Gnobber, Did you mean that your panels are 18 ' wide? Im experiencing some standing waves resonating in my room on certain material and have fixed some of the problem by hanging some plants in the top corners but it hasn't fixed the problem completely. Im trying to follow what you guys did but im still not sure exactly where these panels should go. Look at the pic of my system and see if the ceiling resembles yours.
Guidelines for treating cathedral ceilings
My listening room is 18' wide x 18.5' deep, with a cathedral ceiling symmetrically over the room.
I have done the 'standard' room treatments (absorption behind the speakers and listening seats, and absorption at the first reflection points on the side walls). Absorption is 2" thick Owens Corning 703 fiberglass.
However, I am still hearing a sharp slap echo when I clap my hands in the room. I am beginning to suspect some sort of ceiling or upper corner interaction. Is there any rule of thumb for where to first start with a treating a cathedral ceiling? I am a little bit surprised, since the ceiling is angled and does not present two parallel surfaces for sound to bounce off of.
The practical concern is some sibillance when playing certain CDs at high volumes (possibly exciting something in the room and exaggerating the treble?).
thanks in advance,
Bill
(I hope this drawing comes through OK- the A is the top of the ceiling, and the two S are the speakers).
