Clever membrane based stuff can cut the size down fairly dramatically but yeah it’s still not ideal home stuff. From a music recording/mixing perspective I think these dsp things are interesting when applied to headphones to emulate spaces or different speakers but fairly useless for speakers without room treatment. Changing the amount of a frequency doesn’t change the room modes and the temporal and listening location issues they cause.

At the risk of repeating myself, you can model a room in REW. Changing the absorption properties for all surfaces. I was surprised that the 50hz hump is near impossible to loose without changing the dimensions of the room. Another interesting fact about 50hz is the size of a bass trap that would be required to attenuate it, it's massive. DSP or EQ seems to be the way to go with stuff under 100hz.
What can make a big difference in the upper ranges is the absorption of the rear wall and front wall.
