Ummm... the door isn't the problem.
Here comes the unsolicited review:
1. No diffusion/absorption I can see.
2. Wall to wall - eats mids and imaging specificity along the lower part of the soundstage.
3. Equipment rack: interferes with center imaging
4. Turntable getting hit by bass notes, but thankfully no flimsy cover to rattle - nice table BTW. Can't make out the arm.
5. Is the side wall longer than the front wall? If so, you are getting extra midbass where your speakers are located. On the long wall you'll get a wider stage, but if you are closer it could be near field listening which the speaker may not be set up for.
6. The speakers are the same distance to the room boundaries. So however one speaker is off of flat w.r.t. room, it's doubled. In bad cases one can have 6-8 db deviance plus or minus somewhere(s) under 350 Hz. The ideal room ratios are 1/1.7/2.3 or 23x17x10 in feet. This looks like a single driver speaker with transmission line loading which is fine, but the back and side wall appear to be equidistant the the driver and port(s). If this is part of the design, great, if not you've got a peak and a dip of probably 5db each if not more 0-350 hz.
Parallel walls, lowish ceiling, probably lots of slap echoing and standing waves.
Just a born critic with lots of professional experience setting up and spec'ing listeng rooms. No insult intended, but I think if you have some leeway you could get better sound, Or actually strayngs.
And of course, love the dog.
