What would be better for movies in a 16 x 20 room? A 15 inch Atlas sealed (up to 4 cubic feet) with 350 watts or a 12 inch Atlas ported( up to 4 cubic feet with 350 watts?

Assuming when they call me back, and brokering isn't too $$$, I'll end up picking up a single Atlas 15"

I'd rather have too much than too little.

For the $5 difference you must go for the 15"

but what about the box size will 4 cubes be enough?

For HT, yes. 4 cu.ft slightly larger than the recommended size for a system Q of 0.707 (assuming you set the driver Qts to 0.37). This will give you semi-musical presentation with plenty of impact. A larger enclosure will give you slightly smoother roll off to super-low frequencies, a slightly more musical presentation, and a slight improvement in efficiency. 350W will be plenty of power for this project.
