    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!

    Well I've learnt a bit from my first prototype.

    I need to make some improvements such as:
    - padding for the magnetic block on the back of the speaker to reduce unwanted vibrations and 'noise'
    - Improve airflow to the rear of the speaker so it doesn't create a vacuum and produce muffled audio
    - The driver bracket needs to fit the speaker more precisely to hold it more secure
    - If possible use the airflow/vent to improve bass output
    - make sure the positive and negative are soldered the right way round

    Mark I sounded pretty decent for a first try. I used the speaker components from my existing PC speaker and un-soldered them from the case they came with.

    Would anyone like to suggest where I can buy some high quality speakers with a diameter no bigger than 65mm?
    Can I buy the drivers that companies such as Pioneer, KEF or Bose use/make?
