always said that if you can install panoramic speakers on the ceiling, the effect of home theater can be improved, but it is not easy to implement. And Focal’s Chora 826-D floor-standing speakers are directly equipped with Dolby Atmos Enabled speakers on the top, allowing you to use the configuration of traditional speakers to get a 3D stereo sound field with ceiling surround sound, and the effect is excellent, even without losing independence. The Dolby Atmos Enabled speaker is highly recommended.
Since Dolby Atmos's "object-oriented" multi-channel technology entered the home, the sound effects of home theater have entered a new realm. It can not only present sound effects above the head, but also establish a more complete 3D stereo sound field, various sound effects objects The sense of movement can also become more real and flexible. However, the practical problem is that many consumers cannot install speakers on the ceiling. In addition to difficulties in erecting and pulling cables, they will also destroy the beauty of the interior decoration after installation, which discourages many people.
Faced with this problem, Dolby Laboratories developed the Dolby Atmos Enabled speaker. Simply put, it is a set of speakers that can sound upwards and is reflected by the ceiling, allowing users to hear the upper sound with a sense of height, increasing the surround surround sense. In the past, many manufacturers have introduced this product, which can be used on the top of other speakers or on a shelf. However, it has some limitations. For example, it is best to match a specific model of speaker, otherwise the appearance will be inconsistent. In addition, these speakers must still be connected to the speaker cables independently. When placed in a high place, the speaker wiring appears messy.
directly integrates Dolby Atmos Enabled speakers
In order to meet the demand, Focal's new generation of Chora series speakers proposed a solution. The Chora series contains five products, namely the center speaker Chora Center, the bookshelf speaker Chora 806, the small floor speaker 816 and the large floor speaker 826. In addition, there is also a 826-D. This D refers to it directly Integrate Dolby Atmos speakers, hidden on top of the speakers. In other words, the 826-D allows consumers to provide the reflective sound of Dolby Atmos speakers without installing sky speakers.
Because of this approach, the appearance of the 826-D looks like an ordinary floor speaker, and the cabinet is very beautiful. The Dolby Atmos speaker used on the top of the 826-D is a 5-inch full-range unit. The diaphragm is a newly developed Slatefiber diaphragm with a special pointing angle that can make sound waves sound upward. And this group of speakers is also an independent connection port, located just above the general speaker interface, so the entire group is connected neatly without additional extension of the cable.
If you use 826-D for the left and right channels, you can enjoy the Dolby Atmos sound effect, which is similar to the effect of two ceiling speakers. If the surround channel also uses 826-D, it is equivalent to the effect of four ceiling speakers. However, if you want to use this approach, it is recommended that the indoor space be larger, so that there is a greater distance between the left and right channels and the surround speakers, in order to increase the separation of audio and video.
In other acoustic design parts, the front of the 826-D is configured with 3 channels and 4 units, and the four front units from top to bottom are: 1-inch TNF aluminum-magnesium alloy tweeter, 6.5-inch slate fiber diaphragm midrange , Two 6.5-inch slate fiber diaphragm bass. It can be seen that the slate fiber diaphragm is a very important design of the 826-D. In fact, it is also the biggest feature of the regular Chora series.
Slatefiber slate fiber diaphragm
Focal The advantage of this brand is that it has the ability to develop its own unit.Starting from the most basic diaphragm design to improve the overall speaker performance, many successful designs have been introduced in the past, such as the well-known W-cone diaphragm. The slate fiber used by Chora is a newly developed diaphragm according to its price point. It adopts a sandwich structure with a layer of carbon fiber in the center, which is arranged in a special way, and then sandwiched by thermoplastic materials to obtain better acoustics. characteristic. Although the explanation is only a few figures, in fact, there are many techniques hidden in the use of materials and how to combine them. According to Focal, it took their engineers four years to develop this diaphragm. Not only is it rigid and damping better than previous materials of the same level, but it is also lighter in weight. It is a major breakthrough in Focal's unit technology in recent years.
