The room is 5.4 meter width and one side of the room is 9 meter and the other side 12.6 meter. The height is around 2.65 meter.
The floor is from nature stone.
I have no picture.
So roughly 16 x 27 by 8 feet .
That's almost the same size as my room one - which is 17 x23 x 8.
That's a good size room and I am surprised you are having bass issues to the extent you are. Anyway when you get the room tested it will tell you where the frquency peaks are - deal with them first as the ear hears peaks more than dips in response. Also when you fix the peaks the the dips tend to come up in response. Also the "Q" of the dips and peaks enters into the equation because the broadness of the Q or the sharpness of the Q affects frequencies on either side of the bump or dip.
In my room for example I have a bump at 50Hz and a dip at 100 Hz - which I got rid of by using our active speakers and EQ-ing them out.
But for what its worth I have experimented with traps of all sorts and its a mixed bag because the size of trap you need to control lets say a 50Hz bump is very large and the size of trap increases exponentially as you go down in frequency. Also, and this is just my opinion, I find that too many traps starts to rob the room of its natural transient response and things start to sound too dead and lacks a sense of life.
If you notice when we do these audio shows you will never see me using room treatments. We always get great sound and the reason is that our speakers are designed to take the room reflections into account - but that's a whole different story.
