Now I throw in a bunch of theory and state: in any linear system, the 
output
for a sum of two inputs is equal to the sum of the outputs for the two
individual inputs to the system. So: no intermodulation.

Now let's turn it the other way round: if intermodulation occurs, obviously
our system is nonlinear. So simply keep your system as linear as possible,
and all is (and stays) well.

And have the music always play back at low SPLs AND low spectral density.
So, no more death metal concerts and no more recorder ensembles.
