I can't do the pictures right now, nor today, but here's a description.
Duct coming up from room below. Looking at it from hole where speaker goes, you are looking at the wide side of it. It measures 8 x 14. You are looking at the 14 inch side. It needs to move farther away from you, then back up, to make more room for the speaker. Instead of moving away from you, the offset goes to the left (or right), then back up instead.
The Offset bends on the 8 inch side, leaving the 14 inch side flat.
The Riser bends on the 14 inch side, leaving the 8 inch side flat.
There will be a quiz next week to see if you can pass your HVAC class.
