Topic: Acoustic Ceiling:
Many people are familiar with those wood/felt panels from hardware stores and similar places.
It is clearly noticeable that the felt reduces the reverberation in the room.
However, I prefer the look of the "Ligno" system.
From the room side, I don't see any surface that could absorb sound, only wood.
Does anyone have more expertise on this and can tell me to what extent this can reduce reverberation in a room (in my case, a living room with hard walls and very large windows)?
Would adding additional insulation wool behind the panels result in greater sound absorption?

My first question is, why do you think you will have that much echo in such a small living space?
In a typical house, there are furniture, rugs, decorations, lamps, pictures, plants, and so on.
It is quite rare to have such a problem under those conditions.

Or are you planning a very minimalist interior design including a tiled floor?

There will actually not be much sound-absorbing material in the room.
The main factor here would be the sofa, and that’s basically it.
Neither the hardwood floor, the thin curtain, nor the few plants will make much difference.
Instead, there are large glass surfaces and hard walls.

And a living room is, after all, also a space where you want to listen to music properly sometimes.

You can achieve something with fabric curtains, acoustic absorbers, ceiling panels, and carpets.

Ideally, a thick carpet on the floor, walls, and ceiling 🙂 but usually unattractive for a living room… although it is practical in a way if you can just vacuum your walls and ceiling haha

We have a larger open-plan room,
with natural reverberation,
the receiver’s room calibration system did a great job compensating for it.
Tip: avoid a subwoofer, as it causes interference and cancellations,
use two large speakers with a frequency response down to 20Hz, and two surround speakers down to 50Hz, for good sound quality.

Yes, that's correct.

However, I would have recommended 5 bookshelf speakers and two subwoofers instead. Having two subs in the room can effectively reduce room modes and provide the bass pressure that might be missing in certain movies.

Alternatively, you could simply buy powerful active 2.0 floor-standing speakers, costing 1,895€ each, from Schwäbisch Gmünd.

Better a good 2.0 system than an "okay" 5.1.
