Driver quality vs. audio processing
Something that occurred to me some time ago but I never got around to asking about it. If I were to take two drivers (speakers here, not software) that were SIMILAR in size but not in specifications or price and hooked them both up to audio analyzers to equalize everything, what would the difference be (aside from more work depending on the amount of correction needed)?
To wit: I take two speakers, one a cheap Pyle and another a... I don't know... Focal Utopia Be. Lets say that the Focal unit has a basically flat frequency curve and the Pyle unit has poor sensitivity on lower frequencies than suddenly jumps up and back down and all over the place like the mountains of Chile. If the sound output was analyzed and the signal in turn adjusted to flatten out the produced sound's frequency curve - then what else could be different about the sound the listener hears? Mind you, I have sold high end audio equipment (think PSB, Bowers-Wilkins, McIntosh and the like) but selling is different from DESIGNING.
SO - aside from how "tight" the speaker can respond, what other variables might affect the sound quality IF the frequency response curve and volume levels were equalized through analysis and processing?
FOR THE RECORD, this is mostly a hypothetical. I don't need to be told that a "good" speaker will be "better" I want to hear reasons WHY that should be.
