: : Typically, I avoid delaying things unless:
: : 1) There is a physical distance between cabinets that reproduce the same or overlapping frequency ranges and they cover the same listening area as well. The Physical distance must be such that one set of speakers is 'farther than the other set from the listening area.
: : or
: : 2) There are components in the same enclosure that are physically closer to the listener from other components and testing has shown that delaying them offers an improvement in the sound.

: If this is truly the case then what about driver alignment. I honestly thought that lower frequencies took longer to travel to the listeners ears than the higher frequencies. So then this would mean that higher frequencies really don't travel any faster than lower frequencies.
True, at least in the realm of application that we deal with. Now, low frequencies do tend to travel farther but that is not a speed issue.
Driver alignment would be covered by #2 above where one driver would be closer to the listener od measurement point than the other.
Additionally, even if lows did travel slower, you would never be able to correct for it. No matter how you set the delay, people farther away would hear it out of sync.
Sound does travel at diferent rates depending on air density, altitude, moisture etc.
