How should a novice DIY a set of sound with good sound quality? Any suggestions to share?

In order to make a set of sound with good sound quality, the production of the speaker should meet the design value, the ratio of length, width and height of the speaker should not be an integer multiple, and the overall aesthetic feeling of the box should also be considered. Best to use? Double line? To link audio lines, which can reduce the crosstalk between audio, bass and treble, and make the performance of audio obviously better than that of traditional single-line connection. It is a relatively detailed and complicated process to DIY a set of sound with good sound quality, which requires care and patience. Personally, if a novice wants to DIY a set of speakers with good sound quality, he must first make a comprehensive copy of his DIY. Moreover, it is necessary to choose the appropriate speaker unit diameter and understand the specifications of the equipment. The material of the speaker should be high-quality and high-density logs, and the box of the audio should be granite, so as to better make the audio present high-quality sound quality.

In DIY audio, in order to ensure the sealing of the box, the seams on both sides of the box must be cut neatly during the production process so as not to expose glue. If you are facing a wedge bayonet, you should stick it firmly with glue and nails. Foam with better sound insulation effect should be used when filling sound insulation materials. When installing the frequency divider on the stereo, if asphalt board is used, it should be installed with screws and insulating pads, which should be tight enough to prevent vibration when coupled to the box, thus reducing interference. The connecting wire in the box must be made of high-quality oxygen-free copper wire, which should be kept at a suitable length and fixed, so that the sound will not shake.

The speaker unit of the stereo should be installed by deep excavation, and the vibration during transmission should be isolated by rubber gasket. When fixing parts and junction box with screws, it is suggested to drill holes in the box in advance, so that the installed sound is more convenient and beautiful. Pay attention to the correct connection of the frequency divider when wiring the stereo system. When welding audio, use high-quality silver-containing tin, not virtual welding. Finally, the surface of the speaker can be covered with PVC or painted.
