Conclusions labeled "Best configurations are" (with the green background).
I can read, its my collage lol! I've been over the results, I'm not talking top three.... I am talking number one performer....
I have seen the same study many times
Well take a look at it now, there isn't a response better than
They didn't even include this positioning in the rest of the charts because there's no competition. Below is 11, which is a better performer than 10 and 12, If you think the 1/4 corner placement is 10 or 12 you are mistaken. 11 outperforms 10 and 12 and needs more than1 band of filtering, while they state 1/4 corner placement only needed one filter below 80hzZ
vs
The only time corners are great is when you can do all corners and apply a lot of EQ
This is untrue as well, If you just do one or 2 at 1/4 distance nearest wall span, you still will get a great FR... The major null from the nearest wall is cancelled in this position. I have one sub placed like this currently
"This configuration should result in cancellation of all odd order axial modes, and the cancellation of the first even order axial mode (where the subwoofers are at a null). This can be verified by looking at generalized standing wave plots like those on pages 17-21. Note that floor/ceiling axial modes would not be cancelled, however these modes are much less important. Floor/ceiling axial modes do not cause variation in frequency response over the seating are, assuming ear height does not vary.a virtually flat and uniform set of frequency responses could be achieved with 1 band of parametric equalization! Subwoofers (4) at 1/4 of room dimensions In this case, rule of thumb subwoofer placement worked well."
This is just one sub that is sorta kinda near 1/4 spacing on the width, can't do front to rear because the basement is 30 plus feet long lol. Looking at my phase I should be able to clean all of that up with eq and the resonant at ~58hz, I mean, it'll look better after EQ but this is pretty good if you ask me. The glitch near 60hz is predictable to the chart actually... once again, just one sub.
