音箱喇叭越大越好？
The larger the speaker, the better?
这个问题其实早就说过，不知道的小伙伴可以看看这个帖子：《家庭影院音箱越大喇叭越大效果越好》。
This question has actually been mentioned for a long time. If you don't know, you can take a look at this post: "The larger the speaker in a home theater, the better the effect.
遵循物理原则，大口径喇叭重放声音可以获得更自然深沉的低音，但是对于家用环境来说，大型音箱完全施展不开，就像你拿着一把AWM狙击枪在小巷子里和人肉搏，远不如一把轻便锋利的匕首好用。所以，适合的才是最好的。
Following the principles of physics, replaying sound from a large caliber speaker can achieve a more natural and deep bass, but for home environments, a large speaker is completely unusable, just like holding an AWM sniper gun in a small alley and fighting with people, far less effective than a light and sharp dagger. So, what is suitable is the best.
这里特别要说说低音炮，很多人会感觉喇叭越大效果就越好，越高级。但是事实上很多巨大的15寸，乃至18寸低音音箱，为了让声压更大（省钱），牺牲频响范围，重放低频都不低于40hz（重放频率越低，对功放功率大电流控制力要求也是指数级提高，成本升高），达不到家庭影院使用标准。
Here is a special mention of subwoofers, as many people feel that the larger the speaker, the better the effect, and the more advanced it is. However, in fact, many large 15 inch or even 18 inch subwoofers, in order to increase sound pressure (save money) and sacrifice frequency response range, have a playback frequency of no less than 40Hz (the lower the playback frequency, the higher the power and current control requirements of the amplifier, and the higher the cost), which cannot meet the standards for home theater use.
可见，喇叭并不是越大越好，还得看综合素质。
It can be seen that the larger the horn, the better. It also depends on the overall quality.
那么音箱上喇叭越多越好吗？
So the more speakers on the speaker, the better?
不知道你发现没有，网上售卖的LED灯并不是灯珠越多的越好，反而很多灯珠少的价格更高，而且有些灯珠多的做工很差，也并不是更亮，可能没用两天就坏了。
I don't know if you have noticed that LED lights sold online are not necessarily better with more beads. On the contrary, many lights with fewer beads have higher prices, and some lights with more beads have poor workmanship and may not be brighter. They may break down in just two days.
这就叫质不够，量来凑。
This is called insufficient quality, quantity comes together.
这是很多山寨产品的套路，就是利用了大家的心理误区。回到音箱行业也是一样，音质的好坏是由各方面综合因素决定的，喇叭单元素质箱体材质和设计分频器设计和用料，还有最重要的整体设计和调校。
This is a routine of many counterfeit products, which takes advantage of everyone's psychological misconceptions. Returning to the speaker industry, the quality of the sound is also determined by various comprehensive factors, including the quality of the speaker unit, the material and design of the box, the design and materials of the frequency divider, and most importantly, the overall design and tuning.
要做好一款音箱就像大厨炒菜，并不是香菜（喇叭）放得越多，就会越好吃，反而可能因为某种食材放多了，打破整体均衡性（喇叭单元之间干涉相位差等），导致口味（听感）变差。
To make a good speaker is like cooking a chef's dish. It's not that the more coriander (speakers) you put in, the better it will taste. Instead, it's possible that adding too many ingredients can disrupt the overall balance (interference phase difference between speaker units, etc.), leading to a decrease in taste (listening sensation).
所以老蜗牛个人认为喇叭多并不一定代表音箱就好，当然，很多高端乃至顶级的家庭影院音箱确实喇叭会比较多，成本造价也直线上升，大牌旗舰那绝对是好东西。
So personally, Snail believes that having more speakers does not necessarily mean that speakers are good. Of course, many high-end and even top-level home theater speakers do have more speakers, and the cost has also skyrocketed. The flagship of a big brand is definitely a good thing.
三分频的比二分频的好？
Is a three part frequency better than a two part frequency?
其实和上面问题的原理一样，设计和调音才是关键，本来二分频就能表现很好的音箱，非要做成三分频的话，反而可能引入新的问题（相位频响衔接等）。
In fact, just like the principle of the above problem, design and tuning are the key. A speaker that can perform well in a binary frequency may introduce new problems (such as phase frequency response connection) if it is to be made into a ternary frequency.
当然，对于高档音箱来说，肯定可以解决分频引入的问题，做成三分频就很正常了，让高中低频喇叭各司其职，表现更均衡，甚至还会有一些个性化调音功能，对抗恶劣的房间环境。
Of course, for high-end speakers, it is definitely possible to solve the problem of frequency division. It is normal to make it a triple frequency speaker, allowing high, medium, and low frequency speakers to perform their respective duties and perform more evenly. There are even some personalized tuning functions to combat harsh room environments.
音箱灵敏度越高越好？
The higher the sensitivity of the speaker, the better?
首先我们要搞清楚什么是音箱的灵敏度。通俗地说，音箱的灵敏度就是指在输入一定功率的信号后，音箱所能发出的音量大小。目前市面上的有源音箱一般以dB/W/m作为音箱灵敏度的单位，即在有源音箱的扬声器系统中输入1W的功率，在其正前方1m处测试声压的大小，从而得出音箱的灵敏度数值。一般的有源音箱灵敏度都在83dB/W/m-92dB/W/m之间，其中每相差3dB，功率就要提高一倍才能获得相同的音量。
Firstly, we need to understand what the sensitivity of a speaker is. Simply put, the sensitivity of a speaker refers to the volume that can be emitted by the speaker after inputting a certain power signal. At present, active speakers on the market generally use dB/W/m as the unit of speaker sensitivity, that is, input 1W of power into the speaker system of the active speaker, and test the sound pressure at 1m directly in front of it to obtain the sensitivity value of the speaker. The sensitivity of a typical active speaker is between 83dB/W/m-92dB/W/m, and for every 3dB difference, the power needs to be doubled to achieve the same volume.
也就是说音箱灵敏度越高，同样功率推动下发出的响度就会更大。你会发现很多舞台音箱卡拉OK音箱商用音箱基本都是灵敏度非常高，就是为了达到同样声压级，设备成本更低（大功率功放价格更贵）。
That is to say, the higher the sensitivity of the speaker, the greater the loudness produced by the same power. You will find that many stage speakers, karaoke speakers, and commercial speakers are basically very sensitive, in order to achieve the same sound pressure level and lower equipment costs (high-power amplifiers are more expensive).
落地音箱比书架式音箱好？
Are floor speakers better than bookshelf speakers?
其实这也不是绝对的，落地式家庭影院音箱套装其实是为大多数客厅环境设计的，各方面都必须妥协，比如为了放在电视柜上不遮挡电视机而缩水了的中置音箱，还有严重缩水了的环绕音箱，至于低音炮就更不用说了……
Actually, this is not absolute either. The floor standing home theater speaker set is actually designed for most living room environments, and all aspects must be compromised, such as the center speaker that has shrunk to fit on the TV cabinet without blocking the TV, the severely shrunk surround speaker, and even the subwoofer
