Wood screws in MDF...are pilot holes needed?

Agree with this. Just drill from below, recess the bolt heads and then cover or paint the bolts black. Will be much easier getting something in there to hold a nut then to get the torque needed to screw into MDF. A ratchet should fit right in there.

There are right-angle adapters for drills that would help in this case. They are not cheap as they are intended more for drilling holes in stud walls and what not. However, if that would fit in the space, it could save you a lot of grief in fixing other damage.

Yeah that's a great idea, but I'm too anal to do it. You see, the "ceiling" of this cab, where the speakers are, is the ONLY place with the original finish...and hasn't been molested or spray painted by an op. It's all nice and shiny and lustrous. No matter how good of a patching job I did (which wouldn't be a very good job, I might add) I would still notice....and it would bug me. Asymmetrical and stereo speakers don't mix for me hahahahahaha.
I also like the L drill idea, but I've already spent way too much money on this thing for that.
The adhesive options would give me nightmares, cos I'd always be thinking the speaker's gonna come loose at any moment and crash into the yoke. I thought of maybe tacking some thin nails in there to hold it up. Unless the cab got turned upside down, the speaker would prolly stay secure.....but now that I think of it there could be bad vibrations if it's loose like that.
Decisions decisions.....
Necro:
Construction adhesive will NOT come off. Even if you want it to later if a speaker dies - it will rip apart the MDF.
Also, here's another option.
Make a frame for each speaker, attach the speaker to the square frame. Have a wood 'bar' going across each of the frames with L's down on the sides. Bolt the sides into the wood holding up the 'ceiling' of the cab that you don't want to drill through - since you can get a drill in there horizontally it looks like.

On top of my other problems, I accidentally got brass screws. Those should go great with my magnetic screwdriver. :angry:
BTW that frame thing is a pretty good idea. Heck, I could prolly just make a frame that attaches to the existing speaker.......made of coat hangers.
My lunchtime for the past week or 2 has been spent in the hardware store......grrrrr.
