Nrchy,
You wrote earlier today: "What are the speakers going to add to the music that was not retrieved from the source or translated to the speakers? I just don't get it."
Are you playing Devil's Advocate and trying to stir the pot, or do you REALLY "just don't get it."? As Unsound explained, speakers commit both sins of omission and sins of commission. A sin of omission is a "forgivable" transgression. For example a speaker may do a credible, or even an outstanding job reproducing the midrange and the top end as well as the mid-bass but may have no information under, say 50 Hz. On the other hand a speaker may "add" colorations and distortions which make it difficult to tell the difference between a guitar and a dobro, a guitar and a lute, a violin and a viola, etc. A speaker may be "tilted up" in the upper midrange and present an aggravating, ultimately unlistenable signal which causes listener fatigue.
I trust that you mispoke yourself when using the phrase/concept of what does a speaker add. It implies that the upstream components ADD something to the signal. (And that ADDING someting to the signal is a good thing!) The designer's goal and the music lovers bliss is a component that does NOT add ANYTHING to the signal. A component that reproduces the original source with sufficient accuracy to look good on a graph and, more importantly, to "suspend disbelief" of the music lover and transport music lover......to the music is what we look for.
