The larger the speaker, the better?
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.
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.
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.
It can be seen that the larger the horn, the better. It also depends on the overall quality.
So the more speakers on the speaker, the better?
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.
This is called insufficient quality, quantity comes together.
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.
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).
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.
Is a three part frequency better than a two part frequency?
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.
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.
The higher the sensitivity of the speaker, the better?
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.
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).
Are floor speakers better than bookshelf speakers?
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
