What material is stereo made of?

It's complicated to make a speaker. If you can make a good speaker, with a speaker and a frequency divider, those big factories will close down.

However, some efforts can still make it sound good in your spare time.

The simplest method is to measure the size and data of the speaker unit according to a set of good speakers and draw a ladle. If you don't sell it, no one will ask you about intellectual property rights, hehe.

As for the plate, it should be stable and can restrain the vibration of the box to a certain extent. High-density compression board, decorative wood board and composite bamboo board can be used, and a layer of vibration-making glue can be added inside and sound-absorbing cotton can be attached.

Choose a good speaker unit. At the same price, the performance of the paper basin is not bad. If you are looking for beauty, you can use a composite basin.

Choose the frequency divider according to the situation of the horn, and pay attention to the selection of the frequency dividing point to match the horn.

A good power amplifier module is essential.

A stable and powerful power supply is also important.
