In today's cloud audio deluge, we can see two or three smart audio models called HIFI at random on the crowdfunding page, HIFI has become the least valuable advertising words, so the intelligent cloud sound source has become a choice for many hardware companies that do not have the ability to develop electroacoustics to make product differentiation. Of course, there are also teams or companies that have made great achievements in acoustics that stick to the breakthrough of traditional technology and use a new advertising word to refresh users' understanding of sound quality. THEATRE BOX chooses panoramic sound.

The panoramic sound here has nothing to do with Dolby ATMOS. Instead, it uses self-developed Q3D halophony technology to carry out physical reconstruction through the sound generating position of the unit and the sound field wave emitted, so as to achieve a high sense of time and space and high separation. It is different from the traditional single cavity stereo small box that is easy to identify the sound position and has a large limitation on the listening range, The maximum sound coverage of THEATRE BOX with Q3D halophony technology is 150 square meters.

Besides, the development team of THEATRE BOX is different from the traditional development team or company. The core members of THEATRE BOX can definitely brush my heart:

This team is an all star team for the domestic crowdfunding project team, especially the former senior vice president of sony entertainment film and television business, Hideki Ruzaki, as the chief technology officer, and Herbert Waltl, a sound consultant who has won the Grammy Award for sound effects, have laid the foundation for the outstanding performance of THEATRE BOX.

Then look at the product. It's still a little amazing when we just got there. The whole packaging style is also European and American. A conductor's silhouette in Van Gogh's "Starry Moon Night" creates a dream like experience.

There is no Chinese content in the whole package. The official attached a printed Chinese manual. It is said that THEATRE BOX has caused quite a stir in the European and American media. It seems that the western countries that pay attention to copyright awareness and the characteristic traditional audio are more suitable for their market environment.

On the back is a brief introduction of the product. The product's appearance and color matching, several main functions, and the QR code of foreign social platforms show that the evaluation product is blue.

The imperial position of traditional surround sound is the central position of all surround units, while the THEATRE BOX can be located anywhere around.

The package is in the form of a jacketed shell, and the inner shell is equipped with a braided handle. It is unknown whether the blue braided handle is intended to match the color of the product. It can be seen that the details are very considerate. The upper cover of the package uses a hard foam pad with holes.

Opening the foam pad is the user's manual and the main body of the product. It is a consistent humanistic hidden rule for the packaging of European and American digital products to let users read the product manual first. Some products in Taiwan also put the product manual on the outermost layer of the packaging. The main body of the product is also equipped with a blue woven handle to facilitate the removal of the product.

The lower layer is also a partition of hard open cell foam, with accessories installed.

The entire packing list is very simple: THEATRE BOX、 Power cord, DC power adapter, AUX3.5mm audio cable.

The DC power adapter is of very good workmanship, and the non big end design can adapt to more sockets and plug banks.

Then look at THEATRE BOX. The whole box is blue, so blue that even the logo can not be recognized from a distance. It is also a fluorescent blue. The plastic shell material is used, but the spraying is quite metallic. The 1.6kg hand feel is heavy, and the size is 260mm × 85mm × 110mm.

Different from the traditional small desktop box, THEATRE BOX is wrapped with 360 degree punched iron mesh because of its special unit distribution.

The back is also embedded with a whole piece of perforated iron mesh, without any screws, so it is difficult to disassemble without damaging the appearance. The bottom of the back is equipped with physical keys and interfaces, and the whole audio has no obvious reference on the front and back.

A row of function keys is set at the top of THEATRE BOX, which can realize remote operation after connecting with the intelligent terminal, including telephone, mute, previous song, next song, volume decrease, volume increase NFC。

The back is equipped with power key, Bluetooth key, power interface, and aux 3.5mm audio input.

An indicator light is set on the outer circle of the power button to display the existing status through the red and white breathing lights. When the Bluetooth key is pressed in the power on status, the light will switch between red and white to enter the pairing status.

The bottom of THEATRE BOX is equipped with a whole rubber anti-skid pad, which is also the same as the color matching of the machine. It can be said that it has pursued perfection in details. Different materials want to achieve consistent color matching without error, and have high requirements for manufacturing process.

