Decay looks much better.
You seem to have a boost at the low end of your graph just below 65 Hz by at least 5 db. How do you
it?
Your graph starts at 55 Hz. Can you not display below that?
EDIT: Reuploaded all waterfalls so they now show 45-105dB, as I read elsewhere that was the preferred standard scale.

The antimode did a great job at my place. I combined it with manually tweaking the "standing wave control" in my pioneer receiver, thus enabling me to create a decent housecurve. The one on the graph below is 6dB, but I've ended up with a 9dB curve now. It sounds great, and the antimode removed all room modes without any hassle. Not an amazing amount of low end, but that's the limitations of the subwoofer.
This is a XTZ 10" sub and B&W 804s with 100hz x-over frequency
Sorry, I played around with the graph and obviously didn't pay too much attention to the scale when I made the screenshot. I have reuploaded them in the original post now (please refresh), they now show 20-140hz.
I have attempted to create a 6dB housecurve starting at 80hz and increasing to 6db at around 40hz as you can see from the graphs a few posts up. It sounds really good, very clean and pure bass. After I did these graphs I've increased the subwoofer another 3dB, which gave me an additional "juice" to the bass especially on older (80s and early 90s) rock recordings that is a bit lean. But it still sounds very balanced and correct. The crossover was also changed from 80hz (before) and 100hz (after).
Here's an overlay (before blue, after beige) as well

The volume change looks to be a perceived one only so not skewing the result. If you look at the dips in the response they are pretty much the same as they were when you started (obviously your boosting has brought them up marginally). The antimode has cut the peaks, which in turn will make the overall sound better/more accurate. The ringing is still there, but due to the peaks reducing they have dropped off the bottom of the scale (and out of your hearing range ). All in all response has been improved and ringing reduced. FYI, any response where the ringing is within 300ms is good, and you have a better response than many I see with almost all of it within the 300ms target, so well done antimode.
The end result is definitely better looking, and it looks
the antimode is doing its stuff. Overall response if flatter, and ringing has been reduced even with your house curve boost, result
