I'm using 3M Command Display Ledges. Small and allow the Holostages to be placed horizontally or vertically. They use the command strips which make replacement very easy. I wanted the option of changing the orientation or location easily. I used nanotape first. It works very effectively also, I just prefer the small display ledge.
Thanks for the photos and the idea of the 3M ledges. I found both them remained better from falling with wide nanotape. Before putting a pair on the front wall, 5' up and little inside my bass trap stacks, they were on my ATC floorstanders. There the blocks were effective but the front wall opened up the sound even more. OTOH, there was an attractive touch of warmth on the speakers that disappeared with new placement.
One thing about these blocks is that their effects are unique and obvious. I don't even feel pressed to A-B them, because there is nothing I have, or have added around the same time, that could have brought about the level of ambient 3-D staging and clarity that these blocks do. On the photos I posted earlier, one can tell from the system placement in the room that the right side sound might not be as pronounced as the left. These blocks have gone a long way to mitigating that. Thanks to Will for bringing them to my attention.
For some reason, my post went up before I had written anything. Take a look again. The other two blocks are on each side just behind my head. Haven't played with those yet.
