The riser marks are the big bumps on the face. The little goosebumps you're talking about are just texture, a form of finish that hides surface irregularities. The riser marks are actually formed where the plastic is injected into the mold. Both can be finish-sanded smooth. Just be careful and don't go so far that the throat opens up. Only take off enough to remove the texture and make 'em smooth.
That's great news! I'll try to keep the throat the same diameter. When you mention the face, are you referring to the area where the 6 bolt holes are? Also, is it enough to just use wood screws to mount the horn into the 3/4" ply, or should I use hurricane nuts and bolts (I'm using hurricane nuts and bolts for the 15" JBL.).
