The most common stage power is 1000 watt rated power to 1000 watt rated power peak is 20000 watt to 200000 watt, and the rated power of home KTV is generally less than 2 * 3000 watt. Generally, the matching of front speakers for stage conversion is 2 pairs of 8 65,438+025 cores, 65,438+08 inches and 33 inches of heavy bottom sonic boom. 20-40 full-screen woofers with 75 cores from 10 inch to 100 core, tweeters with 75 cores from 10 to 20 cores from 100 core, and tweeters with 75 cores from 10 to 20 cores from below. The collocation of these speakers is mainly sound. These are the advantages of the professional stage. Remember that professional stage speakers don't use pure alto speakers under 8 inches, but they are all rubbish stage front speakers, because the maximum rated power of 8-inch pure alto speakers is 150 watts, which is small, sensitive and useless. Generally, it is best to use two to eight 75-core 100-core tweeters, and two to eight pure midrange loudspeakers with low-intermediate frequency tweeters in a family KTV. If you use a treble with more than 75 cores, you don't need to use a pure alto speaker, because the treble with more than 75 cores has covered a large number of small alto speakers, and you can't hear the pure alto sound. There are two to eight woofers below 100 core, and it is better to add one to four speakers for 18 inch and 125 core. These collocations are already the best configuration for home KTV. After watching these games, you will know the difference between the stage and the home court and so on. I don't think it is necessary to do 2.0*2. 1*5. 1 channel. If you are a few meters away, it sounds like 1.0 stereo. If you have multiple speakers, it looks elegant and the sound is the same. That is, there are 2 to 4 pure midrange speakers below 8 inches, and 2 to 8 tweeters below 100 core, so there is no need to use anti-listening speakers. Because it is near listening, you can also use 2 to 8 100-core midrange full-range speakers and 18-inch speakers from sonic boom. The rated power band of power amplifier 4*2350 is the best, which can be 2.0*2. 1*5. 1. Another small stage. You can play whatever you want in a word. It's very cool. If you can't use stage speakers as home KTV, these people's enjoyment ability is in the 1980 s, not modern enjoyment ability. The modern horn is already a high-quality horn list. This is the only speaker in China that produces high quality speakers. Full-frequency high-power Nd: 100 core 600W stage wedding performance speaker ring 8 Euros. In Guangzhou, the manufacturer, some people say that this kind of speaker is not resistant to high temperature demagnetization, and the stone magnet demagnetizes when it is hot. If the temperature of the stone speaker and the Nd: magnetic speaker is 200 Nd: magnetic speaker is degaussed, the stone speaker will also be degaussed. Not only demagnetization will first cause the voice coil to catch fire and the speaker body to be scrapped. Don't compare the neodymium magnetic horn of the 1980s with the modern neodymium magnetic horn. Neodymium magnetic copper coils in the motors of modern electric vehicles are burnt out. Why is the neodymium magnetic field in the motor still not demagnetized? Who will answer my question professionally?

Others say that the power amplifier and the loudspeaker match more than 1.5 times the loudspeaker power, which means they sell the false power of the amplifier. When the power amplifier works to 70%, both are in a distorted state, as is everything that can transmit energy. The power amplifier is greater than 1.5 times of the speaker power, and the speaker is distorted when it is turned on to 50%. How can it be true?
