Notes for the First Use of Newly Purchased Speakers Cookers, cookers are like running-in periods for new items. Only after fully running-in, can the speakers bring their potential into full play. As the important part of the speaker is the key component to determine the sound quality and service life of the speaker, and the speaker is mostly composed of reinforced carton or bullet-proof cloth, the new speaker is generally more rigid and needs softening process, so the speaker needs to be cooked for a while to be better and more durable. Many people find that speakers need to be cooked for some time to sound better. We agree. The difference is that some people advocate loud talking. That's not right. In fact, the running-in between the speaker and the car is a truth. Slowly running-in will make the mechanical part (the vibration part is equivalent to the mechanical part) run-in better. It will not do any good to the speaker. If the speaker is not cooked properly, the voice coil may be deformed. Therefore, slow stew with gentle fire has a taste, otherwise it is prone to sharp voice, hoarseness, cracking, imbalance and other issues. As for the specific method of cooker, please go online to search for relevant knowledge, not to mention here.

Notes for the First Use of Newly Purchased Speakers
Cookers, cookers are like running-in periods for new items. Only after fully running-in, can the speakers bring their potential into full play. As the important part of the speaker is the key component to determine the sound quality and service life of the speaker, and the speaker is mostly composed of reinforced carton or bullet-proof cloth, the new speaker is generally more rigid and needs softening process, so the speaker needs to be cooked for a while to be better and more durable. Many people find that speakers need to be cooked for some time to sound better. We agree. The difference is that some people advocate loud talking. That's not right.
In fact, the running-in between the speaker and the car is a truth. Slowly running-in will make the mechanical part (the vibration part is equivalent to the mechanical part) run-in better. It will not do any good to the speaker. If the speaker is not cooked properly, the voice coil may be deformed. Therefore, slow stew with gentle fire has a taste, otherwise it is prone to sharp voice, hoarseness, cracking, imbalance and other issues.

2. Preventing sudden impact of large signal
Generally, there are the following situations:
One is that the switch of the potentiometer after the last audition was not switched low or someone else misoperated the potentiometer, and when the sound was turned on, it was in a high volume state, causing a large signal impact.
Second, there are sudden big dynamic segments in music. In order to emphasize contrast, most of these fragments have weak signals before the big dynamic arrives. At this time, if you don't have the thought to prepare, turn up the volume, the big dynamic signal will easily break the horn. Such as explosions, drums, thunder and so on.
The third situation is that when the sound is working normally, the signal line and power line are suddenly dialed and inserted, which will produce a large current impact, and the speaker will be most vulnerable to damage.
3. Avoid use in harsh environments
Various parts of the speaker, such as wood, paper speaker, treble film, suspension, centering bracket, adhesive, voice coil and so on, are mostly sensitive to the change of temperature and humidity.
Too low or too high temperature will affect the stability of these components. If the temperature is too low to be less than 5 degrees Celsius, the suspension edge will become brittle easily. At this time, if the volume is high, it will easily cause the suspension edge to rupture. If the temperature is too high than 40 degrees Celsius, the voice coil is too hot, which will cause sound deterioration. So speakers should be avoided in sunlight, near the radiator and below zero temperature. Humidity also has a great impact. If it is too dry, the wood outside the speaker will burst, and the thick wood box is prone to cracks. The solution is to buy a humidifier or drain a basin of clean water indoors. If the humidity is too high, the sound basin is easy to be damp and mildewed, the sound is weak, and the wiring is easy to oxidize. The solution is to put some dehumidifier and desiccant in the room.
In addition, the speaker dust and clean is also very important. When you do not listen to the speaker, it is better to add a dust cover. The speaker surface can be cleaned with a towel dipped in warm water and then wiped, but you must remember that the water is completely dry before starting the machine.

4. Pay attention to standardized operation in peacetime
When listening to the sound, first check whether the connection is correct and the potentiometer position is too large. When switching on, switching off, restarting and other operations, the speaker volume should be kept to a minimum or the power supply should be turned off to prevent damage to the speaker caused by large impulse current. When singing karaoke, keep away from the speaker as far as possible, and the microphone should not point to the speaker, so as to avoid screaming or even burning the treble unit. At the same time, in order to protect the speaker, in general applications, the volume of the speaker should not be too large, as long as enough, about 1/2 can be used, because in addition to the problem of sound distortion, some large dynamic fever discs are speaker killers. Active speakers on the market, although the nominal power is very large (even exaggerated to hundreds of W), but that is not the actual power, usually tens of W even big.
Therefore, in use, do not work at a large volume for a long time, otherwise it is easy to damage the power supply and amplification circuit. Bookshelf speakers should prevent accidental collision and fall from the scaffold. It is better to stick several pieces of double-sided glue on the bottom of the box.  When the speaker is used for a period of time, the connection ends of the speaker wires will be oxidized more or less. This oxide film will greatly affect the contact state, thus reducing the sound quality. Users should apply cleaner to clean the contact points in order to maintain a better connection state.
V. The Use of Places
Any sound will break when it's louder, so it's almost as good as 8. The power of this sound is 40W. If you use it in 100 square meters, it's more than enough. If you put it on the square or use it in a big classroom, it's bound to be unbearable.
6. Exquisite placement
First of all, the speaker should be placed in a position to avoid direct sunlight exposure, and it is not suitable to place the speaker beside the heater and where the temperature is too low. Otherwise, it will cause blistering on the surface of the speaker or aging of electrical components, and do not place the speaker in a humid place for a long time, so as to avoid rusting or mildewing of the voice coil. In addition, don't put the speaker too close to the CRT monitor. Because CRT monitors are too delicate, even anti-magnetic horns will also have a certain impact on the monitors. Similarly, the speaker should be far away from the strong magnetic field. If the mobile phone is near the speaker, the speaker will be noisy when calling.
Secondly, in order to save space, we usually put the speakers under the computer desk or stacked together, which is very unscientific. Even if it is a high-quality sound card and high-quality speakers, in this case, it will not have good sound performance, let alone live sound localization. The correct method should be: display as the center of left and right symmetrical display (take ordinary 2.1 speaker as an example). It ensures that the speaker speaker is facing the user. The subwoofer has a flexible position because of its poor directivity. For loudspeakers with large volume, it is better to use the floor bracket. Do not put the speaker directly on the computer desk (especially the subwoofer), so as to avoid the distortion caused by resonance with the computer desk.
