In 1950, United States C 5. Bocciarelli proposed the 'constant charge' law P. Walker independently developed the same theory at the same time, and applied it to the famous Quad electrostatic loudspeaker design. So far, the embryonic form of sound has been formed. With the continuous improvement of people's living standards, the pursuit of quality of life has been constantly improved. Sound has gradually become an integral part of the home theater.

▲ The front of the packaging box has unique feelings. It is Van Gogh's famous work "Night of the Stars and the Moon", which is full of artistic feelings. This kind of outer packaging design is rare in scientific and technological products. It can be seen that this is also a company based on feelings.

▲ The Theatre Box is wrapped in a long square box, which has a total of black, red, blue and white four color boxes. The small knitting hand is a blue box, with various two-dimensional codes attached on the outer package.

▲ The overall blue color of the Theme Box is bright, which is very attractive. It is surrounded by a metal grid, and the top uses a virtual capacitive touch button. Four full audio speakers and an active bass speaker are integrated on four sides. Such acoustic architecture can let the experienced people experience the same sound effect in different locations.

▲ The manufacturer also considered the user experience under the inner packaging. A blue hand strap ensures that the box can be lifted easily when the machine takes out the box.

▲ Accessories include: power adapter * 1, 3.5MM audio cable * 1, manual * 1, warranty card * 1. It should be noted that it is still a trial version. So its warranty card and instructions are all in English, which makes us feel embarrassed to fail in English.

▲ The power adapter outputs 15V, 3.0A, and the overall color of the wire is white.

▲ The body size is 260mm * 85mm * 110mm, and the net weight is 1.6KG. Adult men can easily take it away with one hand, but it is difficult for women to carry it with one hand, after all, to ensure its sound quality and endurance. The manufacturer does not hesitate to use materials at any cost. The metal sound transmission grid is surrounded by fine holes.

▲ The bottom of the Theme Box is made of anti-skid silicone, which has a skin like touch, and has its detailed parameters and functional connection methods.

▲ The bottom physical keys are as follows: power， Bluetooth, power interface, 3.5mm audio interface, soft button experience. It is not stiff, and when it is turned on, the power key will have a color prompt, and will be accompanied by a very magical sound. It should be noted that the audio will automatically shut down when it does not work for a long time, so as to ensure its long-term endurance.

▲ It should be noted that there is sharp metal exposed in the wire mesh, and the details need to be optimized.

▲ The top virtual keys are as follows: NFC、 Volume increase/decrease, switch, mute, and answer the phone.

▲ The response of virtual keys after clicking has a certain delay, about 0.1S-0.3S, but does not affect the use. It should be noted that the switch key can only be used when Bluetooth is connected, but it cannot be used when wired.

▲ Four 2-inch full audio speakers and one 3-inch active bass speaker. In the actual experience, the three frequencies are relatively balanced, the low-frequency diving is powerful, the intermediate frequency is prominent and natural, and the high-frequency is clear without burrs.

▲ The biggest highlight of the Theme Box is Q3D full silence. The so-called Q3D panoramic sound is a virtual 3D sound effect technology based on sound field wave synthesis. Unlike the traditional 3D sound effect technology, Q3D full scene sound no longer depends on the combination sound system to create the psychoacoustic illusion of sound source perception, but on the physical reconstruction of sound field waves. Based on the principle of Hagen, it simulates the diffracted wave sound wave with highly restored natural sound effect. The sound effect thus formed has the advantages of small sound generating surface, wide transmission range, high separation, strong sense of time and space, and anti-interference. And it's also a natural 360 degree surround sound. Unlike traditional stereo groups, listeners can only perceive good 3D sound effects when they are constrained to a preset sound effect focus. The Q3D panoramic sound allows the listener to feel the same virtual 3D sound effect at any point around the device.

▲ In the actual experience of its Q3D panoramic sound, the author changed different positions. No matter where in the room, the sound heard is the same full and natural. Its frequency range is between 20Hz and 20KHz, and its signal-to-noise ratio is 90dB. 90dB is equivalent to the signal power being 10 times of the noise power, which is very good. As a single sound system, it has a sense of space comparable to the 5.1 sound system. For the expressive power of details, the single sound system is superior to others.

▲ The Theme Box has a built-in rechargeable high-density lithium battery. When fully charged, its endurance can grow up to 20H, but its small size has big content. However, in the actual experience, the external power supply and the built-in battery play at the same volume. When the built-in power supply plays, the volume will decrease to a certain extent.

At the end two thousand It was a walkman in 2003. I put in tapes and listened to songs every day. Experiencing the joy that music brings to us. Time flies by. Now I am in my late thirties, and technology is constantly improving. But I always feel that I can never find the original feeling again. Time flies, music is still the original music, and people are no longer the original people.

advantage:

one High appearance and powerful appearance.

two . Battery life;

three The sound quality is very good under the single sound category;

four Excellent tri band;

five Diversified connection forms.

Disadvantages:

one The details optimization needs to be strengthened. The metal mesh of this model is exposed;

two . Built in storage is not supported and cannot be expanded;

three The manual is in English!!!

Comprehensive evaluation: As a single stereo, the sound quality of the Theatre Box is really impeccable, and it is undeniable that its high sales in Amazon is due to its excellent quality. However, as for China, the price of 1999 is on the high side, if it can be more friendly to the people. That will certainly be accepted by more people. The manual will be changed to Chinese, and the details will be optimized and strengthened. This product is also a masterpiece.
