    Using a 91db speaker at 1 meter,
    To my understanding (not sure if this is right) that if you put enough power for a 100db into a speaker that the sensitivity is the output, in this case 91db at 1 meter. Is this right? If so, what happens to all the lost power? where are the ineffiencies in the speakers...assuming that speaker wire loss is negligible.

    Mike,

    Your understanding is a little bit off.

    Speaker sensitivity ratings for comparison are standardized as rated at 1w (or 2.83v) at 1m.

    There is no "wasted power".

    Regards,
