To locate the first reflection point for the acoustic panels, sit in the primary seat, and have some one slide a mirror along the wall until you see the speaker.
That is the first reflection point for the primary seat. Correct?
I did that and the relfection point is a lot closer to the screen than I thought it would be.
I positioned the first reflection point, where the main 3-4 of the main seats are covered on the first panel. I have not hung them yet, but the furthest out seat has a little weak coverage for the first point, per speaker of course.
I will post photos in the build thread... (beginning the finish out, now what...)
Understood. I'm just saying that you have a reflection on the left wall from both the left and right speaker - so even for YOUR seat, you have at least 2 points on each wall.
Got chu Brian;
the second panel postion per wall will be placed at that point... Hopefully its at a semetric, pleasing location, but I am sure it wont be...
a third panel will be placed on the one wall, the other wall has a door in the way.
And don't forget the Ceiling and floor as well. Assuming the speakers are ear height, you can just split the distance between you and the speaker in half (so you're not trying to slide a mirror across the ceiling).
Generally, the ceiling is the last thing to be treated. If you assume that tweeters are at seated ear level, you can draw a line between the left speaker and the left most seat. At the center of that line, go straight up.
Repeat for the right to the right most seat.
As long as you cover those 2 points and between, you'll get them all.
No real need to attach them in any way. If you're going to frame them (recommended) they'll friction fit into the frame and the cloth will hold it in place.
Thanks for the reply.
I am using speaker fabric so I don't think it will do much to maintain the alignment. These panels are also 6' tall made from a panel and a half so I guess I need to build the frame for support. If I were to insist on securing them what do you suggest?
My mains are towers & located on a front stage 10 inches above floor. By removing front feet I was able to angle speakers down forward towards seated mlp. I am trying to locate ceiling panel positions. Given speaker height does this change your recommendation ie straight line left speaker to left seat & straight line right speaker to right seat?
I had 2 cups already so my caffeine already kicked in I guess. Hanging 242 panels on ceiling. I noticed in an earlier post you mentioned to draw line between left speaker & left seat & locate the mid point straight up & locate left panel there. The same for the right side. My question is my tweeters are 64 inches above floor located on front stage. Tweeters are above seated ear height so I angled down tweeters towards mlp. Does your rule still apply or do I need to make modifications. Note your earlier post was from 2009. Not sure if rule has changed.
That method only works if mid/tweet are at approximately ear level. With them up higher, the points will be closer to the speakers and not 1/2 along the diagonal. Understand you also have to do between that left and right point.
