Method I use with Autocad is to section the horn profile into 50 segments (I do this via a spreadsheet which generates an Autocad script, drawing the 50 segements automatically).
Using the osnap to centre, you can rotate groups of segments whilst keeping the centre of each segment together. Just a matter of selecting group of segents, rotating, select another group etc. Easier to do than describe!

I've been messing with it for a few hours.. And I've got this. Please remember it's my first time folding a horn.. so don't be too hard on me Is there anything horribly wrong with the way i've done this?
I haven't put a divider in the rear chamber yet.. I want to be able to adjust the rear volume after they're built.

There is a trade-off between the least folds possible and the most accurate contour possible.
You are using too much folds IMO, making response at the upper end worsen and making the cabinet more complicated to build.
I'd suggest a simple S-shaped fold like member mikee12345 is using:

Mike, just replied to your pm on PSW before seeing your post here..
Speaker is Beyma 12LX60. The areas below the baffle are also part of the back chamber, giving a volume around 30 litres (don't want to waste any space!
Before you say there is wasted space at rear corners, bottom corner is reserved for future power amp, and top corner is reserved for input connectors and future input preamp/crossover/processing
Cheers
