Default 3-Way Driver Spacing

I have a quick question in regards to the distance between speakers. I have read that the vertical distance is a relation to the wavelength of the highest freq., I assume this is the crossover freq.?? Is this distance from center to center of the speaker?

In a TMW 3-Way, would the spacing between the woofer and the midrange be the lower crossover freq. and the spacing between the midrange and the tweeter be the upper crossover freq.?

AFAIK: the distance between the centers of two units should be at least half of the wavelength of the cross-over frequency.
But it also depends on what order filter you use. A higher order gives you a greater distance.

OK...been doing some reading.....I have seen 1/2 wavelength, 2/3 and 1 wavelength, which is it? Does each correspond to a certain type of crossover? If so, is there a website that summarizes that?

Basically, closer is better. Some people say 1/3wl actually. It's most important when using first order crossovers, to reduce comb filtering. Higher order types can get away with wider driver spacing. 'Course, they're less likely to need it... I prefer 3 ways with wideband drivers and first order crossovers myself.
