Let ’s talk about the unit first. For common units in general audio magazines, either the brand name or the unit of a certain manufacturer is unfortunately. Unfortunately, the former usually lacks enough information, regardless of specifications. The characteristics, even the materials, are often under the circumstances that are not well understood. For a speaker commentator, what should I do? Oh, what can't be done, so I have to read a lot of articles in the world. Once someone has analyzed the advantages and disadvantages of paper and plastic diaphragms, they have to use them here and there. There is a vote for the authors. Do n’t worry, after all, this situation is not unexperienced. The wonderful thing is that over time, this statement will eventually become the truth. As a basis for some players to choose speakers, Yan Shen Yan Shen, finally this concept It will affect the hands-on audio fans. It ’s strange that it ’s really not covered, so I ’ll see some people picking the unit below, “Oh, the treble and midrange are made of different materials. . "
Again, I am willing to take the risk of being hacked by others. Anyway, I am already used to it. Talk about the famous factory unit, famous, to be honest, in the capitalist world, there is no certain advertising or marketing, and it is difficult to have this prestige. This is not a bad thing. People are doing business, not charity, let alone If the wisher ticks, that can blame others. Although these units are not cheap to buy, for some super high-end speakers, the price of making a set yourself is likely to be only one-tenth, or even one-hundredth. It must be that some people have read and reported these magazines. , I can't help but think about it. Even if I only make a few pairs, even if only one pair succeeds, it's still a good deal. This is really an interesting phenomenon. I personally believe that the horn feature of "if you know the specifications and data, you may install it yourself may be cheaper than buying off-the-shelf". It is very, very rare. It completely violates mass production and can create benefits. Everyone's theory.
Look at the speaker section again. In recent years, magazines have talked a lot about installing or changing their speakers. But sometimes I see Xuan Zhi and Xuan's saying, I am quite shocked ..... with this imagination ... admire, admire, really admire. In any case, the most commonly discussed speaker box is probably the material and shape. Alas, unfortunately, in the T / S Model, the importance of these two is far lower than the volume and reflection holes of the speaker. Does material weight matter? Of course it matters, but in terms of specifications, its importance is not whether I use piano castanets, or whether I use deadly cement, but whether there is resonance. Looking at the waterfall chart, below 200Hz, if you see the "waves" and the duration of more than 50ms, it is likely to be the contribution of speaker resonance. Generally speaking, if the resonance time is too long, it means that there are more sounds coming out for no reason, which will definitely affect the timbre. Is the word "influence" used ingeniously? Good or not? It is of course not theoretically good to come out for no reason, but some speakers are designed to use this feature very cleverly, such as LS3 / 5, JBL, Altec, Westlake, etc., to increase the energy of low frequency, no matter what, because of this work It is not easy to control, because the adjustment is equal to the need to make a lot of civil engineering, change the speaker, change the speaker box, the optical unit and the crossover are enough, why do you have more variables? So I do not recommend you to regard the resonance of the speaker as a design project you install one. How to judge whether the speaker has resonance? It ’s very simple, just tap it with your fingers and you know, this is the question that Brother Li Min used to be confused about in “Music and Soundâ€. Every time I introduce a pair of speakers for me, I ’ll go knocking on the east and knocking on the west. What is this doing? ? The easiest way to know whether the material is good or not, is to use our fingers ...... Now ... Brother Limin, do you know what you are doing?
Someone mentioned the loudspeaker box of the Chinese mall before. To be honest, I was one of the users in my early years, because the price is indeed very low, but it is not to say that these people are businessmen after all. Although their woods say MDF, but I personally do n’t sound like it. If you look closely at the interior, some parts are often made of better wood, and some are used especially thin. It is really difficult to have no speaker resonance, but in terms of price, It seems that there is no need to worry about it. In my opinion, the loudspeaker box of China Mall is considered good. After all, the price is directly proportional to the quality, but I personally found that when using LMS, many well-known units are not very good in quantity, and the specifications are not the same as the published ones. Even if there is serious fraud, for example, the T / S Parameters calculation provided by it can not be calculated at this frequency, but the measurement charts of others just reach this frequency, and bullying others do not understand the model? The package advertised as a pair, but it is not worthy to be measured at the bottom, as if we are the wrongdoers.
Seeing this, you might be a little shaken by the speaker ’s confidence? In fact, this is not my intention. I just want everyone to save some money. I do n’t have to pursue expensive units. The money should be spent where it should be. It ’s better to match, since the result of matching is the same, why buy a pair? I just want to say that the good and bad of the unit are not directly proportional to the price, and some people like to use the selected unit, everyone. The quality of the unit is really the most accurate measurement. As for the data provided by the original factory, alas, everyone listens to it and looks at it, do n’t believe it.
Then there is the part about the shape of the speaker box. Well, I personally do n’t particularly like to make a big fuss in this regard. I just want to use what has been emphasized before. Speakers should not be considered as independent individuals. From this point of view, the meaning of shape should be the interaction of space with it, not a single consideration. For example, diffraction is good. When we are in a no-noise room, diffraction is not very important. But in the home space, its importance is high, because the reverse setting will affect the sound. Well, here I personally would also like to provide a little personal experience. The asymmetry of the space is actually incredibly high. The pursuit of certain specifications, such as super straight frequency, or super precision matching, return on investment The rate is not ideal, please take a look at this point.
The last part is about the crossover. If you ask me whether to use fever components? My answer: Yes, I will, I will use fever components. Is it strange? Not at all. When I design a crossover, I personally use such components or not, and there is only one reason, that is, the measurement results. It doesn't need a fever component, it's good to measure, so what do you do with it? When I encounter a very non-linear situation, I will try to use these components and see that there is no improvement. If there is no improvement, the problem is solved, then I will take this component without hesitation. Of course, if there is improvement, I will keep it. In most cases, I use the method of addition. Of course, this refers to the part of the capacitor. As for the resistance and inductance, to be honest, the method is the same as above, and it is generally not too cautious, because it is not necessarily better. It does n’t sound very good ...
Next is the wire. Presumably, many netizens have seen the cables I use at home? From this, you can understand that it is not the kind of audio fan who uses cables casually. Does the use of wire affect the design of the speaker? My answer: Using different wires not only sounds different, but even the measurement is different. The same problem arises again, should I use a fever wire when installing my speakers? I personally have no special opinions, but I personally would n’t use it if I could achieve the desired result without using wires.
The above La Li La talked so much, it is a compilation of some personal experience, I hope to provide you with a reference for installing your own speaker, Li Min has always urged to write an article about T / S Model, which is of course no problem, but I always Feel a little bit, first figure out the basics of the speaker, and then we return to the Model. Personal experience does not mean 100% correct, I hope you can give more advice.