826-D has a bass reflex hole under the woofer, which can enhance the low frequency performance. The lower limit of the frequency response provided by the manufacturer is 48Hz. Its reflective hole faces forward, which can increase the freedom of positioning. It is OK for ordinary families to place the speakers completely against the back wall. The 826-D has a beautiful appearance, the same as the standard 826, with light wood, dark wood and all black options. Another feature of the Chora series floor-standing speakers is that the speaker cabinet will be slightly tilted after the base is added. This approach can theoretically correct the phase difference between the treble and other mid-bass to make the sound more accurate. The sound effect above
is really good
This time our review is a 5.1.2 system consisting of a full set of Chora series plus Focal Sub 600P subwoofer. The focus of the evaluation is on the upper sound effect of the 826-D, and the result is really good. In the past, we listened to the reflective sound of Dolby Atmos speakers, and some felt unclear. The ears would catch the position of the speakers instead of feeling the sound coming from the head and the sound image was blurred. Or positioning is ambiguous. Unlike the 826-D, it naturally makes people feel that the sound effects appear on the ceiling, almost above the top of the speaker, and even the eyes can naturally find the position of the image, although the solidity of the image is still not as strong as the physical one. Sky speakers, but the location of the sound effects is quite clear and the effect is very good. How can
work so well? First of all, the 826-D cabinet has a backward tilt angle after the base is installed, and its Dolby Atmos speaker is hidden inside the top of the speaker, and the front baffle will block the sound waves from the top of the speaker to the base, avoiding direct Sound interference. Furthermore, the horn on the top of the 826-D not only has a large angle towards the ceiling, but also has a partition in front of the diaphragm, which can play a similar effect as a wave guide and successfully guide sound waves to the ceiling. Together, these small details can make the 826 -D creates excellent reflective upper sound effects.
really shows a three-dimensional movie sound field
In order to confirm, I specially played some movie clips showing the ceiling sound effect. For example, in "Harry bit -Reaper's holy thing" 4KBD, there is a segment of the protagonist driving along the underground track with the dwarf. Played through this 5.1.2 system, the surrounding feeling is very good. When the car rotates When you can hear the sound effect turning around the top of the head, the sound effect on the head is very obvious, and the connection with other flat sound channels is also very good, and there will be no time for a long period of time. When the protagonist and a group of people fall to the ground, the sound effect can also be heard moving from top to bottom, and the sound effect can also create the height of the underground cave.
is also very good to listen to music
Focal has always attached importance to music, in addition to the sound effects of movies, I also want to explore the sound quality of 826-D. Playing the live recording CD of "Yellow-Lounge", the sound of the violin is gorgeous, the tone of the violin is thick, and it has some sweetness, which will not be hard. When multiple violins are played together, the positioning is clear and the sound field can be heardDepth, I feel that the picture has a sense of perspective, and the atmosphere of the entire recording scene and the audience's reaction are expressed very real and very delicate.
played Diana Krall-The Look of Love album. I found that even without the subwoofer, the 826-D still had better mid- and low-frequency thickness than I expected. It has a good sense of thickness when playing vocals. It sounds dense and thick. With a hint of sweetness. Diana Krall's labial and dental accents are clear, but not too sharp, and the accompaniment cello can also present a good sense of weight, giving a good impression of thickness, richness, and non-fuzzy overall.
A good way to get a stereo sound field:
Finally talk about my feelings. I believe that as long as there is a need to watch movies, everyone will welcome the ceiling speaker sound effect brought by Dolby Atmos, but many people cannot achieve the real environmental problems, and Focal 826-D is undoubtedly the best solution. Install speakers on the ceiling, you can get Dolby Atmos stereo sound, and the effect is very good. In addition, the Chora series uses Focal's newly developed slate fiber diaphragm, which has the potential to produce good sound when matched with Hi-End two-channel equipment. It can be said that it is comprehensive and has a wide range of applications. It is worth recommending.
