What is the best way to cut irregular polygons? I figured I would use a
template and a router but are there any online instructions that illustrate
the process? Maybe a book would be better.
What I need to do is to mount the something like the following into a 1/2" or
5/8 MDF panel so that the front of the speaker is flush with the surface.

Do you need to cut the hole first, then rabbet the outside?
I used an el-cheapo B&D jigsaw on some old speaker cabinets eons
ago to cut the holes for mounting the 12" speakers from my parents'
old console stereo, a real hack job.
Today, I'd probably use a trim router to do the cutout (after marking
the hole with the outline of the speaker) and use a router to cut the
rabbet (freehand) for the inlay, then drill the mounting holes after
it was seated in the new hole. Make sure to vacuum out ALL of the
sawdust or it might buzz later on. DAMHIKT

What i need to do is to mount that speaker with that unuasual shape so
that it is flush with the front of a panel. Not unlike doing an inlay.
I am unsure how to do about it with an odd shaped piece like that.

I thought that is what you might say. Yes, I have several holes to cut
like that. Thanks for the tips! Now I have to figure out how to make
that template.

drill or saw a round hole big enough for the back of the speaker to
hang through. position the speaker in the hole and trace around the
mounting flange. cut the line a bit with a sharp knife and carefully
rout almost to the line with a straight bit in the router. trim to the
line with a chisel.
if you have a lot of them to do make a template.

first do one in a test scrap. if you get a good fit, cut the routed
part all of the way through. this may be enough right there if you
will be using a top bearing bit to follow the template. if you'll be
using a bushing to follow the template you'll need to enlarge the hole
by the difference of radius of the bit and bushing.
be ready to make a few templates until you get one that fits well
enough for your needs.

I'd say the same way as regular polygons.
Are we talking about the same thing, or are you referring to compound
angles in an irregular polygon? ...a much more difficult proposition.
