FWIW, I would prefer to have the speakers backs parallel to the long wall, with absorptive room treatment behind the listener.

It's way too late for that. The walls up and staying up, right where it is at.
Trust me... there are a few reasons why things are where they are. Bedrooms, kitchens, bathrooms, and hallways have to be accessed. I suppose I could have put the speakers on wheels instead of spikes though... well, at least one of them!
Thanks for the thoughts on the room treatments anyhow.
Forgive me, but I fail to see the application of the Bamboo in this scenario... mind expanding a bit more.
I'm already tossing around the idea of using wicker/rattan/ loosely woven 'basket like' fixtures almost like African or Asian war Shields but in a more open fashion, to be used as on wall or on mike stands, diffusers.
....but Bamboo? Sorry, but I just don't get it.
Sorry... I simply did not get the correlation, as I was focusing initially on filling the spaces between the studs on the rear of that wall with absorptivwe materials. You are right though... difussion is in order too and bamboo would be a nice fit in my room decor.
Good idea... I'd have to find them split, or pre cut. or pre cut and pre glued/formed.
That last item you mentioned, 'molded'... embossed... a link to them/it would be a big help!
Blindjim - the main frequency "amplified" by your room will be 1125/(23x2)= 25Hz. Unfortunately lack of absorption creates standing waves with peak and valleys at different frequencies at the different location. To tame it you'll need at least 4" high density material placed some distance from rear wall. 4" panels are not common and are expensive. Better to concentrate on removing higher bass resonances. To do that you need 2" thick 4'x8' panels of high density fiberglass like John Manville 817 http://www.jm.com/insulation/performance_materials/products/ci9_800series_spin-glas.pdf
814 is more common but has much worse absorption coefficient at the low frequencies - I ended up buying twelve 817s.
I was once in the room that had all spaces between studs filled with 814 or similar Corning material with fabric over it. Amazing acoustics - you can hear voice so clear and pinpoint exact location/person. My panels are in the making - got backboards, fabric glue etc. but am too busy (read lazy) to finish.
Owens Corning might be more common in your area:
