Magnepans don't magically solve bass nodes unfortunately, however, adding a couple more subwoofers, some electronics for integration, and playing with speaker placement may. That may get your lowest nodes under control, and then you can work on the higher ones. If the misses is into decoration, involve her in the selection process for acoustic treatment.

Going to guess your main room is about 8m * 5m with 3m ceilings?
Then I am going to guess there is a wide hallway or extension off the main room?
8m, 5m, 3m are your 60, 110, and 180Hz approx peaks, then with a range of harmonics off those sizes.
The 45Hz is typically too low for a typical sized apartment, especially in NY and you said it is small? That leads me to believe there is a hallway / extension off the main room creating the 45Hz node and the suck-out just above it.
erik_squires10,600 posts02-22-2021 10:33amI just looked at your waterfall. That's not your speakers!
Bang on erik. It is pretty evident in the waterfall where the 120Hz does not decay. Most 60Hz noise presents as 120Hz due to rectification. It is likely electrical noise.
hudsonhawk OP113 posts02-23-2021 9:38pm@speakermaster Great question and a detail I forgot to mention is that i did decouple the speakers by adding Isoacoustics Gaia feet to the speakers. It didn’t make as big of a difference for the bass as I was hoping (although in retrospect I wish I’d measured before and after, I didn’t yet have the measurement mic) but it did improve the imaging significantly.
In terms of measurable differences, this is unlikely to make any difference. Their may be a slight slight difference, but the vast majority of the energy is coming out as sound, not vibration in the cabinet, especially something as solid as what you are using.
