| How to avoid first wavefront compression/rarefaction problem?
I was thinking about an "ideal" listening position and it didn't make theoretical sense to me, for this simple reason:
The compression of X wave might be the rarefaction of Y wave.
For example, I worked out that the compression of 63 Hz is 4.48 ft. However, 4.48 ft is also the rarefaction of 189.17 Hz.
My math:
?/4 of 63Hz = 1130 x 1/63 x 1/4 = 4.48'
3/4? of 189.17Hz = 1130 x 1/189.17 x 3/4 = 4.48'
So, if you have a true room (EQ is uniform throughout) and your speakers are 4.48ft apart and you 4.48ft away from each monitor (getting that equilateral orientation) then you will be hearing the greatest amplitude component of 63Hz and will barely hear 189.17 Hz.
Do you see my problem?
Room treatment makes no difference because I'm talking about the direct wavefront. Indeed, you could avoid the effects of unwanted peaks and nulls with the room via treatment, but this implies taking reflections into consideration. I'm not. I'm considering the first direct wavefront: there will be some frequencies that are louder than others depending on how far away you are from the source.
How do you avoid/get around this?
If my reasoning is wrong somewhere, please let me know.
