tipatina Posted September 27, 2019 Share Posted September 27, 2019 My listening room/theater has acoustic foam covered with painted cloth to match the interior on front and rear walls, side wall are painted sheet rock. The foam really improved the sound (Forte II/Crites) I am interested in Khorns but the front wall covering will result in corners that have acoustic foam in half of each corner. Can anyone predict how this will affect the corner speaker performance? 1 Quote Link to comment Share on other sites More sharing options...

This is plans that PWK drew up for a false corner. You have corners so 3/4” plywood of these dimensions should work. Quote Link to comment Share on other sites More sharing options...

Unless the foam is more than about 8" thick, the bass won't even notice it. 1 Quote Link to comment Share on other sites More sharing options...
tipatina Posted October 30, 2019 Author Share Posted October 30, 2019 Thanks for he replies, reviving this because I have rethought it. I have another room with perfect corners on the front walls but no rear wall, (opens onto stair landing.) Would the absence of a rear wall be a problem?

The lack of a rear wall might help avoid standing wave problems. 2 Quote Link to comment Share on other sites More sharing options...
