My understanding is that it's not quite as simple as that, an untreated room will have problems across the whole range but the bass is hardest top deal with.

Hi Sam. I didn't test the duvet just yet. But yes that is on the menu. You see my plan is to try out this REW software I downloaded starting with a naked room then bring in the DIY stuff and re-test. Im hoping to see what DIY stuff works, doesnt work, kinda works etc. My home made absorbers might work if i select a higher range of frequencies in the REW sweep. At present Im testing from about 40Hz to 300Hz.
I just picked that range arbitrarily.
Now my panels may not need to be ditched but I might have to put deeper sides on them. I really made them too shallow which was a silly goof on my part. Im concerned about the weight of the panels and wood can be very heavy. That guy on YT who tested bathroom towels? Tried it. Didnt make a blind bit of difference to the graph. I'll keep you updated Sam. Bank holiday weekend here. So...pub :)
I was replying to that particular post, forgive me if i missed some reference to wider range testing (I can't take time to re-read the whole thread just now). If you had no treatment in the mid/high range you would almost certainly find stereo image and detail compromised but, yes, the bass end is most troublesome in small rooms and, quite likely impossible to fully control hence the fact that the advice is directed that way.
FWIW my own room sounds pretty good and works for me as a (compact/bijou) recording mixing and rehearsal space but the bass end is going to be a bit wayward. I used REW when I first installed the treatment but have now moved on to just enjoying my 'studio' for what it is, i.e. not Abbey Rd but a nice place to play, record and listen to music. It's not perfect (far from it) but it serves my needs (and for mixing headphones let me check the low end for any obvious anomalies).
