DIY Horn Speakers - Step 6: Time to Make the doughnuts

 Cutting out the centers saves a lot of time at the lathe. I used a 2" fornster bit and used the screw hole from the circle jig as a center.  I cut out seven circles for each horn (up to the point where the the flare begins).  An added bonus--the 2" drill bit was perfectly matched for the 2" compression driver.  For the larger circles for the mouth of the horn, I ended up using the router to cut out the centers.
