Sure, Brian, at least a little, if you mean that the bracket will be directly on the wall, but first experiment. Use a stack of magazines or whatever and position the M3s an inch or so from the wall to sample the effect.
Edit: but if you mean what Randy suggested, then no. It's the relation to the wall itself which is significant. Just putting some object close to the port would have a negative effect, if any. Again though, experimentation is possible: stick a big heavy book or similar about an inch behind the port.
