    Wow... lets see... after crunching some numbers you can...

    Go to dinner.
    See a movie.
    read a book.
    take a nap.
    um... did I mention dinner?

    I have no idea what you are asking. Are you looking to RE-USE the box with another driver? (then why all the QTS/QES/etc) Are you looking to re-use the drivers? (Then why the box dimensions) Are you looking to improve the existing unit? (then why ANY specs)

    How about giving us a hint, or possibly a clue as to what information you expect us to provide...

    Yes, you have to figure out what the internal volume is based on the internal dimensions of the enclosure, and subtract for driver volume and anything else that is taking up space inside the box.
