A lot I think. The drawn lines are PH with the arrow direction on flow. From left to right I have a 1400 and a 1050 hidden under the shelves one blowing up into the corner and one tracing the sb toward the right side. In the middle coming forward is another 1400. On the right side I have a 1250 blowing down the back glass a wp40 on wave coming up the middle to the front glass and a 1600 blowing the distance of the front glass + return.
