OFweek smart home network news Early last century was the hottest era of home theater, mainland China's pursuit of audio and video pleasure is almost the most common trend, in order to meet in the living room to enjoy the same as the cinema's grand sound field and surround effect, the world's largest Dolby Laboratories, one of the audio and video technology companies, released the Dolby Pro Logic Surround Sound standard, which laid the foundation for establishing a reliable audiovisual standard for home theater.
However, the early surround systems were all wired, making it inconvenient to use either for wiring or use, and Philips released the Fidelio B5 at CES 2015 to be perfect under Dolby Surround 5.1. 8G wireless transmission technology and a number of patents became wireless surround theater systems that won the CES Innovation Award at the show. With the development of the market, Fidelio B5's promotional efforts in the current 10,000 yuan can be quite gratifying. If interested friends may wish to go to tea tea home to see more, as to the effect of how we through the actual trial for everyone to answer one by one.
Design appearance:
Philips B5, as Philips' flagship wireless surround film theater system, won positive awards for IF and gold awards. The overall use of simple Nordic style design as the main tone, selected the textile and metal wire drawing favored by the top speakers nowadays. The combination of craftsmanship. The main body contains a detachable whispering wall section and an independent wireless subwoofer. The whispering wall size is 1035X70X156 (with removable speaker) mm, the bass part is 200X510X200 mm, the whispering wall weight is 4.18kg, and the subwoofer part is 5kg.
In actual use, the author moved the B5 suit into the television in the small study. He found that the 32-inch TV does not look bloated. Instead, you will find that the design of the TV is very similar to any home and TV. Good match, of course, the subwoofer part to facilitate the shooting of the author on the desktop, we can see the body size and the 32-inch TV's volume gap. The whispering wall power is 120W, and the subwoofer part also has 90W power, which fully satisfies the power demand of the sound pressure volume of the main room.
B5 adopts a textile dust-proof net cover, which can completely reduce the bad diffraction problem of the sound compared to the general metal or plastic net cover, ensuring that the natural sense of sound is fully utilized. Under the hood, you can see that the LED dot matrix light shows the current mode status and signal access port. It will not be as clear as the general cheap whispering whispering system. The central part is made of metal wire drawing panel reinforcement structure. The use of metal power buttons is also quite attractive.
The two ends of the whispering gallery are independent unit parts. Each unit module contains a 3-inch speaker and contains a ferrofluid treble sphere. The bandwidth of the satellite speaker can reach 150-20K (-3Db) to ensure the surround sound. Has enough high frequency space to support details. With simple extraction, they can be split into wireless surround units, and the built-in battery can be seen as the charge indicator lights up when the individual unit is plugged into the echo wall.
Pull out the whispering walls on both sides. You can see the shape of the picture below. The link part includes a separate Bluetooth switch and whispering wall mode 5.8G wireless switch function, to ensure that you want to use to turn one of the speakers into a separate Bluetooth It can also be easily bound when used. The speaker's battery life is enough for you to experience multiple movies and episodes without worrying about battery life.
The disassembled whispering part will enable a set of 3-inch full-frequency and 1-inch soft dome tweeters at both ends of the interior, which highlights the timbre advantages of the center stereo part compared with the combined mode. The satellite speaker part instead highlights the high-frequency space music support part. It can be said that in terms of design ideas, Philips' audio-visual department fully considers the reasonable complementary advantages between the main center and the satellite.
Even in the author's 60-square-meter living room, the surrounding part can still feel good space support and atmosphere details on both sides of the sofa. It can be said whether the stability of the two 3-inch units or the sound pressure and sound quality of the wireless transmission. None of these are comparable to those of early wireless surround designs.
B5's wireless surround speakers can also be placed at any time through the Bluetooth connection of the mobile phone, which can meet the wireless scene requirements of various homes. You can place the independent part to set the Bluetooth mode to place songs on the balcony, or you can put another one in the kitchen. Listen while cooking. At the same time can also switch the combination of home theater, which is the development of B5 in the development of the surround with the need to adjust the 2.0 design goals, so that the theater system + music system + personal entertainment system: a multi-purpose machine to avoid a lot of people to buy A sound system can only fit one application model.
Many professional players may feel that such a system is not enough space positioning in the wireless placement of the surround process, in fact Philips for this flagship system is equipped with a lot of top-level products to have the spatial calibration function, through the simple operation of the remote control, regardless of your How can we get the best emperor bit experience.
The subwoofer part of the B5 was also a surprise to me. It used the vertical bass-long stroke column design that is rarely seen nowadays. It didn't compromise on the thin and light direction of the home to ensure the inner volume and low-frequency dive. I believe everyone can see it. Such a subwoofer part will not feel, this box will have too many limitations in the sound and design bottlenecks. The subwoofer's bandwidth is 20-150K (-3DB) Hz and the impedance is 4 ohms.
What's more, this is a wireless subwoofer that can be used without any wiring and plug-in. The rear panel can see the heat dissipation and the circuit part is properly set in the middle section. When connecting, it will automatically search for paired indicator lights to satisfy the operator. Know the current state, if no sound through the indicator can determine whether the link is normal.
The woofer of the subwoofer is also completely sloppy. The 6.5-inch woofer multi-layer diaphragm is used. The inner diaphragm has enough play on either the overhang or the stroke to match the entire cabinet. Phase tube can get enough low-frequency energy and dive.
Of course, some people doubt that such a subwoofer part will not be subject to wireless loss? In fact, compared to the previous 2.4G technology, Philips uses a 5.8GHZ wireless Bluetooth transmission set, with the unique power amplifier circuit optimization and compensation, can completely achieve the following 40HZ frequency extraction and reorganization, to ensure such a large The box has been fully utilized, rather than the short low-frequency effect of the short, small cavities like the mainstream for good-looking.
