Listening to the Real Sound: An Affordable Panoramic Sound Home Theater Speaker System

Before a series of sunburn articles were published on home theaters, the comments repeatedly mentioned why there was no sun speaker. It was very simple because the speaker system was finally set up. As a picture quality party, the picture quality party that can only tolerate sound quality (in fact, it is not enough money) has no plan to rush to upgrade the panoramic sound after the basic 5.1 system is built (one bleeding is too heavy and the money bag cannot be injured) because At present, there are not many ordinary soundtracks with panoramic soundtracks. The previous movies did not say anything. In recent years, only a small number of movies have panoramic soundtracks, and the sound of panoramic sounds has gradually increased and upgraded no later. However, after the 4K Blu-ray started, the situation is different. The newer 4K movies all have panoramic sound tracks. It can be said that the panoramic sound track has become the basic configuration of 4K Blu-ray, so that the panoramic sound becomes very Necessary, and sound effects of non-panoramic sound film can also be achieved through the power amplifier upmix function close to the original panoramic sound effect, so immediately installed the sky sound box constitutes 5.1.2 panoramic sound theater basic configuration.

The sky channel makes sound from plane to stereo, everything is for a more realistic listening experience

4K Blu-ray (UHD)

4K Blu-ray movies basically have panoramic soundtracks. Basically, they are standard. The following are all panoramic sound disks, including Dobly Atmos and DTS X.

The current panoramic Atmos is the mainstream, more than 70% of the panoramic sound films are equipped with Dolby Atmos

DTS X is still a niche, but it will slowly increase. It is still impossible to compete with Dobly Atmos.

Previous sun drying on home theater:

The basic introduction of panoramic sound has been briefly introduced in the Tiandan Power Amplifier's sun list, and there is no more description here. A panoramic sound system is a major breakthrough in the theater speaker system in recent decades, which can significantly improve the sound experience. (Personal experience) .

As mentioned earlier, it must be economically applied. It must achieve the desired effect, and it must not spend too much money. Therefore, it is my choice to buy more brands with better reputation. The first is the construction of the 5.1 system. The popularity of Jazz Klipsch in the home theater has become my first choice. The 5 in 5.1 is Jazz's new RP series. The Subwoofer has entered the SVB entry gun SB2000.

The Jayce RP series was launched to replace the previous RF series. It has made targeted improvements to the shortcomings of the RF series. It has received a relatively good evaluation in the AV199 forum and is recognized as a cost-effective alternative. The main box is selected RP260F, the center is RP450C, wraparound RP240S.

Because the subwoofer couldn't be played in the living room, it chose a 12-inch closed gun, and the sense of quality was changed. (The sense of practicality is enough.)

All of the above are sold in a physical store and the price will be cheaper than the above, and the installation and commissioning will be paid separately.

Later, when it was time to upgrade the Sky Channels, it was difficult. In principle, in addition to subwoofers thinking that all channels use the same brand of speakers as much as possible, they initially considered using Jayce's embedded speakers plus back boxes, but the price was very unfriendly and effective. Not as good as an ordinary bookshelf case, so consider bookcases, but the Jazz RP series bookshelf is also not cheap. There is no way to break this rule. Choose products with higher cost performance from other brands. The sensitivity of the volume and the human ear to the height of the sound is not as good as the sound of a flat surface. My ear cannot hear the difference in tone between different brands. I found a circle and found that the Boston Acoustics A25 met my requirements. As a US brand, we could get a 5 star rating from the English-language British authoritative magazine What HiFi. It is certainly good, and the price is less than 1500, so it is very friendly. Direct online shopping.

The appearance of Jazz's RP series speakers is a typical boxy, quite satisfactory, with a horn tweeter at the top of the black box plus an iconic gold cone.

Main box: Jayce RP260F, basic parameters (from Jess official website)

FREQUENCY RESPONSE: 34-25kHz +/- 3dB

Horn treble features high sensitivity, relatively low power requirements, and good directivity.

A 1 inch diameter titanium film horn treble plus 2 6.5 inch ceramic aluminum mid bass cones

Titanium film horn tweeter, Jazz's signature speaker assembly

It can be seen that this Jazz's horn is not a simple rectangle but is first circularly diffused and then converted into a rectangle, which is said to improve high-frequency ductility.

6.5-inch ceramic aluminum sound basin, color matching is Jazz's favorite gold

The nameplate on the back of the box

In the home: Jazz RP450C, said that the home is the center of the theater system, in fact, is basically relying on the home voice, so the most important thing is that the home voice band must meet the standard, the heavy heavy, the bright bright, The hoarse husky, not everyone speaking like a singer. It is because of the importance of the home, so choose the Jazz RP series of the flagship in the home

Basic parameters:

FREQUENCY RESPONSE:58-25kHz +/- 3dB

SENSITIVITY: 97dB @ 2.83V / 1m

POWER HANDLING (CONT/PEAK): 150W/600W

The four bass horns provide a wider sound field. Although the 5.25 inch is not large, the response is more sensitive and the intermediate frequency is more prominent. There are 4 simultaneous vocals and the bass is not too weak. The treble is still the standard 1 inch of the Jayce RP series. Titanium film horn treble.

This is how the cover is covered. The cover is magnetic and easy to pick and place.

Remove the net cover

Placed directly on the ground, underneath the pad of a pair of proud Lei with a certain angle of the mat, the picture was a bit stunned

Around the election is Jazz's RP240S, the main problem is not selected 250S budget, but I think 240S is basically enough.

