How many watts is a high power speaker, and what is the power of a general speaker?

According to the area of the room, choose the power of a reasonable size, generally speaking, a 10 square meter room with a power of 15-25 watts of speakers is enough, it can combine the sound field and dynamic range.

Completely cast.

Outdoor portable audio design should consider weight, cost, volume, usable time, etc., and the power is not large.

10-20w is more suitable.

Want a high-powered one?

There are two technologies for super audio: Developer: Yang Xiliang, Xi'an, China 18229099127 And it is full-band.

1. Magnetic field countermeasure horn technology with servo makes the horn perfect, and the main parameters of specification performance (excluding below 10kw) are as follows:

Diameter 600mm, power 10kw, sound pressure 140db, voice coil diameter 75mm, stroke 40mm, weight 50kg

Diameter 800mm, power 20kw, sound pressure 150db, voice coil diameter 100mm, stroke 50mm, weight 98kg

Diameter 1000mm, power 50kw, sound pressure 158db, voice coil diameter 125mm, stroke 60mm, weight 218kg

Diameter power 80kw, sound pressure 164dB, voice coil diameter 150mm, stroke 80mm, weight 400kg

Diameter power 125kw, sound pressure 174db, voice coil diameter 200mm, stroke 100mm, weight.

Diameter power 200kw, sound pressure 180db, voice coil diameter 250mm, stroke 100mm, weight.

Second, the super power amplifier needs two technologies:

Power tube row matrix power amplifier, 1. Power tube active voltage equalization technology, a multi-layer operational amplifier diffuser circuit, precision, high speed, with equalization output, output voltage up to 1,000 volts. 2. The active current sharing technology of the power tube unifies the discreteness of the power tube parameters through the current sharing, makes the input and output linear, and the parallel power tube of the current sharing is not limited, and the current should be as large as it is. Active voltage equalization and active current sharing form the row and column matrix circuit of the power tube, and the power should be as large as it is.

For home audio, the amplifier is 30-40W, the subwoofer is 80W, and the speaker is 20-25W.

For better speakers, the main channel output is generally between 120W and 150W.

Audio power refers to the "nominal power" of the speaker, also known as "nominal output power".

Output power"Explanation in academic literature: For other electrical appliances, nominal power, also known as nominal output power, refers to the maximum value of output power that can work for a long time under the premise that the electrical appliance is not distorted, and the maximum power refers to the maximum value of instantaneous power without damaging the electrical appliance, that is, the maximum load capacity that the electrical appliance can bear.

Output power = input power The power of useless work.

Generally, the power consumers that directly use 220 volt AC and more than 1200W are called high-power appliances to distinguish the power consumers that step down the mains power and convert it into DC. Common high-power electrical appliances in households: air conditioners, electric water heaters, ovens, induction cookers, microwave ovens, and rice cookers are not high-power electrical appliances.

When choosing a wire, you should pay more attention to choose a slightly larger cross-sectional area, so that you can withstand such a large amount of power. For example, you can choose a 4 square wire or a 6 square wire, because these two wires will be relatively powerful, and can reach between 3000 and 6000 watts.

High-power appliances.

1. Air conditioning. Because when the air conditioner is running, the power can basically reach more than 1500 watts, and the air conditioner has different specifications, such as horse, 2 horsepower or 2 horsepower. Different models of air conditioners, its power will be different, but basically it can reach more than 1500 watts, so it is a high-power electrical appliance.

2. Water heater. When the water heater is running, its load is still relatively high, basically reaching about 2 kilowatts, so when we arrange the water heater wires, we need to choose 4 square wires, and at the same time connect to the ground wire.

3. In addition, there are microwave ovens, induction cookers and ovens in the kitchen, which have relatively large power, basically reaching between 2000 watts and 3000 watts.

4. It can be seen that it is a high-power electrical appliance, including a water heater and bath bomb in the bathroom. There are mainly induction cookers, microwave ovens, ovens, integrated stoves, refrigerators, etc., while in the rooms there are mainly air conditioners, and there may be some heaters.

