Features: brand new and high quality 4 high-temperature-resistant large inductors, which are independent and do not interfere with each other. Division of labor is clear, ensuring that each channel has an inductor, which better reflect the original taste of the sound quality.The rare switch adjusts the sinking depth of the low frequency, which is more convenient for audiophiles to flexibly adjust their sound quality. The connection method of the tweeter is to connect two tweeters in series. If only two tweeters are connected, the sound is very small. The two tweeters of each line ( group of 4 terminals) should have the same impedance. Personally, it is recommended to use 3.5~5 ohms The speaker of the same brand is more suitable, and the sound will be more perfect. Professional: this is a tweeter+mediant+ three-way KTV, stage professional speaker crossover and DIY upgrade tool which is to improve audio quality.
