you should be able to get wall/ceiling mounts that screw into the same place the floor stands do.
you will obviously need to screw into the walls, but you won't have to modify the speakers in any way.
you could also just install a small shelf, and then place the speaker on the shelf
I don't mind shelves, I was even thinking about placing these two speakers on top of my blu-ray/CD shelves, just decouple them with blutac or something similar. But this way I won't be able to angle them towards the listening position.
I was looking at similar mounts locally: http://www.electronicsforless.ca/b-t...bt-77-541.html - the ones that you have posted look better (flat plate), but have $65 USD shipping quote to Canada. I am just not sure what will hold the tilted speakers in the long run?
The bracket has a small angle on each side and included with the mount are pieces of rubber self sticking tape that you stick on the plate bottom and on the angle. Along with the pressure (can tighten the angle to speaker pretty tight) and rubber hold the speaker in place.
