Corner trap myth

Can anyone comment on this please? http://www.moultonlabs.com/more/taming_the_big_wave/P1/ The Myth of Corners There is a commonly held assumption that the best place to trap bass is in the corners of a room, because there is a “bass buildup” there. Unfortunately, the bass buildup is an increase in pressure variation, not molecular velocity. If you stick a “bass trap” tightly into a corner, it can’t do much absorption at frequencies lower than those whose quarter wavelength is equal or less than the dimensions of the trapping device. For instance a trap one foot in diameter touching the walls will only absorb frequencies down to about 300 Hz.

Yes, that's mostly ridiculous. :? The proof that bass traps straddling corners improve the response is all over the internet. But even when placed flat in the walls near corners, bass traps make a huge improvement. The graphs below show the Before / After response and ringing etc in the bedroom size space I used for my Hearing is Believing video. --Ethan

Thanks. That is a great video too.
