Put a low pass filter before your speakers.  That is find out what is
the highest frequency of your speaker, then design a low pass filter
that does not let higher frequencies damage your speaker, at the same
pass all the lower frequencies unaffected.

                      With highest regards,
                           Babak   Sehari.
