I dont know much about Sound Displacement

i want to make a 15" Cube Sub
4 sided
every side a 15" sub
im willing to put the port holes needed - and willing to put the needed space inside - my main question is - how much space is needed inside the woofers are not to big
15" 2.5"voice coil 50oz magnets im guessing ill get 100 watts rms per speaker

does any body understand how much space i need ?
This doesn't belong in Advanced Techniques.

You might want to try the guitar building and customizing forum, but then that's guitar building, and not an amp.
