RPG Skyline mounting on ceiling

(Somewhat off topic, yet relevant) I had my entire room's ceiling sprayed 1" thick with bleached-white cellulose insulation fiber. This is the same gray stuff found on warehouse ceilings, etc. It improved the echos & reflections considerably & was not very expensive, although it was quite a messy install. The cellulose worked well enough that I didn't have to completely hide the beautiful hardwood floor under full carpeting; a large wool deco. rug centered in the room does nicely. Also hung some artwork and various hook rugs on the walls all around, plus the curtains & stuffed furniture all ads up to some pretty decent room treatment and looks quite natural compared to the various treatment contraptions. I still do need to bass-trap one troublesome corner reflection though.

Bob, how did you determine the one corner bass problem? Boom...? Excuse my naivete. BTW, I have a similarly "cosmetic" treatment in my room and a rug covering the 1st reflection on the ceiling (yr cellulose is far better, I'm sure).

Rdr: why not try the usual decorative stuff on side walls, doors & windows: art, small carpets, heavy curtains for doors -- that look nice and absorb... perhaps, some of the skyline panels could be used for side or back walls with a suitable "cosmetic" touch (fabric cover?). I remember Abstract & others have been quite inventive in this respect with household items.

Good luck!

Hi Gregm will now try to answer your question ... (we've been away for holiday so I just got back online). I'm no expert regarding room treatments, but this one corner with boomy bass is apparent as I walk around the listening area. The bass accentuates when I approach the front lefthand corner of the room, and is also somewhat peaky at the left rear corner. Righthand side doesn't behave that way at all, as the room is asymmetrical. I'm stuck with speaker placement as-is but wouldn't want to change that anyway since I tweaked it for staging properties.
I think I need to experiment with a corner tune or a tube trap device or two, but haven't yet researched my options or educated myself regarding various posssible appproaches to fix. Roomtunes I am aware of too, but don't have space for those in our combo. listening room / living room area

Bob- found these articles on the Asylum by Jon Risch:

you can buy the three rolls of insulation in perforated bags for about $60 (quick and dirty) or take the time to build the trap with the wire. I'm going to try the quick way soon. can't lose, you can return anything to Home Depot!

i put them on my tin ceiling in small greenwich village apt, app. a foot apart, but they must be suspended with small wood screws or they will fall down! They do a wonderful job. Neighbors come in and say 'How is it so quiet in here?'
