The room is about 13'8" wide. So I set up the baffle at around 3'2". The speakers are set at 30deg. and the listening position is around 5'8". I am starting on the stairs tomorrow, beef up is complete and the control room walls will be going up next week. Line of sight for the main room is going to be good but I am going to put in cctv for the vox booth.....bummer. If I got rid of the bathroom the line of sight would work, but you have to have a bathroom.
Check out this file and see if I am headed in the right direction. https://www.dropbox.com/s/15c442lf70sp24o/final%20layout1%28SOFFIT%29.skp?dl=0 Hey Stuart, I finally realized what you were talking about with the speakers as far as distance from side and height. I know the side walls are not all the way finished but I was just making sure the angle of the wall would be ok and making sure where the glass will be is going to be correct.
Hey there Marc, you seem to be doing well! The new layout is looking good, the dimensions seem fine, and I'd say you are definitely on the right track. I think what Scavneck was talking about is the positioning of the speaker on the soffit baffle: It should not be spot in the middle of the baffle, but offset to one side or the other, such that the distance from the acoustic axis of the speaker to the edge of the baffle is different in all directions: So it is not centered either vertically or horizontally. In other words, the distance from the center of the speaker to the left edge of the baffle is different from the distance to the right edge, and both of those are different from the distance to the bottom edge, and all three of those are different from the distance to the top edge. The "2/5" measurement he mentions is a good starting point, meaning that the acoustic axis of the speaker should be about two fifths of the way across the front baffle of the soffit. The reason for all of this is to reduce the "lobing" effects of having a sound source centered in a panel. So you should modify your soffit design to ensure to take that into account. Another point about your soffits: they need to be built very rigid, strong, hefty, tough. The idea is that they cannot be forced to vibrate at all by the speaker. They must be able to resist that. - Stuart -
