1st, Enter 'room mode calculator' in Google. The lengths of sides being 2 1/2 times the height is awful, not to mention the room being square!
2nd, In this case the room is really your enemy. Spend some time and money on the room. If the total budget is 20 large, apportion some of it to getting the acoustics fixed. Do that at the same time you install your stereo.
Finally, 'Add a sub' is probably not advised at this point. When I did as I suggest in point #1, so many frequencies popped up that were even, or near even multiples of 20hz that I can only imagine the room as a big, vibrating echo chamber.
You can put 20 large in speakers only, which is 2x what I have in my entire, reasonable sounding system, add another chunk into electronics and a GOOD source and still have unsatisfying sound. Before you get on this merry-go-round, consider your room.
I'll bet your EchoBusters are some of the best money you ever spent! Low Frequencies are the absolute worst!
