Hope someone can help. I have 8 GridFusors. I want to hang 4 of these on the upper left and right side walls of my room at listening position (my listening position only 4 feet from the back wall). I was going to hang them in an alternating pattern, one horizontal (slots going horizontally) and the other vertical. Does the pattern on the opposing side walls have to be mirror images? By than I mean, if one GridFusor on left side wall on the same spot is hung vertically, does the GridFusor on the right wall on the same spot have to be vertical also (or should I have it horizontal)? Thanks.
BTW, I tried using double sided tape, but because the GridFusors are porous, the tape falls off over time. Tape sticks to my walls fine. GIK suggests alternate method using pins. What kind of pins? I have dry walls.
