i asked a similar question a while back and got some very well defined answers from the enlightened ones on the forum. i think first it's wise to take a step back and get a more complete answer on RFZ. from that point of view my personal opinion is i wouldn't follow the layouts on the sayer site as being final outcomes but more "concepts". there is quite a bit of detail missing from them especially in the form of not enough acoustic treatment shown. especially when it comes to frequencies below 250hz
here is the link, hope it helps.

Glass must be kept out of those zones or you are faced with placing panels in front of those highly reflective surfaces. Hence the advice to move the glass south or eliminate it in this design on the west wall.
The problem is that on the John Sayer site, his central control room design has sliding glass doors in those critical areas on both sides. What am I missing here? Does it have anything to do with soffit mounted monitors? Variplans
