I would consider a smaller bit more dangerous, Like I was using 1/4 inch dia downcut bit for cutting driver circles. The high frequency whine it was creating when cutting deeper, it felt like it would break at any time and these are like a flying bullet. I think any bit which can break easily is more dangerous(my opinion).
Used a 3/4 roundover and sanded it with a sander(80 grit) to make it rounder.
Back panel pending, will mount woofer crossover on Back panel. MTM and DIY crossover fixed and did a quick test. It is making music 🙂
I have put in 1 inch ceramic wool all around the MTM section.
Applied tung oil and dried for 2 days and applied wax over it with a hair dryer. Only thing I didn't like is that the sapwood turned out darker.

Update : Speakers are 95% complete. Assembly is complete.
1. Need to apply tung oil on the outside over a period.
2. My first impression - I love them, especially for Mid-Low response.
High and Mid are good, but bass needs some therapy. I am not an expert, so I don't know how to describe the issue I am experiencing, Bass is good and it is tight but it could be tighter with more punch, there is a vibration like bass signal has been stretched over time. At present bass section is only painted with liquid rubber with nothing else inside. I have used ceramic wool for High-Mid section, but I do not want to use that in bass section as it can disintegrate easily with high air pressure. I am going to try coconut coir door mat to treat bass section 🙂

Wow. What an accomplishment. That wood is stunning. In time, you will get all that you want out these speakers. They look to be well thought out, and it has been a long road.
If getting into the cabinet is relatively easy then you can start with pretty simple experiments with say maybe a pillow fit into that space inside. Not too big of course. A fibrous door mat may not do anything worthwhile.

Another idea - I often use polyester batting as a barier within the speaker box to contain and restrain loose fiber stuffing. Natural long fiber wool, shredded denim insulation, and mineral wool can migrate around the speaker box, and in some cases it can get into the voice coil.
Polyester batting is a non-woven felt like material. It is intended as a filler within quilts and blankets, or as an insulation liner within jackets. I use batting that is about 1/2 inch thick. A few staples is all that is needed to form a net to hold the loose fibers in place.
