I would like to know more about that CNC router setup.
Finally decided not to go for the front vented design due to the larger dimensions. Has now normal backport with plastic tube. The CNC router is a cheap China 6040Z-S65 model with some minor modifications (USB control interface).
I recently joined a makerspace that has a large CNC router. What program did you use to make the CAD file? Was it difficult? is it something that is downloadable/shareable?
Thanks in advance!
Very, very awesome looking speakers!!!
Great build. I enjoyed your photo journal of your process. How/where did you mount your crossover board?
You mention `easy to duplicate’. Please let me know if you would be prepared to cut a second pair? I am building an amp and eying this speaker design, but am lousy at making anything look nice!
cheers
