What are the criteria for a good speaker? Is the higher the power rating, the better?

Kiss Glad to answer for you: What does the rated power and maximum power of the speaker mean Answer: Kiss The maximum power refers to the loudspeaker (speaker) feeding pink noise signal in the rated frequency range The rated power of the speaker refers to the power of the speaker to work normally for a long time.

The rated power of the speaker refers to the power of the speaker to work normally for a long time. The speaker works at this power and will not be burned out. Maximum power refers to the peak power that can be achieved by an instantaneous speaker.

The speaker works at this power for a long time and can easily burn out. Because of this, it is necessary to pay attention to the power matching between the speaker and the amplifier when connecting the speaker and the power amplifier. Only when the matching is achieved, the amplifier and the speaker can work stably.

The power of the speaker is the amount of power that can be withheld, and it has nothing to do with the sound quality. It has a great relationship with the power of the power amplifier. The sound quality of the speaker is good, and the power amplifier power is high, and the power amplifier power is large, and the sound quality is good.

The power of the speaker is not as big as possible,Applicable is the best,For ordinary family users20 square meters of room,60W power in the real sense (refers to the effective output power of the speaker30W x 2)。

However, the larger the reserve power of the power amplifier, the better, preferably more than 2 times the actual output power. For example, if the speaker output is 30W, the power amplifier capacity should be greater than 60W, and for the HIFI system, the power amplifier power that drives the speaker is very large.

From the need of sound propagation distance, the greater the power, the farther it travels, and from the need of dynamic range, it is necessary to retain 12-20 decibels. Due to the above two needs, Li Lu sells the sound and learns that the greater the power of the lifting box, the better.

The choice of speaker power is related to the size of the listening area and the type of room, etc.,It has little to do with sound quality,It should be selected according to the sensitivity of the speaker、Q value and other parameters,Under normal circumstances,Defend Li rent a home 25 square meters of room speakers now 100W speaker is enough to stunner socks The amount of sound disturbance socks can be controlled within 50%,Basically no distortion can be guaranteed。

Not necessarily, it depends on what power amplifier you use, the sensitivity will be reduced when the power is large, and the thrust of the power amplifier is higher.

Not necessarily, the sound power has nothing to do with the sound quality, but with the volume, and the impedance and processor preamp have to do with the sound quality.

Summary. 1. Rated output power (RMS): RMS power can be said to be the only real meaning among all power annotation methods, which refers to the maximum power that the power amplifier circuit can continuously output within the rated distortion range.

Also known as "effective power". The power we refer to in the previous ** power amplifier circuit generally refers to the rated output power.

2. **Output power (MPO): refers to the instantaneous maximum output power of the power amplifier circuit when the distortion does not exceed the specified range.

3. Peak ** output power (PMPO): refers to the instantaneous maximum output power of the power amplifier without considering distortion at all.

The difference between the output power and the maximum peak power of a speaker.

500w is loud.

I see. Good.

Summary. Dear, hello I am glad to serve you, you can choose the speaker by the following parameters:

1. Power size - divided into rated power and peak power, the greater the power, the higher the hardware requirements, generally speaking, the greater the power of the same product, the higher the cost performance; In addition, the choice of speakers also depends on the size of the space, for example, the size of the football field is recommended to buy no less than 500W speakers, the general hotel dining hall area can be selected 100W 200W (such as ABRAMTEK E500), if the family uses 50, 60W is almost enough (such as A600); Of course, you can choose a smaller 20 30W speaker (such as A60) in the bedroom.

2. Frequency response range.

The full name is the frequency response range,The range that human hearing can reach is about20Hz-20KHz,The lower the frequency, the more it depends on20Hz means that the bass dives better,The actual speaker can't do it20Hz,You can feel the frequency of 50HzThe speaker is not considered a bass。

3. Impedance.

The impedance is usually 4 ohms, 5 ohms, 6 ohms, 8 ohms, 16 ohms; The speaker impedance is small and easy to drive, but the bass transient is easy to break and distort.

4. Distortion.

The smaller the distortion, the better, usually within 3%, and within 1% for the very high.

Choose a speaker to see the size of the quota power or the size of the peak power.

Dear, you are very happy to serve you, you can choose the speaker through the following parameters: 1, the power size - divided into rated power and peak power, the greater the power and the higher the hardware requirements, generally speaking, the same product The greater the power and the higher the cost performance; In addition, the choice of speakers also depends on the size of the space, for example, the size of the football field is recommended to buy no less than 500W speakers, the general hotel dining hall area can be selected 100W 200W (such as ABRAMTEK E500), if the family uses 50, 60W is almost enough (such as A600); Of course, you can choose a smaller 20 30W speaker (such as A60) and so on2, the full name of the frequency response range is the frequency response range, the range that human hearing can reach is about 20Hz-20KHz, the lower the frequency, the more it depends on 20Hz The better the bass dives, the actual speaker can't do it20Hz, you can feel the frequency speaker of 50Hz, even if it is not considered a bass. 3.

Hello, has the last question been answered for you? If you have any new confusion, please feel free to find me again, and I will answer it for you as soon as possible. I wish you all the best!

There are six main technical indicators: frequency response, signal-to-noise ratio, dynamic range, distortion, transient response, stereo separation, and stereo balance.

1. Frequency response.

The frequency range of audio equipment during playback and the amplitude of sound waves as a function of frequency. The frequency amplitude of 1000 Hz is used as a reference, and the frequency amplitude is expressed in decibels (dB) as a logarithm.

The overall frequency response of the sound system is theoretically required to be 20 20000Hz. In actual use, due to the circuit structure, the quality of the components and other reasons, it is often impossible to meet the requirements, but generally at least 32 18000Hz.

2. Signal-to-noise ratio.

The ratio of the sound reproduction sound of the audio source software of the audio system to the new noise generated by the whole system, the noise mainly includes thermal noise, AC noise, mechanical noise and so on. This metric is measured in decibels (dB) as the logarithmic ratio of the rated output power of the playback signal to the system noise output power when there is no signal input. The signal-to-noise ratio of the audio system should be at least 85dB.

3. Dynamic range.

The logarithm of the ratio of the maximum undistorted output power during audio system playback to the system noise output power at static time, in decibels (dB). The dynamic range of a better sound system is above 100 (dB).

4. Distortion. When the sound system replays the source signal, some parts of the original source signal (waveform, frequency, etc.) are changed. Allah in the sound system has the following types: harmonic distortion, intermodulation distortion, transient distortion.

5. Stereo separation.

Stereo separation indicates the degree of isolation between the left and right channels in a stereo system, and it actually reflects the degree to which the left and right channels crosstalk with each other. If there is a large crosstalk between the two channels, the three-dimensional effect of the reproduced sound will be reduced.

6. Stereo balance.

Stereo balance represents the difference in the gain of the left and right channels in a stereo playback system, and if it is not too balanced, the panning of the reproduced stereo will be shifted. Generally, the stereo balance of a high-quality audio system should be less than 1db.

7. DB is widely used in electronics, it is a relative unit for measuring and comparing the magnitude of power, voltage and current of a system.

Is the power of the speaker the sum of the power of all the speakers? In the same speaker, the three speakers of the high, medium and low frequencies are not simply connected in parallel, but are connected together through a crossover. Through the crossover, the treble, midrange, and bass currents flow independently through the three speakers.

Therefore, the total speaker power is the sum of the power actually obtained by the three speakers. When roughly estimating the maximum power of a speaker, you can add the maximum power of the three speakers and sum it, although this calculation is not strictly scientific--- because the three speakers usually do not reach the limit power at the same time. Hope it helps.
