Subject: Max amplitude of Mac IIcx speaker

I am trying to replicate some acoustical laboratory studies on my Mac IIcx.
The sounds that I am trying to replicate range widely in frequency and
amplitude.  Frequency is no problem but the amplitudes are measured in
decibels (dB).  I know that the dynamic range of the speaker is 48 dB, but
I don't know what absolute dBs my speaker can produce.  Can anyone provide me
this information or a reference where I could find the information? 

Thanks.
