Now while I may not be an expert in acoustics, my physics is above average and sound does not behave any different in audio than any other pursuit.
Boundary issues would be a factor of wavelength and distance to the walls. Whether you have a big speaker or small speakers, they will behave the same effectively. I would have to give it more thought, but the larger emitting surface area may even have a distinct averaging property reducing the boundary effect.
You are going to have to try much harder with your drive by poorly disguised insults.
