Happy New Year to all!
And here the story continues:
Optimizing Room Acoustic:
Optimizing room acoustic is a must do for having best sound performance. To optimize the acoustic of a room is not a easy doing. Every room has other acoustic problems and there is no general rule what is to do. In best case you should be adviced from a profi. I am also a rookie, but I spend a lot of time with many tests to optimize the acoustic of my theater and finally I have installed some do-it-yourself acoustic elements which have done the best results in my tests.
First I have filled the front stage with foamy material around the subwoofer.
To minimize roar from the subwoofer and improve dialog reproduction, I have placed two big rolled foamy mattress in the left and the right corner of the front.
Then I have placed a acoustic element on the left wall nearest to the screen. This element eliminates reflections from the wall. Without this element the tendency of the front sound is to the left side.
The element is build from the same foamy material I have used for the front stage. The material was covered with black Molton.
In the back on the right corner I have installed a big acoustic element that also reduces roar from the subwoofer.
