Thanks for asking this question. Since my PSB's aren't selling, I figured I may as well add them to my main system. I'll be interested in knowing which set up you used.[
You're quite welcome my friend, I decided to go with rear (backs) and also the same brand and model of my sides (ARX A1b's), I haven't decided yet if I will put them on stands (have (built) stands) which would place the rear speaks about 1 and a 1/2 feet above ear level, also contemplating ceiling mounting, so as 3db once said, I don't have to move them when I vacuum
. I also liked that hanging basket from the ceiling look, instead of a basket put the speaker in it.
Cheers Jeff
