One thing to think about when constructing speaker system is that a screwdriver shoved through a speaker cone is, in polite quarters, a bad thing. Polite quarters cause it tends to cause bad words. Like Harry type bad.
This is why drivers are often mounted with hex head screws. Much tougher to slip in disasterous ways. But there is things you can do to help yourself no matter what...
-Work with a good balance personally and have the speaker in a solid position so it doesn't move.
-Use a hand in a protective manner so that you can deflect a slip if it should occur.
-Use the right tool for the job.
As in with a Phillips, use a #2 if it fits in firmly and if not and it's smaller then go to the #1. You'd be surprised how often even a rather small looking head screw is actually cut for the #2. If you've experienced the screwdriver turning in the head and stripping the edge off the teeth of the cuts, then you were probably using the wrong screwdriver.
There is a difference, know what kind of tip you have on a Phillips and always use the right one!
Seriously, as simple as it sounds, using the right tool for the job and placing yourself and the device well (and getting it lit up well) gets you
really far along towards success.
Something it'd be nice to know in advance is if we're soldering onto the drivers or using those cursed faston connectors. OK..they aren't that bad but...

If we're crimping on faston's, I probably could make sure I round up about 4 or so decent crimpers so we avoid the flat mash 'em style ones.
And if we're soldering onto the tabs of the drivers....heat control!! Can't stress enough that too much heat can be a be problem there. You can cause the tensile lead going down to the driver (of a cone driver) to come off! You're soldering on one side of a tab and that lead is on the other end of it. Something over on that side to act as a heatsink is a really good if not manditory idea. Doesn't have to be a formal fancy heatsink clip....just something used
gently to drain away heat. Gently cause those tensile leads are highly flexible by design and
fragile.
The officials will be along to clear this stuff up...but thought I'd throw out a few things that come from experience as thought starters.
