@oldhvymec If you watch a bit more of the video, you'll see he's not suggesting such a simplistic solution. He's pointing to a fact about acoustics which, combine with a variety of other techniques -- in some rooms, not all -- can help mitigate problems, and not just at 50hz. So, your off the cuff response while amusing kind of turns him into a simpleton. Not really fair, but hey, this is a just a forum so I guess mere joking is kosher!
Bass management -- the trick of putting absorbers at a front null
Very interesting discussion with Anthony Grimani. He advocates both traps and multiple subs and goes through the basics and tactics of bass management.
What's of interest to me is a "trick" he mentions -- putting an absorber panel at null between the listening position and the front wall. This, he says, can help even out the bass and take the place of the brute (and impractical) physics of trying to absorb the standing wave with absurdly thick absorbers.
He mentions it very soon after this point (which provides some context): https://youtu.be/QYpAbv7gKrs?t=1853
Has anyone tried this? Any details or outcomes you can share will be welcome.
P.S. He mentions Todd Welti, who did a Ph.D. thesis on using multiple subs. He's now with Harman. There is a paper by Welti, here: "Low-Frequency Optimization Using Multiple Subwoofers" https://www.semanticscholar.org/paper/Low-Frequency-Optimization-Using-Multiple-Welti-Devantier/00da...
This looks interesting, too: "How Many Subwoofers are Enough"
