Wow, excellent work. They look way better than the originals. Glad you enjoy them!

Wow that's going to look awesome in oak. I'll upload a .3mf for you :)

Instructables doesn't support 3mf for some reason, but I uploaded them to the Thingiverse link. Can't wait to see them finished!

Yeah, the concrete can be tricky. It definitely wants to go everywhere. Thanks to your advice I have uploaded new versions of the front baffle and trim ring, as well as an stl of the walls, so that others can do the same as you and forego concrete altogether. You're right, I had that file sitting around anyway and never thought of the possibility of printing it exactly! I'd recommend a fairly dense infill and one of the stiffer materials such as wood filled or fiber filled filament, but regular old PLA may sound great as well. Hope the rest goes smoothly!

Oh, thank you for reminding me that I forgot a detail! I decided to file down the corners of the speaker drivers to reduce their radius a bit. Didn’t have to do much, just about down to where the “cone” for the screws starts. This was ultimately to make the bezel as small as I could get it but admittedly would probably have been smarter to just increase the size of the bezel a bit. If you don’t mind waiting a day or so I can upload a corrected stl and larger baffle so that you don’t have to dremel the corners of the driver. Or go ahead and file down the driver corners like I did :)

The KAB amp is great as well, I’ve used it in a few projects before. I don’t think you’d be disappointed with the Lepai, but no one ever complained about more power :)Good luck and let me know if you run into any issues! Can’t wait to see how they turn out.

Woah, that’s awesome. Had no idea that was a thing! I was planning on experimenting with a vibration table next but I’ll have to try this out too.

Awesome, enjoy! I use a Schiit Modi 3 DAC and a Lepai 2020A+ amp. Both are very affordable but there are even cheaper and still good DAC options if you look around.

Thank you!

Thanks!

Yes, I was a bit worried about having relatively thin walls with the concrete. The 50/50 ratio of playground sand is stronger than I expected though. If I have problems in the future I'll definitely be experimenting with some glass fiber reinforcement.

Yes absolutely! They’re meant to be hooked up to an amplifier/receiver just like a normal “old school” pair of speakers.

Agreed, they’re too cute lol. Big fan of your ‘ibles btw!

Thank you!

Thank you! I really appreciate the kind words. I think my next speaker build may be a hybrid MDF or plywood box with a 3D pritned front baffle and integrated vent tube so I can still easily get a very complex geometry and precise port length. Maybe that will be the best of both worlds.

It’s a Parts Express product. They’ve since replaced the version I have with a very similar class D version, both sound great for the price.

Thank you!
