What is a warm sound and why would you ever want it?
From what I've been able to determine it seems pure sound is often though of as being too clinal so it's important to add some warmth, which seems to suggests a warm sound is modified or contaminated.
If certain frequencies are considered too harsh then it likely to be an issue with the equipment and a so called warm sound is never going to be the answer.
As a side note: Audyssey can set incorrect speaker distances in an attempt to fix room issues, but in doing so inadvertently creates a harsh sound. Even a tape measure can be inaccurate, so a laser measurement is worthwhile investment.
