Hello,
Recently received a long awaited speaker order, a set of LS9's, and want to add more treatments to make the room more suited for the new speakers. Problem is I don't know much about how best to treat a room for this type of speaker, or in general for that matter. The room they are in has ATS panels, and a GIK tri-trap pair, positioned based on replies from Bryan at this thread
http://www.audiocircle.com/index.php?topic=67082.msg618987#msg618987. As stated in the referenced thread, room dimensions are 16ft wide, 19.5 ft long, and ceilings that are 10ft high that vault to about 15 ft between the mains and the listening positions.
The first suggestion made in that thread was to get the 4" panels mounted on the ceiling to cover the peaks of the vault it has. Could not accomplish that, because I had no way to get up to the height required to place the panels there. Ironically, the LS9's may have solved that problem for me....the shipping crates (coffins), they came in look big enough and sturdy enough where I should be able to use them to increase the height of the ladder and get where I need to be to mount the panels at the vault's peak. Now that the room has the LS9's is the vault still one of the first things on my list, or has the change in speaker type made this unnecessary?
This link has pictures of the room with the panels, the LS9's in position, and a few other shots showing the front, rear and side walls, and the ceiling:

I purchased a set of four used eighth nerve adept triangles, and am thinking of using two at the front/side/ wall ceiling corners. Does it make sense to do this, given the GIK tri-traps on the floor of these corners? Also, when covering the peaks of the vault, do I need to get as close as possible to covering the entire vault (width of the room)? It would be about 4 24x48x4" panels to get the entire vault, or would getting most of it with 3 of the panels be fine?
Another question is what (if anything) to add to the front wall behind the speakers, I am somewhat limited with the screen. Currently it has two of the 24x48x4" panels there (almost directly behind the speakers)...have been thinking about adding four more to get panels all along the bottom of the screen, as much for visual reasons as any sound improvement. Want to have a uniform color/material along the bottom of the screen. With only the two panels sometimes the wall below the screen has two colors from the projector light over splash displaying on wall vs. panel. Will adding panels here give acoustic improvements, or could it actually make things worse acoustically? Also, are the 24x48x4" panels being wasted in this location, Bryan mentioned the two inch panels were fine in this location in the earlier thread, but not sure if this was because of the speaker type (Mini-strata) and what I had to work with in panels, or if 2" panels generally are o.k. behind all types of speakers (e.g. stratas vs LS9's). If 4" panels have advantages in this location, am willing to purchase them instead of 2" panels....but if there aren't any reasons for them, the 2" panels are a less expensive.
I was thinking of getting four 24x48x2" panels to cover the french doors, two more to fill in gaps at the back wall, and four to get the side walls above and below the surrounds. Overkill?? If so which if any make sense? As seen in one of the photos, have a 24x48x2" panel in the middle window, this is typically covered by the curtain....does the panel still work o.k. with a curtain covering it? Most of the time the french doors are open, that frees up two of the panels slated for the doors....good idea to put them in front of the other windows...maybe with stands...make sense?
Answers to the above questions and other treatment suggestions are greatly appreciated.
Thanks,
John
