Thanks for the reply 3db... The short answer on acoustical treatment is no. The SO is in charge of the decor, and enjoys the look of the LR as is. I'm fairly content to leave well enough alone on that front, as I don't expect to be taxing this system volume wise too much.
Part of my question here, which maybe I wasn't specific about was my choice of speakers in relation to the liveness of the room, and if any choice would be better than others because of that limitation.
Thanks JCP, The Onix X series seems to be well reviewed too, and should've been mentioned in my original post as an option, but thanks for the suggestion.
Thank you too Tomorrow....and Today too.

While being familiar with my JBLs in a studio setting, I'm not particularly fond of their sound. I was slightly arm-twisted into them in order to acheive a Dolby certification for the room, as they're more "cinema representative".
As far as the Internet Direct mfrs... I'm more than willing to give them a fair shake as some of them seem to have rather liberal shipping/return policies. Notably Aperion Audio paying for shipping both ways if you return them. Others are liberal, maybe not to that point, but I'm willing to test the waters in order to possibly find a little more "bang for my buck".
In all, thanks for the advice all... I will continue in my Internet based research before I pull the trigger and make a demo/purchase decision. I'm the type who likes to research to death before I actually make a choice, sometimes to the point of exhaustion, so I do appreciate the input.
