All well and good technically, Dave, but when it comes to designing a loudspeaker system, baffle step, OB rolloff, and room interaction don't confine themselves to 20-160hz!
You cranky today?
All i was doing was reiterating the standard definitions for the octave ranges. A lot of people use the terms and mean something else, it is good to have a definition. As Scott says, an actual frequency range is more difinitive.
