Through the wall would be my very last choice. Even compromised wireless
a) crawl space? piece-o-cake. (I dropped a conduit from my stereo
cabinet into the crawl space :) )
I'm going to have to move my 10" subwoofer from the front of the room to the
rear. I can do it but running a wire through the wall will be a pain.
2) carpet? easy. Just tuck under the baseboard.
iii) wood/vinyl/tile floor? harder. remove baseboard and/or transition
and replace. touch up paint.
IV) no crawl space underneath? Run up through stud bay to attic and down
last) outside wall? drill through, run wire, back in. Seal hole, paint wire.
