    Indeed. Thanks!

    Here's another bit of calculus you can do in your head:

    If "x" = the number of watts you have
    And "y" = the number of watts you need
    Solve for Y minus X

    (Hint: the solution is a positive integer.)

    interesting! 16 watts for 90db (assuming 87db speakers) at 2 meters, but 160w for 100db. Seems about right!
    90db is LOUD. 100db is so you can FEEL the sound! Very Happy
