Before the evaluation, the first thing to note is that KAISFLY is definitely not a sound bar. The box size similar to the TV cabinet is not even smaller than a single floor speaker. The huge shape gives the unit and sound sufficient breathing space, bringing unprecedented audio-visual feast.

Although KAISFLY's crowdfunding in JD has not yet ended, and even the mass production machine has not yet been offline, I can't help but ask for KAISFLY's engineering prototype to see the style of this professional audio-visual all-in-one machine. Because the evaluation is an engineering prototype, the appearance and workmanship have a lot of entry and exit with the mass production version, and I have the right to taste it.

Most of the traditional sound bar products adopt the configuration of full frequency unit+low-frequency unit. The performance of mid bass is acceptable, but the high pitch is dim. Because these products are only derivatives of TV speakers, they do not attach importance to the performance of music, let alone the HIFI experience. For the sake of beauty and placement, the width is about 10 cm, The narrow box can not give the unit sufficient breathing space, resulting in low frequency without sense of quantity and diving. The popular so-called split TV is just a simple combination of some TV hardware modules and sound bar, which can not bring qualitative audio-visual improvement.

KAISFLY is a smart speaker that adopts the video decoding scheme of Linux platform 1185 chip. The unit configuration of 4 IF units+2 tweeters+bipolar low-frequency achieves balanced tri frequency performance, and he is named SOUNDBASS.

KAISFLY's engineering prototype adopts a relatively clear symmetrical design of left and right units. The front cover of the mass production machine is an integrated one. The box body is made of traditional wooden box materials, and the overall weight is up to 17 kg, so as to avoid box resonance when playing the sound source.

The box size has also reached an astonishing 115cm * 40cm * 12cm, and the depth of the mass production machine has been improved to 34cm. However, it is also a real giant in similar products, because the unit configuration is high, and the stroke of the low-frequency unit needs enough breathing space in the chamber.

KAISFLY's box adopts a closed structure, which is more flexible in low-frequency performance. The unit configuration is very generous. It uses four IF units, two silk film dome tweeters, and two subwoofers. Low frequency is the soul of the cinema. KAISFLY's unit configuration undoubtedly attaches great importance to the performance of low frequency.

Since the ELF has almost no directivity, the sense of surround and presence of the cinema effect depends on the dispersion of the low frequency. KAISFLY low-frequency unit ingeniously uses the refraction of the bottom and the back wall to diffuse the low frequency in the entire audio-visual space, which also makes KAISFLY need to be positioned about 10cm near the back wall.

The back is very simple. The interface panel of the speaker is between the two open bass transmitters.

KAISFLY's interfaces are not rich. The two input sources can meet the source input of TV and box, and the power switch and USB setting on the back is not particularly reasonable. Because KAISFLY needs to be placed against the wall, the utilization rate of the power switch will not be very high. The USB device seems to be equipped with an extension cable or HUB. These problems are not problems in the traditional SOND BAR, However, as a larger SOUND BASS, it is structurally redefined.

KAISFLY's remote control is the most textured audio-visual equipment I have ever seen. It is made of aluminum alloy profiles.

The keys are also metal chrome plating process, but the price paid is that the hand feel is quite hard. Because the input frequency is not high, it will not cause hand fatigue. The whole key panel is divided into several areas according to the function. It is worth noting that KAISFLY provides a convenient remote control switching mode for the input source. One key switches the audio source of AUX optical fiber the machine, while EQ, KAISFLY provides four EQ modes, namely, HIFI, music, film and news. After actual measurement, the effects are very different. Because KAISFLY is equipped with two 5-inch ELF units, it may have a slightly heavier sense of low frequency, so users can adjust the level of low frequency through the low-frequency ＋－ on the remote controller according to their taste, which is very user-friendly.

