This might be a stupid answer, but a quick and dirty solution might be to stick the ATOM Echo inside a cup or other cone shaped object. I've done this at parties to make a phone's speaker appear to be louder.
This sounds like it wouldn't help much, and whatever increase in volume might be offest by decrease in quality due to echo. But it's free to try (and within my skill set :) ).
