No until now i just made a quick listening test, and it sounds good for my ears.
After i build all the Diffusors i want to bring into the room i will place them by measuring, moving, measuring .......
2 QRD P11 without divider are ready to move to the sidewall at the back of the CR, and 2 deep skylines will be started to build today.
The 2 Skylines will be placed at the cloud left an right short behind the listening position. exact placement will be found be moving an measuring of course

cheers
Mika
