thought that if he didn't work, he would be very old, so he was still contributing to the company. He only took part in the hard work. As for the other factory representative, he was the vice president of marketing and marketing. Manager Martin Klaassen.
Swiss-made, hand-made, coaxial aluminum belt unit
Manuel Greiner emphasizes that Piega is a "very large trumpet". If other brands of speakers are to emit the same volume as the Piega, the cabinet should be at least 30% larger.
At the beginning, Manuel emphasized to us that the main features of Piega are Swiss-made, hand-made and coaxial aluminum belt units. Why not reduce costs in production outside the country? The answer is very simple. Just like a Swiss watch, Piega is going to take the exquisite route of origin and hand-made, and the Piega's speakers are not capable of being produced in general factories. For example, the aluminum speaker cabinet is difficult to manufacture. It is said that only three manufacturers in the world have the ability to make. 
Not only is it difficult to make, but also avoids the sound of the box itself. Because the hand of the hollow speaker box is used to knock out the sound of the big and the bell, the original factory especially strengthens the internal structure of the box. A number of special dampings have also been added to eliminate the resonance problem, and the rigidity of the aluminum alloy case is very good, so a large volume can be emitted with a small box. That's why Manuel emphasizes that Piega is a "very large little speaker". If other brands of speakers are to emit the same volume as the Piega, the cabinet should be at least 30% larger.
Piega Coax 120.2 floor horn, every small place is very delicate
As for Piega's most proud center-high-tone coaxial aluminum belt unit, it seems that the unit size has become larger in terms of product catalogue. The performance data provided by the original factory is quite excellent, with an ultra-wide frequency response of 400Hz~50kHz. And the efficiency is greater than 100dB. This large-area aluminum flat diaphragm is very difficult to fabricate, especially in the shape of a film (only 0.02 mm thick). When the diaphragm reciprocates, it is likely to have a ringing phenomenon, but Piega has successfully solved this problem. How did it do it? The original factory attitude is very low-key, only that the production technology is very difficult, and it is a secret that cannot be circulated!
However, we can observe from the outside, the surface of the diaphragm is pressed with a grid pattern, and the special perforated frame that Manuel tells us helps to enhance the rigidity of the diaphragm. Moreover, only one or two people in the original factory will make such a coaxial aluminum belt unit by hand. It is not easy to train new people. The units produced in the first three months of the training period are all failed, and the production difficulty is really high.
New flagship Master Line Source floor speaker
The topic came to another focus, which is the latest flagship speaker Main Line Source speaker from Piega: 
Piega's latest flagship Master Line Source four-piece floor speaker "prototype", the official version will be more beautiful
The design of Master Line Source is very different from that of the previous Piega. It has a four-piece design. The left and right channels have a medium-high-pitched floor-standing speaker and a bass-floor speaker. The cabinet is also made of aluminum alloy. The height is about 175. The total weight is up to 420 kilograms, because the volume is not too small, and you need enough listening space to put it in.
The speaker itself is designed for the Dipole 39 unit Dipole, yes, you are not mistaken! It is 39 units. The high and middle sounds are arranged in a straight line. They belong to the line source design. The two units are mounted on the same thin aluminum alloy panel, including 24 aluminum belt trebles (12 front/12 rear) and 9 aluminum. With a midrange, the other 6 woofer units are mounted in a separate cabinet. This 22cm woofer is a custom product from ScanSpeak.
The whole system adopts passive design with impedance of 4 ohms and efficiency of 94dB/W/m. As for the frequency response and the recommended amplifier power, the data has not been released. Under the inquiry, it was because we got the prototype production. The catalogue data, there should be detailed data. The confirmed version of the Master Line Source has been officially produced, and Manuel said that the official version is more beautiful than the photos on the catalog! What is the price that everyone cares most about? The agent's big sound revealed that the price is about 200,000 US dollars, but there is no stock at present. Interested enthusiasts please be patient!
