I am building a birch ported box and after watching some YouTube videos one particular builder quickly says that he treats the inside of the sub box but he doesn’t say with what. Can I treat the inside of the box with clear polycrylic? Will it affect the sound or is it completely unnecessary to treat the inside of the box. I am going to stain the outside but I’m just wondering about the inside.
