Was the resonance in the room similar with other speakers
Ha .. AN makes me think of bell bottom pants .. I agree !My AudioNote speakers never worked in my current room.I bought them before moving.
As I said, I am really pleased with my current speakers. I don't plan on changing them! I can spend many hours listening without any "fatigue". They make my AN speakers sound terribly colored and veiled.
I am quite sensitive to "resonances", and I've heard many systems in poor rooms that have completely turned me off. This is not the case here. It is simply a matter of optimizing things.
The last RT graph I posted is pretty good (< 400 ms on average, which is acceptable for a fairly large living space). I would simply like to take things a step further...
Open baffle speakers work very well in medium sized rooms.
the link does not work. Can you check it ?This is a paper on the design of room by the acoustic engineer .. it shows how the ceiling baffles are set out .. you dont need that many

You could do tempoary baffles with any rigid absorbent board you may already have .. if they worked there are plenty of elegant ways of achieving a similar result with say timber battens and black absorber behind
Cornice needs to have some depth to work
Cool .. that should be interestingI ordered basotect corner bass traps to test them on the ceiling/wall intersection above my couch. They are very light, so it will be easy to tape them temporarily. I am not sure how effective basotect is in this context, but it's worth a shot. I will also try them placed vertically in the corner behind the left speaker.
I also ordered a few rectangular basotect panels to play around with on the ceiling and walls. If rigidity is an issue, I'm thinking of adding corrugated cardboard behind them.
If some of these tests are conclusive, I can then think about devising a system of detachable panels (with thin magnetic strips, for example). The corner traps could be set up permanently, however (and for those I could then consider more efficient absorption material).
Basotect cannot be painted, but it can be covered with acoustically transparent fabric.
As mentioned, my entire system in my living room is normally hidden out of view, and it takes me a couple minutes to set everything up anyway.
Low frequency issues are always harder to solve. But for the midrange and treble, looking at the photos, I now do think that a lot of the extra resonance are coming from the windows.I did try placing some panels hanging from the ceiling above my couch, as was also suggested, and it seems to have more effect than placing panels against the wall above my couch, but it is not "viable"... There are a couple more windows that I can put curtains on, and will see after if I need to do much else.

But were you able to try putting those throw pillows you have on your couch and put them right behind your ears when you're listening to music? The pillows should sit on top of the back of the couch in a very stable manner so that the trebles (and midrange) won't hit the back wall and bounce right back into your ears. I've found even though the pillows are not professional acoustic panels, they still do a good enough job that it helps preserve the aesthetics. Sometimes you might need to move the pillows slightly because it all comes down to where the first reflection point is from your speaker to the back wall back into your ear as you'll want a throw pillow there.
