C-Horn Project!

No I don't think so. Acrilic (Plexiglas) should be cut with Laser cutting machine which one of my friends have

Acrylic cuts beautifully with a CNC router.
It takes a pretty powerful laser (100 watts or so) to cut acrylic thicker than 3/8 or 1/2"
There are not many non-commercial lasers that can take a sheet of acrylic as large as this speaker.
A DIYer with a hand router can cut acrylic very nicely if he makes a 1/4 inch plywood temple to follow the contours.

I CNC machine acrylic quite often, the best you can use is a single flute-up-spiral.
Solid Carbide Spiral Plastic 'O' Flute Metric & Inch -ToolsToday.com- Industrial Quality Solid Carbide Bits

I sand from 220 > 800 > 1000, then buff.

Flame polishing is fast & nice, but will craze if any alcohol based liquid gets in contact with the edges. Laser is nice like Dennis mentioned (cuts & polishes the edges in at the same time).
