The passive radiator jig is finally complete!
This was one of those milestones that feels great to finish… right up until you realize the next step involves putting a router to a cabinet that has already consumed countless hours of work.
The jig is built, tested, and ready to go. Now comes the part I’ve been dreading: cutting the large openings for the dual side-firing passive radiators. One mistake here means a lot more than filling a hole and trying again.
In this video, I walk through the completed jig, why I designed it the way I did, and what’s next as this 3-way loudspeaker project continues to take shape.
Next up:
• Routering the passive radiator openings
• Building the beauty rings
• Finishing the side panels for the upper enclosure
• Moving one step closer to final assembly
Thanks for following along on the journey!
