regarding setup...
the beomaster, beogram, and the beovox speakers are wall mountable if that helps.
1.) on the back of the beomaster you will see the screw slots.
2.) there is a wall mount "plate" available to "float" the beogram on the wall (horizontally ;-) )
in fact -there was a recent thread on here -a fellow was going to re-manufacture some.
chk this out: http://forum.beoworld.org/forums/thread/88691.aspx
3.) the speakers have a factory wall kit available, but at this point (time) they will be nos or on ebay perhaps -i forget the part # -but as i have a pair (nos) -i can check for you. maybe someone here has a pair available???
reg'ing the 6000 -perhaps it could be "floated" similar to the beogram???
hope that helps, and welcome to beoworld! enjoy!
