Here in Asia most new construction is all concrete, yes- walls floors ceiling. Hard marble tiles. Not the best to control reflected sound!
Sometimes drop fiberglass ceilings.

What simple tricks can we do in listening rooms. Big rug, check. Wall fabric hanging things maybe?

Can't judge acoustic performance of room treatments by appearance.  GIK is the best.  They test, offer free advice, and use Owens Corning 703 high density fiberglass for superior results.  I had 10 2ft x 4ft of their 244 panels which did miracles unless than ideal rooms.

In my experience with Planars as Carver Amazing and Marting Logan they sound better in a live room as bricks or concrete.

Dipole speakers certainly help control first reflections (as implied by @FullRangeMan). Certainly, a rug between speakers and listener will almost always improve the sound. Careful positioning of speakers and listener also can be used to get best possible response. Bass traps help, but usually they are too large for domestic rooms. DSP in the lowest few octaves can help even out bass.

I had to return an entire GIK order due to glaring manufacturing issues that should have been caught in even a cursory quality control inspection. With a shipment to Asia, the potential for dealing with that kind of issue would be something to consider.

However, there are very likely local suppliers of room treatments depending on where in Asia you are.

Knowing more about the speakers you have and the size of the room would help. It would also help to understand the general issues you are working on. I assume reverberation from the hard surfaces is the biggest concern. Is bass boom also an issue?

Correct.
He dont mentioned what is his speaker or room dimensions.
I could like to have too much bass.

Alongside what you’ve already done, consider adding more soft furnishings to your room. Avoid speakers or equipment that sound overly bright in the treble, and try not to play music too loudly for the size of your space. Sitting a bit closer to the speakers can also help reduce the room’s influence on the sound. By following these steps, you should achieve a smoother, less fatiguing listening experience.

Hi, Sparkle.

I live in Taiwan part time, so I completely understand your issues with concrete.

Find a building supply store in your city. They ought to have insulation materials - fiberglass, denim, rock wool, etc. Then, either wrap the insulation panels with fabric or hire a furniture contractor to do it. DIY ideas: fill BIG ratan baskets with old pillows and place them in corners to act as bass traps; put a couple tall indoor plants in the room (remember to water them!); hang a cloth or cotton rug on the wall behind your listening position.

Until one actually lives in a concrete building with all four walls, ceiling and floor made of concrete, it’s hard to imagine how acoustically challenging it is.