In connection with the port, B5 uses the popular 2 way HDMI input, 1 HDMI output section and then through the HDMI audio and video separation and then output signals to the TV, this can be perfectly adapted to the mainstream home network inside the digital set-top box and network box or High-definition player, no need to worry about the impact of mainstream 4K quality effects. It also comes with fiber optic input, USB upgrade port, traditional RCA input and coaxial input, and a 3.5MM AUX input, covering the port input of all new and old mainstream devices.
The operation part B5 can use a Bluetooth APP to perform pairing operations. It can also be operated using a remote controller. The remote controller includes a variety of sound modes and spatial calibration, and even separate treble and left-right equalization subdivision settings are fully satisfied. Many people are critical of the details of the set requirements. Remote control using metal wire drawing panel can also generally protect bear children from damage.
In addition, in Bluetooth mode, B5 supports the best APTX lossless audio quality on Android phones, and also supports IOS Apple phone AAC encoding. At the same time, the NFC pairing can be supported. It is located on the right side of the power operation panel. It can be seen that the small N word is where the NFC near field binding module is located.

Sound field hearing:
The sound field mode of the B5 is divided into 3.1 and 5.1 combination disassembly modes. In the 3.1 whispering gallery mode, the sound field focuses on the density and energy changes, and the sound details are more prominent for the positioning of mainstream movie scenes. . In the 5.1 mode, the sound field width is even more pronounced. Place the satellite sound box next to the listener's right and left ends and you can feel the more obvious spatial high-frequency support details. At this time, although the sound around the box is not loud, But with a one-button calibration on the remote, you can even feel the real effects of HD music and Dolby 5.1.
Thanks to the ideal low-frequency active wireless design, the fusion of the low-frequency part of the dive and the scene produces a powerful picture depiction, especially in the case of multiple explosion scenes such as biochemical crisis, the surround position of the sound details can be regarded as distinct. Strong detail expression. Although the cabinet of the wireless speaker is not large, the effect is enough to clearly feel the ideal space width and the high level of support in many harsh acoustic environment tests. This is the performance of a flagship million-land positioning product. It can be said to be quite satisfactory. Especially in the sound mode switch between music mode and movie mode, you can completely feel that the three-frequency adjustment has been more prominently played, and the sound field in the music mode has the best natural feeling. The movie mode focuses more on full impact and positioning.
Low frequency listening:
The low-frequency part of B5 is in fact diversified and adjustable, because the high and low frequencies have independent adjustments and mode switching changes. From the aspect of morphological characteristics, the low frequency of B5 has a good natural sense, unlike the general low-frequency subwoofer. Strong tone rendering, but can feel rich texture and impact after adding a few files at low frequencies, which for many people usually want to be balanced in the sound of music and movies. The design of B5 is to meet such a comprehensive demand design.
In terms of low-frequency dive, B5's dive guarantees the high efficiency of transient response and also has an ideal and powerful potential. In particular, the drum's landing and landing attenuation is sufficient for sound pressure and large room environment. Such low-frequency diffusion and The texture effect that the intensity reveals is very good, you even think this is more like the low frequency of the high-quality music sense of the bookshelf speaker, this is really the ingenious that B5 considers the choice of music and film in comprehensive design.
IF hearing:
The B5 midrange part is not as cold and stiff as the general similar system. Instead, it has done a lot of optimization on the circuit. The B5 has a very good sense of music in the midrange vocals, especially the texture and vocal depth of the midrange instruments. Have a good play. For example, the male part and the female part are not obviously biased. In particular, through the adjustment of the mid-low frequencies, it is possible to show a different timbre for different thickness perceptions.
From the basic features, B5's mid-range details are rich in docile richness and density, especially in the panel diffractive part, and there is no stiff drawback of the general whispering gallery system. Under large volume reproduction, the IF distortion is also well controlled and the vocals are pleasing. And full of emotional expression qualities. Compared to the LG wireless system and Sony's wireless system that I heard in the past, it is clear that the B5 is more like an independent 2.0 sound in the midrange to focus on quality and detail expression. At the same time, people in the movie scene dialogue, you can feel the ideal The analytical power and the scene have a good integration.
High-frequency hearing:
The high-frequency part of the B5 is not stimulating, but it also has a naturally loose timbre level in terms of brightness. Many whispering whispering systems use metal panels to gain but also produce diffractive parts. The B5 has a stronger high-frequency texture in the 3.1 combination mode, and the high-frequency space effect is more exquisite and clear in the 5.1 split mode, and both the spatial and high-frequency layer sense is shown.
This is to some extent the combination of the advantages of the two tweeters. At the same time, the high-frequency timbre changes in the wireless system appear richer and more diverse in texture. Listening to some symphony MV live classes, you will feel that the B5 design is in place. In some movie scenes, the light music of high-frequency instruments or the fast rhythm of sounds in the animation soundtrack can also be well mastered. It can be said that the high frequency of B5 is quite comprehensive with an omnivorous trend, but it is comprehensive and balanced, but it will not be too prominent and ruin the balance of the entire system. It is regarded as a fluent tone of expression and easing.
Product summary:
In recent years, wireless speaker systems and wireless headsets have made great progress in design. Thanks to structural advantages, many wireless speakers are closer to cable, and especially the explosive growth of Class D amplifiers and multiple audio fields have made B5 Advanced wireless systems can reach the average consumer's home. Regardless of the wireless design experience or sound quality, the B5 is an extremely efficient product that requires no complicated operations and wiring to achieve the high-quality audio and visual effects that most people can enjoy. What's more important is the advanced configuration features of a multi-use machine. As a flagship, the price of JD.com now is definitely a product that makes the author also excited, and this B5 home theater has a very good Physical store experience, so interested friends may wish to try the local store.
