If want hifi, open as many windows and doors as possible.

Chk this measurement difference, small room, 1 door, open (dark line) vs closed.

There was no getting rid of that via DSP.

Pretty wild difference there! I don't know a ton about WiFi, but when we had our newest router installed the technician told us that putting it up on the 2nd floor would help it work better. Since the signal supposedly goes up & falls back down like if you held a hose straight up in the air. Can't say for sure how much truth there is to that, but I will say since we did follow his advice & put it on the 2nd floor we get a pretty good signal all across the house. Although in the furthest rooms from the router I have noticed the signal being much weaker when the door to those rooms is closed.

Hifi and WiFi are slightly different. 

@tp4tissue, multiple subs throughout the room may resolve your issue without opening doors or windows. 

Open Baffle woofer/subs will excite less room nodes as well.

Red=Open
Blue=Closed
That would have been easier for all. Maybe OP is colorblind?

Small spaces will cause peaks and nulls in bass reproduction.  By opening doors or windows, there will be less of this, but bass will fall off earlier due to the lack or reinforcement.

Hahahahha.. Believe it or not wifi is also aided by open doors. Keep the windows closed though, unless you want your wifi to get out into the garden.

Closed small rooms eat your bass response in these slices. If you open the door, the waves get out, and won't cancel out.

You have your microphone located at a bass null for 65Hz. Wavelength is 5.3m, iirc you're looking at wave peaks and troughs every 1/4 wavelength (I can't remember basic physics) so every 1.3 metres.

Opening a door has changed the null locations slightly, but just moving your head or moving the speakers would result in similar shifts, and it would probably mean you get messed up bass in other locations.

If anyone has a decent set of speakers, finding bass nulls is pretty interesting- go to a site that generates pure sine waves, generate a low tone (40-80Hz) and then walk around the room. Your head will go in and out of bass nulls and peaks, it is incredibly easy to hear- sometimes the tone simply vanishes.

Edit- hard to tell what that graph means as it's missing the Y axis labels.

I'm looking at the subwoof,  there's no reason why it can't become a chair.

if it is built well enough, sure, although do you really want to be on it at full volume?

Google tactile transducers. I have four from Aura on my couch.

Some may find this exciting...