Consumers who directly use 220 volts alternating current and have a power greater than 1200W are called high-power appliances to distinguish those that step down the mains power and convert it into DC.

Common high-power household appliances: air conditioners, electric water heaters, electric heaters, induction cookers, microwave ovens, hair dryers.

In a home circuit, the voltage U=220V is constant. Because i=p u, the greater the total power p of the appliance, the greater the total current i in the circuit, and if the total current in the circuit exceeds the safe value, the fuse is easy to burn out. Therefore, do not use multiple high-power appliances at the same time in the home circuit.

High-power appliances are more than 1200 watts.

Direct use of 220 volts AC.

And the power of more than 1200w electrical appliances is called high-power electrical appliances. Common high-power household appliances: air conditioners, electric water heaters, electric heaters, induction cookers.

Microwave oven, hair dryer.

Rice cookers are not high-power appliances.

Usually, when we specify a device with a power of more than 1200 watts, it becomes a high-power appliance. In many places, it is necessary to pay attention to the power of electrical appliances. For example, in some college dormitories, when college students use high-power electrical appliances in the dormitory, the entire building will trip.

In life, we should also pay attention to the maintenance and maintenance of electrical appliances, which can directly extend the life of electrical appliances and avoid poor maintenance and replacement costs caused by electrical damage.

Precautions for the use of high-power electrical appliances.

1. Before use, you should calculate whether the total power of the electrical appliance exceeds when it is turned on at the same time, such as forced use will cause tripping and fuse.

Fusing. 2. Before using electrical appliances, you should carefully check whether the electrical equipment and circuits, power switches and sockets are intact and reliable, and find professionals to eliminate hidden dangers in time.

3. When using high-power electrical appliances, try to ensure that only one plug is connected to a socket, and it is not allowed to invert, rely on or cover other segments or items when using electric heaters.

4. When the personnel leave, the power switch of the heating equipment should be disconnected to prevent accidents caused by overheating of electrical appliances and ignition of surrounding items after long-term use.

5. If the electrical appliance is found to be on fire, cut off the power supply to control the fire and take decisive measures to prevent electric shock during the fire.

6. It is strictly forbidden to connect the power supply privately.

Generally, the slightly better ones are 4000 to 5000 or so power amplifiers, and the main channel output is generally 120W to 150W.

The output power of the professional audio amplifier scares you to death, I am afraid that your speaker will explode, of course, this is just a description, professional second-hand amplifier, generally a brand of 300 to 500, imported 1000 to 4000, miscellaneous new brands are only 500, we sell second-hand goods here, the United States Lescon: 1600, JBL amplifier: 700.

Don't know what grade you want? I recommend the best high-power amplifier for home use at 150W, Huiwei's good, and a little more than 4000. You'll also need to be able to match the speakers to get the best results.

If you want to buy a speaker amplifier, it is recommended to buy a set for those who are in the first acquaintance stage. Those with a high fever are generally self-serving. Sedan reeds

Summary. Generally, there are standard amplifier brands and specifications at the back of the power amplifier, and you can see the power of the power supply, that is, the power of the power amplifier. For example, 220V180W, indicating that the maximum power consumption of the amplifier is 180W

Hello, glad to answer for you

Generally, it is around 30 300w, and amplifiers over 500w are generally for professional use. It doesn't have to be a big power or a rate amplifier to meet you, it depends on how much power your speakers are, because the power configuration of the power amplifier and the speaker is fixed by Paichang; The specific standard should be: under certain impedance conditions, the power amplifier power should be greater than the loudspeaker power envy rate, but not too large.

In general applications, the non-distortion rate of the power amplifier should be about twice the rated power of the speaker; The coarse cohesion of the exciton in the large dynamic field should be about double. Refer to this standard for configuration, since it can ensure that the amplifier works in the best state, it can also ensure that the speaker's Anyan lead orange is complete.

Generally, there are standard power amplifier brands and specifications on the back of the power amplifier, and you can see the power of the power supply, and it is also the power of the power spine differential amplifier. For example, 220V180W, indicating that the maximum power consumption of the amplifier is 180W
