Just as an FYI, a 20'x20' room is going to have significant bass issues that I wouldn't trust to do a final mix in.

For reference levels, Dolby specs a 20' room length as the minimum, sitting 2/3 of the room's length away from the front wall / screen, with the speakers behind the screen at the front of the room.

That's ~13' from you to the monitors for Dolby specs using 85dBC. And I think one of the other factors that plays in 85dB for larger rooms is that acoustically transparent screens are not perfect, and diffuse the sound a bit to take the edge off louder sounds.

I'm sure others will chime in though that have more experience in this area.
