Utilize custom components and make a portable system that can be used to traveling. Able to be tossed around a bit without worry.
Drivers from the Blast Box kit:
For the 3-inch drivers, I purchased these for the mesh part of the grill. Then designed the outer plastic ring to be perfectly flush:

This is the adhesive I used for the edge protectors:
I used a block plane to smooth the joints. After sanding, I did two coats of spray poly to seal the box, then used Rust-oleum 2x Ultra Cover Utlra Matte Black spray paint. Sand in between poly layers with an orbital sander, and use steel wool between dried layers of the spray paint to ensure the finish is smooth with no swirls or imperfections.

Tips & Tricks:
If you have a 3d printer, you can print the speaker grill components in PLA+ or most other tougher materials. I have uploaded them to Thingiverse and they are free to download. Will post links soon, but they can be found by searching “Blast Box”.
This was a very fun project. It was partially inspired from some other builds on here, but I added some of my own twists. I designed the speaker grills for the 3-inch drivers, the subwoofer, and passive radiator. I searched forever to find the best options, but nothing seemed to fit as well as I’d like, so I designed my own speaker grills that can be 3d printed.
