IHambrabi, in a rectangular room modes are predictable, measurable and defeatable. But to beat the modes you must have at least 2 opposing subwoofers. Ideally 4. If you dont have that option (few do!) , placing the listener at a behaved area outside of a peak or null is a must.
Floyd’s point in the powerpoint is multiple subwoofers and where -not modes dont exist or exhibit behaviour in rooms. He is saying a “golden ratio” room size (1:1.6:2.6) or similar is not a must for reproduction.
A perfect speaker, without regard for the other items first, in my opinion, guarantees nothing. Wasnt this the case for people who bought based on Olive score?
I watch all of Andrews videos too.
Great fundamental stuff.
