The power amplifier is a classic TDA2030, and the results are good. If you don't have a high requirement for music, then there's not much of a problem. The power supply is recommended to be double 15V, so that the magnification can be adjusted appropriately. Here is a picture of the amplifier.

This is the PCB of the circuit, because to be debugging, it's a little bit out of shape.












The speakers were also uploaded here, and the amplifier and the speaker were not produced during the production, so there was only a physical picture.

The horn was done with a 2-inch neodymium magnetic full frequency horn, the effect is ok.

When making the speakers, I took a few pictures of cutting glass in a glass shop and a few pictures of half-finished products. Please look at the picture.
























This is my first time to do the amplifier and speaker production, although appearance is not very satisfactory, but the effect is better than the predicted one.
