In recent years, audio giants including Pioneer and Yamaha have launched their own audio products, and TV manufacturers have always been more than capable. Perhaps from the perspective of appearance and appearance, the products produced by those TV manufacturers can co-exist with TV sets, but if they are examined from the perspective of sound effects, they may not be the best choice.
However, the emergence of LG LAS751M broke this situation, and the product can compete with competitors' products in terms of sound quality. In addition, the price of this product is usually provided with Bluetooth support, but LG also added additional Wi-Fi and streaming capabilities, making it a member of the company's Music Flow product line.
The LAS751M has an excellent sound base width and can handle both music and movie tracks. This type of product basically requires a tradeoff in size. In addition, in terms of tone, the product is slightly cold.
The suggested retail price of LAS751M is 399 US dollars (about 2536 yuan), will face the same price of products such as Vizio SB4051-C0 or Yamaha YAS-203 competition, the specific choice depends on the user's demand is focused on surround sound playback or music Play some. Yamaha undoubtedly has the most outstanding sound quality in the above three products, but the LAS751M can work with LG's other multi-room streaming systems.
design
The appearance of a traditional home theater amplifier design for a period of twenty years, a black box route that has always taken place, is that the other components of the system are increasingly changing. The style change of the strip sound is particularly prominent in this area. It has an arc design, All kinds of appearances, such as wooden chassis and aluminum material, are full of fashion sense. Taking into account his own deadly Samsung's dazzling performance in product design, LG has also made great efforts, hoping to take a step ahead of the LAS 751M in the sound bar.
With its 42-inch width, the LAS751M can be paired perfectly with 46-inch and larger TVs. The front of the product is slightly taller, and gradually narrows in height as it extends backwards. The sides are rounded with metal edging, the top is covered with metal material, the front is gridded, and the blue LED lights show various status information. This design combination is both classic and clear and easy to understand.
The wireless low-frequency speakers in the accessory products also use a metal grid design. Although there are no bar-shaped sounds so eye-catching, but in most home space display will not be unexpected.
The remote control's small size and excellent ergonomic design makes it easy to find most common functions.
Features
The LAS751M is a 4.1 channel (stereo analog surround) bar audio product with 40W per channel and 200W wireless subwoofer.
In appearance, the LAS751M is similar to other audio products, but it has a lot of interesting wireless technology inside. The first thing worth mentioning is LG's Music Flow, which is a multi-room music playback system developed by the company using proprietary technology to support streaming music from cloud services, smart phones or other media sources.
Since the product does not have an on-screen menu function, the user largely needs the help of the Music Flow application to complete the setting work, including the choice of music mode (music, theater, general, etc.).
One of the practical functions provided by this system is to enable users to listen to their favorite music on a smartphone, just by using an application, and to play music on a multi-room system after returning home. Although other bar sounds can also achieve similar functions through Bluetooth connectivity, they have a certain gap in sound quality compared to LG's.
In addition, this product can be used with a pair of wireless surround speakers Music Flow H3, each H3 is priced at 140 US dollars (890 yuan). As a result, the budget of the entire system will exceed 600 US dollars (3813 yuan).
LG's system also supports Google Cast, which can be used with streaming applications including Pandora, Google Play Music, and NPR. For Spotify users, LG's Spotify Connect feature allows users to easily stream song collections.
In addition to these features that utilize Wi-Fi connectivity, the product also supports Bluetooth connectivity to mobile phones.
Wired connections include HDMI input and output ports, fiber optics, and 3.5mm input jacks. In terms of movies, the product supports Digital Dolby and DTS decoding, while music is compatible with FLAC lossless and WAV waveform files.
performance
The performance of the LAS751M strip sound with low frequency speakers was unexpected. LG engineers didn't know what skills they used, making the appearance of a slim, two-channel sound that was large, wide and deep enough to echo across the room.
When the testers used the Mad Max: Brutal Road Blu-ray disc audition, the presence of the staff all felt the speed of the vehicle across the desert. Low-frequency speakers can not be ignored, low engine roar for the performance of the entire strip sound a lot of color.
If you compare the LAS751M with the Yamaha YAS-203, you will find that the latter's maximum volume is slightly higher than the former, which is more suitable for films like Mad Max4. However, if you compare carefully, you will find that the LAS751M is superior in terms of dialogue and overall clarity.
Speaking of clarity, the testers selected a scene in the second season of the House of Cards. When Francis Underwood met Zoe Barnes on the subway platform, a drummer was performing at the other end, and the LAS751M perfectly reproduced. The sense of vibration of the drums, the metal friction of the train wheels, and the effect of these sounds echoing above the open platform.
For music playback, YAS-203 and LAS751M are inseparable.
The performance of the woofer with bass speakers was impressive, but the surround sound performance after pairing with the H3 speakers was disappointing. One of the reasons is that the system can decode DTS and Dolby surround soundtracks. Even if it is played on a CD, the device will automatically convert the signal to an analog surround sound mode. This will cause the music playback to be extremely unbearable. s consequence.
Second, the application does not provide volume control for specific speakers, nor does it have a calibration procedure. The user only constantly tries to find the best volume, and the overall effect does not seem to be consistent when playing a movie. And if you do not pair with the surround speakers, the overall effect is much better.
advantage
LG LAS751M Strip Audio with Low Frequency Speakers provides users with value-for-money sound quality. The overall background sound has a sense of space. It is full of bass, clear dialogue, and can work with the company's multi-room playback system, through the Wi-Fi string. Stream music, Google Cast compatible, Sportify Connect and Bluetooth connectivity. The product's slim appearance makes it fashionable and unobtrusive.
Shortcomings
The timbre lacks a warm feeling and is rather cold and cool. Although it is possible to work cooperatively with the surround speakers via wireless, the actual results are poor.
in conclusion
For a set of products targeted at mid-range home theater systems, the LG LAS751M performs well overall and maintains timbre transparency at higher volume levels. Although the Yamaha YAS-203 is better in some respects, the LG LAS751M is still an ideal choice for overall performance.
