Ok to keep it short and snappy. for my product design A2 course I'm fitting removable speakers into my product. I wanted to research and test the best way to build the case to mount the speakers in. The case should be 80x80x80mm on the exterior. On my PC speakers they have an insulative material behind the speaker and then a sort of tunnel from the back of the speaker to the front which I can only presume boosts the bass. Any advice on the internal shape, the materials and stuff? Also what would be a good way to test the actual output apart from sound? Record and analyze the output of the speaker with different cases and materials? any help appreciated!
