That's the pic I have with a new driver.
By the way, coming to the issue of opening the sub, the snap fit points are atleast 1 or 2 inches deep from the outer frame border.
So if you insert just the tip of the screw driver and try to open it may not come, and it may damage the edges.
We have to insert the screw driver atleast one or two inches deep, and then pull the frame out.
