Couple questions about speakers and speaker boxes

  1. Dec 9, 2009 #1
    1) Why might speaker boxes differ in shape?

    2) Why might some speakers be bigger or heavier than others?

    3) Why are speaker surfaces made of materials other than regular paper or styrofoam?

    I think you need to do a little research on your own. The things you need to think about are wavelengths and reflection or attenuation...

    This sounds like homework. What are your thoughts?

    Here's what I think;

    1) Speaker boxes differ in shape because sometimes people may want to have multiple speakers in 1 box, also the power of the speakers might be different.

    2) Some speakers might be bigger of heavier than others because they could be made of different materials.

    3) They're made of styrofoam and regular paper because they prevent sound from escaping.

    Partially correct. Check out this intro article at wikipedia.org, and see if it changes any of your answers. BTW, on the last one, I think they are asking about the actual material on the moving cone of the speaker (the part that makes the sound), not the speaker enclosure.
