Bass trapping - corners or walls?

I've been reading articles on the ASC website and it seems that they contradict themselves regarding placement of bass traps. Most of their placement articles discusses placing bass traps in the corners. But the article below actually says that traps in corners are not that important and that traps along the mid point of opposite walls are more beneficial. What gives?
I haven't read their other articles nor do I have any direct experience with their products but what they say in this one regarding standing waves and the need for whole room treatment is true. Treating only one end of the room isn't enough. Of course this is a general statement, final determination depends on the individual space and system.

Seems most folks say that bass loves to collect in corners in which we have 12 I believe,wall/wall corners,ceiling /wall corners,floor/wall corners.
Also have heard that COVERAGE is very important and unless you have a tube trap that is 16" or bigger,I think a 2'X4' panel will out perform it.
I have experience with the ASC Tube Traps as I've been using them now for over 10 yrs. in my room. I love them & despite the fact that they do not have a high WAF I would not replace them w/ any other trap device.

I agree with Drummermitchell that bass loves the room corners where the floor-wall, wall-ceiling interfaces are. So, tube traps must be placed in the corners & yes, the diameter of the tube trap does make a diff with a 16" trap doing the best job. Pay attention to how much you absorb the mids using this round 16" tube trap. The articles give you a very good education on how-to.
Full room coverage is required so you would also need traps at the 1st reflection points & traps between the 1st reflection pt & your chair + traps behind your chair.
Panels are used to absorb mid freq & compliment a tube trap but do not replace them.
Absorbing bass is about controlling low-freq standing waves while absorbing mids is about absorbing/reflecting higher freq waves in motion. That's why you find panels a few inches off the wall & never flush with the wall. When the mid freq hits the wall, the orig wave motion stops (& uncontrolled reflections commence) & then a panel cannot do anything to that stopped wave. when the panel is off the wall you treat the wave in motion before it hits the wall to degree you desire & also control its reflection(s).
hope this makes sense.,.,,,, thanks.