Basic parameters:

FREQUENCY RESPONSE: 62-25kHz +/- 3dB

Do not look it small, light weight.

Here is to say the subwoofer, as the saying goes subwoofer is the soul of the theater, but also the number one weapon to disturb people, generally speaking subwoofer can be divided into closed and oriented, closed texture is good but the amount of sense is not as good as oriented, out of too much Perturbations also do not want the guiding ideology of bleeding into SVS's SB2000 subwoofer, 12-inch closed type, the gun body is not large, only 16 kilograms, in the subwoofer's world is basically a small point, but this cannon can also blow Blow trouser legs, press the sofa can also be obtained. 500W rated power, 1100W peak power, 19Hz dive, basically enough, after all, is not a heavy taste person.

Remove the iron cover, 12-inch unit, in order to further reduce the vibration and disturbing people under a pad, saying that this mat is quite heavy, Amazon purchased from overseas.

On the back of the subwoofer, three knobs are volume, phase and frequency

After introducing the basic 5.1 system, the following is the sky speaker. The sky speaker is the speaker whose name suggests is hung on the ceiling. The sound that produces a more real and natural sound depends on the sound from heaven. Panorama sound in home theater is also just starting, not many people use, the main reason is that the source before the film is too small, but with the explosive growth of film sources, panoramic sound will gradually spread, after all, for the overall sound effect The increase is huge. There are two main solutions for the Sky Channel. One is naturally hanging speakers in the sky and the horn is down. The most direct effect is also the best. There is also reflection. The horn is used to reflect the sound from the ceiling. Simulating the sky channel, this method is less expensive, and it is also easy to use without lifting the speaker. However, the effect is as good as the simulation of the surround sound. Previously there was a reverberation of the panoramic sound home theater, which we can refer to.

Therefore, if you are not particularly pursuing beauty, you should use sky speakers to create panoramic sound effects.

There are also several solutions in the sky speaker. There are ceiling speakers that can be used in the embedded speaker, so that they can achieve a certain balance in the effect and aesthetics, there is the embedded speaker plus the back of the box fixed to the ceiling, this way the effect ratio The former is better and looks a bit ugly. The last one is the most ugly but the best one is the ordinary speaker plus bracket lifting. Because I create a home theater in the living room, and the living room does not have a ceiling, so the first method does not have to be considered, and then because the house has lived for more than 10 years, long-term do not need to consider the value of the value of the final choice in the integrated price factor lifting bookshelf speakers The way to come as a sky speaker. Choosing the cost-effective Boston Acoustics A25 for cost considerations proved that it didn't disappoint me. It was a What-HiFi five-star recommendation.

Basic parameters:

Crossover frequency: 2,400Hz

This speaker will be introduced

In front of the map, we also saw all the open lines. The old house is good for this. It is not necessary to think too much about beauty. Practical convenience is the first consideration. The 5.1 cable is Canamei. Sky uses a Philips 300-cable speaker cable. 5.1 System It was the business who sent people to install the installation fee is not low, so when the sky speaker did not find them, this simple matter to get an electrician to get it, but did not expect to engage in a whole morning. Connected to the appropriate location of the amplifier can be debugged in the power amplifier interface, but here is more to say, each amplifier has its own gameplay, it is best to a little bit of their own tone is the most secure and not complicated, although the Odyssey is convenient but the effect is reached Not the best.

Tianlong X7200WA amplifier supports 11.2 preamp output and 9.2 post output, the rightmost is the sky channel output

The power amplifier is connected to the projection, according to the instructions to rely on their own ears to debug step by step

After debugging, take out the disc with Dolby Atmos track and DTS X track to try to light all the lights (the power amplifier decodes the corresponding track and display it on the front panel as a lighting), here to explain There is a difference between Atmos and DTS X. DTS X can turn on the lights regardless of whether you have a sky speaker and only the amplifier supports it. Atmos must have a sky speaker on the line to turn on the lights. Of course, all the lights are successful after the test. This is a must.

Here is the highlight, nonsense does not want to say more, watching a movie is a word - cool, surrounded by a sense of panoramic sound and realism is very good, better than at least 5.1 before using at least a grade, with a panoramic sound track movie Not to mention, because you can mix, panoramic sound is no longer rigidly attached to the disc with its own panoramic sound track. Some sound-good movies can also achieve better results through upmixing. The most typical movie that has been watched so far It was "The Island's Cry," and it was a startling surprise when the strange footsteps suddenly came out of the sky channel. Jazz RP series speakers need to say in their own old movies, absolutely clean and neat, magnificent, positioning is also very accurate, great sense of presence, even music that is usually considered not the strengths of Jazz can also meet My request even touched a touch. The bass sound sent by the SB2000 is good, and the sense of volume is also enough. If you really want to remove the doors and windows again, the sky speaker is equalized in three frequencies and can fully meet the requirements of the sky channel.

Say so many nonsense or look at the video to intuitively feel it, of course, home video recording with the ear to hear a big gap, especially the need to use the body to feel the bass, but also the bottom noise, but there is always more than empty white video The teeth must be strong. Finally, some Sony D100 recording pen recorded some audio, sound quality than the camera recorded stronger, but there is still a big difference from the scene, after all, is not a professional studio recording, recording format is WAV format, we can download from the network disk Listen, you'll be given a link to your web drive.

Video Camera Equipment: Sony CX900E Full HD Camera, 1080P 25P

Recording equipment: Sony D100 recording pen, recording format: WAV 192kHZ 24bit

The death knight is a built-in panoramic soundtrack, although I don't think the sound effects of this movie are better, so let's just listen to what the general effect is.
