So it is essentially the first floor of the house with an open floor plan?
As far as the WAF situation, my wife didn't care what i put in our family room since it only really gets used by us, so ascend acoustics were perfect, but in our formal parlor where guests have to work through to get to the rest of our house she gave me some "guidelines" no black speakers, nothing taller than x amount of inches, no more than 2 speakers, ext. Which I kind of conformed to, end result we were both happy and she listens to it just as much as me... Happy wife = Happy, uh, well... Wife"
There are tons of nice looking speakers out there, I would stay away from vinyl if it is going to be critiqued or treated like furniture, stick to something piano or veneer...
