If you don't rebate the horn the cut out isn't critical but no way to get 'round the appearance of the vent.


I'm not going to recess the horn this time around, but next time I will. I'm thinking about making a jig or even trying to get some CNC time.

Cheap trick is to craft a really square vent box and get it glued on to the baffle before glue-up just right. Then, make the cut with a flush trim router bit. The vent box is your guide.



Thanks for the tip. I tried using the vent box as a guide for the jig saw. I really wish I knew this before doing it -- I would have picked up a flush trim bit for the job. I didn't want to use my spiral upcut bit for fear of taking too many chunks out of the vent itself. I bought a router specifically for this project so I'm not too experienced with it and have a sparse bit selection.
