Sean, the equation I've mentioned is not as simple and yes, this equation is being used to specify the speaker impedance curve in responce to any particular freequency. The reactance is a directional part of an overall impedance and resulting vector of reactance can be negative and that's when the impedance falls can occur.
Indeed the music is a complex signal having lots of harmonics and subharmonics but it's more arithmetics still since the numbers we work here with is finite and can be calculated. The theory states that the signal of any arbitrary form or complexity can be represented by the sum of sine waves of different order(Fourier theorem) which means that the freequency(to be more precise a sinusoidal freequency components) of an arbitrary form signal can be defined using Fourier theorem.
As to your statement about the differences in sound with relatively same capabilities amps and the speakers first of all they're assume will be not too much audiable, second there is a specific formula but truly it doesn't make a sence to excersise it untill you find the family of infinitessimal values specifying these nano-ohms and nano-volts once again using a Fourier theorem along with Ohm's law.
As to the good amp formula so not to be so exhausted calculating limits using a complexed engineering formulas(certainly applied in more sophisticated amplifiers than audio) you're completely right and I believe that Plinius SA100 falls in this category.