Turn on the power supply, and there is a ring-shaped power on prompt tone. Press the Bluetooth key, and turn on the Bluetooth of the phone to pair with THEATRE BOX, There will be voice or effect tone prompts when THEATRE BOX is turned on or off, Bluetooth pairing, fully charged, or low battery. Bluetooth can not only push music, but also answer calls. The built-in mic of THEATRE BOX is of high quality. Unfortunately, Chinese people do not have the habit of playing and making calls outside.

You can also directly connect to the playback source through the aux3.5mm to turn on the sound. What's the difference between the THEATRE BOX and the traditional dual channel sound? Let's first look at the sound wave principle of the traditional sound:

The listening phoneme of traditional dual channel audio is mainly in the front. Once the listener goes to the back of the audio, the sound waves are mainly refracted back, so the larger the space is, the worse the effect is. The sound gap is very large, and the surround angle of the left and right channels is very narrow, so it is difficult to have a sense of space and surround, especially when watching movies, The sound effect is very poor.

Take a look at the unit distribution of THEATRE BOX. Four full frequency units are distributed in the left, front and right directions. At the rear is an active bass unit.

This results in a very wide range of sound waves during sound generation. In addition to the non directional bass, the whole sound wave is scattered to create a good sense of space. When watching a movie, the distribution of four units makes the sound channel surround angle very large, so the transition of sound channel information is very obvious. The low frequency from the large sized bass unit brings a sound effect unmatched by ordinary dual channel sound.

Music sense:

The sound source adopts MBP 17, and the analytical power and sense of space are better than the national brick, after all, the 2w+Apple flagship of that year.

Sister Drum - Zhu Zheqin DTS WAV

The low frequency of the prelude is very thick. Although the drum is not deep, the sense of quantity is very strong. Zhu Zheqin's hoarse voice and accompaniment are just right. Although the treble part is not very bright, it does not affect the performance of the whole music.

Faye Wong - Sky Lossless WAV

The highlight of Faye Wong's song is the empty inspiration in the treble part. Unfortunately, the four full frequency units of THEATRE BOX must be unmanageable. The treble is slightly dim, and other parts perform well. Although there is no empty inspiration, there is a lot of space.

Down By The Salley Gardens Fujita Huimei Lossless WAV

This song is based on my personal preference. Fujita's voice always gives me a sense of European autumn bleak warmth. The whole song is full of piano music, and the piano performance is full and tense. The melody dominated by mid frequency is very interesting by THEATRE BOX, and the diffuse sense of space adds a lot of points.

Viewing and Listening:

All movie sources are original disks or remux movie sources, which are output at the av end of the Android box.

Avatar:

Avatar is a sub era audio track, but it can only be output in a degraded manner without decoding the power amplifier source. When THEATRE BOX plays the source, it has a strong sense of energy and the smell of a cinema box. Especially when Jack, the main character, captures the Icalan pterosaur, the sound pressure when his wings flap comes from his face. When the big event is big, the sound track information is also very rich, as if he is in the jungle.

Black eagle falling:

The old war movies are full of scattered shooting scenes, which greatly tests the surround performance of dual channel audio. If you try to watch the TV with its own unit, the sound of guns is thin, there is no stereo sense, and the left and right channels have a poor sense of information. After the THEATRE BOX is used, the whole sound field immediately becomes three-dimensional, and the extremely low frequencies of guns and other things come to you, and the surround information is rich, The trajectory of the bullet is easy to identify. Although the bass is slightly loose, it is commendable that small boxes can achieve this performance.

Summary:

From listening to music and watching movies, THEATRE BOX Obviously, it is biased towards middle and low frequencies and sound effects. That is to say, it has a very good performance for rock and roll, percussion music, and concerts where the main intermediate frequency pursues sound field and sense of space. It is far more than products of the same price. In addition, the bass brings a surging sense of energy when watching movies, with an ultra wide left and right channel span and a very good sense of surround. It is very suitable for users who need to listen to and watch movies, As a desktop multimedia, we are very comfortable. We are looking forward to the next generation of ACEMILE products, which can strengthen the treble part, and even consider cloud audio sources to create the most competitive intelligent cloud audio in China.
