This effect is due mostly to room acoustics, but at high frequencies loudspeaker beaming and the microphone's off-axis response are also factors. The good news is adding acoustic treatment greatly...

You're probably on the right track, but without photos or a drawing it's difficult to say for sure. For example, are the speakers at the top or the bottom of the T? Do you have digital camera or...

The main feature of an acoustic panel is how much it absorbs. Not only "overall" but also at various frequencies. Thin panels absorb very little at bass frequencies, so the room might seem dead...

Absorbers on the rear wall behind you need to absorb all frequencies including mids and highs. Those are very strong, very damaging reflections. Especially when the wall is not very far behind you.

You'll probably get some membrane absorption from very thin drywall, but you have no assurance it will be at a frequency range that's useful in your room! So I suggest normal drywall and normal bass...

Any bass trapping you can get is worth doing. But small holes won't expose enough of the interior insulation. If you went to all this trouble so far, you might consider re-doing the soffits and...

That's pretty small for a bass trap, but if you can't or don't want to make it larger, yes, stuff it with batt insulation. You could optionally use 705-FRK rigid fiberglass, and that would be even...

Yes, it can and should be a bass trap. So build it as an empty frame as I described, stuffed with insulation and covered with fabric rather than something solid or rigid.

The only way to know for sure where your subs give the flattest response is to measure the LF response of your room at high resolution as you experiment. This will help:

Neither of those propose placements are ideal. Can you move the TV to the right some so it's centered left-right in the room? If you post a photo of your space I'll be able to offer better advice....
