Hello!
I have a room I'm pretty pleased with, both sonically and aestethically. The last nagging concern is the midbass. I have a rough area between 100Hz and 200Hz that make many instruments lose drama and presence, and I'd like to try to make it better.
This is mainly for stereo, although it is in my theater.
I use Dali MS4 fronts (2,5 way floorstanders, two 6,5"woofers, rear firing ports, one for each.
Due to my screen size and room layout, the speakers are 65cm from the side wall and 1m from the front wall (to center of tweeter ribbon). The listening position is 140cm from the back wall. The room is 520cm long by 395cm wide, and 230cm ceiling.
I have two LLT sonotubes in the back of the room. I use Audyssey to integrate mains and subs and general room EQ.
I have treated all four corners with Rockwool triangles up to about 110cm height, then a 10cm rockwool sheet straddling the corner on top of that, so I treat floor to ceiling. The front wall istreated with stacks of rockwool triangles directly behind the speakers up to about 80cm height. I also have one 10cm rockwool sheet behind my center speaker against the front wall, and one 3cm sheet at either side of the center sheet. The rear wall has four 3cm sheets of Rockwool. The 1st reflection points on the side walls each have one 10cm sheet of Rockwool.
I can move the listening position forward slightly, but not too much, as I'd get too close to the screen. The main speakers can go forward slightly, but not away from the side walls, they are right against the screen already. They can go back slightly if I make some arrangements for my curtains (to hide the acoustic treatments and create a nice acoustically transparent wall.
Attached some measurements. The red graph is with Audyssey, the green is without. The 50Hz in the waterfall is obvious mains noise from somewhere. The predicted frequency response is pretty similar to the real one in the problematic region.
