Whilst I totally appreciate what you're saying, I don't expect this to be the case for long. DSP technology and digital amps have come on in leaps and bounds. We're now starting to see the introduction of DSP control for individual drivers, dynamically altering the frequency response depending on speaker load etc. Whilst at the moment this technology is still in the realms of the high end, like all things it will start to trickle down to the more affordable range in time. There's some seriously cool stuff on the way for speakers.
