Ok so today I'm leaning towards putting holes in the walls anyway. So... what sort of anchors should I use. I'm thinking the plastic ones that you drive screws into in a size where the plastic part is just slightly smaller than the holes in the brackets and then put a washer on the screw. The other option I think is to find studs and use 3 screws in the center of the bracket.
I just remembered these things came with a manual... I wonder what it says.
Sorta related. I have an Outlaw Audio LFM-1 Plus which is a down firing subwoofer. I have the carpet spikes installed but this place has some pretty deep carpet. I'm wondering if I should put something under it to raise it out of the carpet or possibly put the hard floor discs under the carpet spikes.
