Hopefully, we're going to be moving to a new house with a larger dedicated listening room   The room is 18'6 x 13'8 with an 8' ceiling.  The only thing is...  the wall where the speakers are going to be has a sloping ceiling.  Looking at the ceiling it starts sloping about 4 feet out from the front wall and slopes to about 6 feet.  Is this going to be a problem??  I sure hope not.

looking at the wall from the side (if you could) would look something like this:

It's something you need to consider.  Normally for a 2 channel room with that type of vault (assuming the vaults run down the side walls), I spec a series of framed 6" wide x 3' to 4' tall absorbers spaced out about every 15" on center.  This provides a bit of absorbtion without getting too dead and the frames act somewhat like a crude well diffusor.

Hi,  the vault is behind the speakers - the rest of the room is normal.  The sides are normal.

Thanks

Then I'd just kill it or straddle the wall/first angle behind the seating position with a thicker soft absorber.
