How U determine first and second reflection points


Someone told me following a while ago in room teak thread, but I don't think I understand it well. Any comments?

Have someone sit in the primary listening location, take a mirror to the side walls opposite each speaker and move it until the seated person can see the speaker reflected in the mirror. These are your first reflection points. Start from there.

The ceiling wall junctions all around the room should be treated as reflection areas. To me these are the critical areas to treat not to kill but to redirect the pressure back at the listening position. You want the energy that usually flows along the surface of these large planes to become a part of the overall experience..Tom
David I suppose you could follow as so many others do the same old pitch of foam and fiberglass that so many companys build..These products often do as much harm as they do good..they reduce energy in the room and often suck out the life..Tom