Because it is an aluminum alloy shell, the remote controller cannot use the traditional structure of the battery compartment. The battery compartment can be seen by removing the rear cover plate and pulling out the bottom plate. It is very convenient to remove the battery compartment. It must be noted that the screws are easy to lose. It is hoped that KAISFLY will be more optimized in structure in the future and adopt a screw free design.

Nowadays, most of the Android platform smart TVs launched by major Internet companies or content companies provide optical fiber output, while traditional TVs are at least equipped with RAC audio output or AUX3.5mm audio output, which can be connected to KAISFLY simply by connecting. It should be noted that the digital optical fiber output of smart TVs needs to be set in the menu.

KAISFLY comes with its own Linux system. Realtek 1185CD chip is used instead of Android system. The reason is that Android system requires powerful CPU to decode high-definition video, and the high configuration investment brings about 16bit 44.1k audio limit and unsatisfactory picture effect, which is why many professional hard disk players still use the Linux platform, Of course, Android is the general trend after all, but this is the last word.

Another reason is that because of the blocking of a certain TV, the program source of box products is in danger, and there is positioning duplication with smart TV. For online video sources, KAISFLY has chosen another path.

It is a LAN sharing protocol. The mobile intelligent terminal is not among some electronic blocking objects, but KAISFLY is compatible with many sharing protocols such as AIRPLAY DLNA UPNP. Through simple settings, the pictures and sounds of the mobile terminal can be delivered to KAISFLY.

In order to share the LAN smoothly, KAISFLY has configured 2.4g/5g dual band WIFI, which is sufficient for the projection of high-definition program sources, although it uses a 100M LAN interface.

The final effect of the speaker still lies in the audio-visual effect. KAISFLY is positioned at the smart speaker in the living room, with a built-in Hi Res Audio player. In addition to supporting mainstream lossless audio such as WAV FLAC APE AAC with a sampling rate of 24bit 192khz, it also supports power on detection of audio files in USB storage devices, automatic playback, and use away from the TV terminal.

By playing Faye Wong's sky, Cai Qin's ferry, my heart is still familiar with lossless music, KAISFLY's sound field is very three-dimensional. The middle and high tones reach the level of entry-level HIFI, showing the original flavor, especially the ferry prelude. Because the two 5-inch extremely low frequency units have good drum volume, diving and texture performance, and the overall performance is similar to the JBL style, suitable for listening to pop music, percussion, blues, jazz and other styles of music.

The 1185 scheme will not repeat the support for video files. After all, it is the most popular and mature video decoding chip scheme, and it also supports the next generation of audio tracks, KAISFLY has added DSP surround sound effect technology, and its performance in film sound effect is very outstanding. Regardless of the richness of surround details, the low-frequency second kill of low-end satellite 5.1 speakers is not excessive.

Jianyu is a modern martial arts film that was discovered by accident and has outstanding low-frequency sound effects. It uses the sub era track of truehd 7.1, In the process of playing Sword Rain, KAISFLY's moves are surrounded and the interpretation of thunder in the film is very impressive. If you want to pick out some flaws, it is because of the outstanding performance of low frequency, which leads to the implicit inclusion of white. It is hoped that in the subsequent firmware, the original mid channel information will be enhanced, and the effect will be more outstanding.

In addition, KAISFLY's four EQs have obvious effects. HIFI mode is required for lossless music, and movie mode is required for movie viewing. If mixed, the effect will be greatly reduced.

In general, KAISFLY is positioned as a smart speaker in the living room, an independent audio-visual hardware, rather than as a derivative of the sound bar as a TV speaker. No matter in terms of listening to or watching movies, there is no doubt that the brand sound bar within 2000-3000 seconds will be sold. The sound effect of the cinema is very outstanding, which can meet 30-40 square meters of audio-visual space, The HIFI effect can also achieve the effect of the entry-level HIFI system of 2-3000 yuan. The cost performance ratio is quite high. If you are interested in SOUND BAR products, it is better to experience this domestic SOUND BASS.
