I’m ready to install two of my IB318’s into a manifold. The screw holes in the speaker frame are covered by the part of the rubber surround that is glued down. If I put a screw through it, the head of the screw seems like it might be awfully close to the surround itself, cutting into the part that is glued down. Are these meant to be mounted some other way?
No no no screws.Use round head bolts that require hex allen wrench.
No no no drilling into speaker frame as all speaker frame holes are predrilled at factory
Mark with pencil on mdf where bolts holes go then place speaker off to floor carpet and gently drill on mdf and only mdf then place bolts then after wrenching bolts all the way in mdf then remove bolts from mdf then place speaker frame and gently place speaker bolts use bolts nuts with flat washers and bolts nuts with plastic anti spin ring aka security nuts.
Remove rubber gasket from speaker frame and notice on back of speaker frame 8 predrilled bolt hole s now gently use a small nail to remove rubber from these 8 predrilled bolts hole and only from these 8 predrilled bolts hole so that the 8 bolts can fit into the 8 predrilled bolts hole and place speaker gasket then place speaker frame on mdf then gently gently place bolts into holes

Don't think anyone mentioned drilling the speaker frame.
Type of screw and type of head are not linked. I like square or Allen socket head screws so I don't slip and punch a hole through speaker.
Many people use normal wood thread screws without issue. They are better in plywood than MDF.
If using machine thread bolts, definitely spend some time making sure nut can't spin. Nothing more frustrating than being unable to remove a bolt because the nut spun free. There have been many threads over the years debating the merits of T-nuts, hurricane nuts, epoxy, screw adjacent to nut flange..
