The battery mounting, that's quite clever making them a visual feature!

I just finished making this speaker. Used a different amplifier (a cheap $15 one from banggood, with a bit less soldering), and I'm really happy with the result. Fun project! I also used a slightly bigger driver (Dayton ND91 instead of ND65), and I added the DMA90-PR passive radiators.

5:47 Me: How do you get your speaker working so well? DIY Perks: I put the circuit boards in my plants. They bless them with the power of nature.

This project is super easy, barely an inconvenience

A video from you means happiness, motivation, learning for me. And it makes my day.
-
Amazing! It sounds exactly like my desktop speakers!
-
Didn't even get a notification. I felt in my heart you uploaded a video.

Welcome to another episode of "If I had these tools."

17:45 Very nicely done, and I could actually "hear the concrete" in a sense.

Always great to see a new vid from you

Some suggestions for the concrete. You could have added a little more water to the mix to make the mix more fluid. Also, try adding the concrete in lifts instead and tamping the concrete with a small round nosed rod. Lastly, feel free to remove from the mold at 24 hours. You'll need to keep the concrete moist to minimize shrinkage afterwards, so keep spraying the concrete with water for a day or two afterwards. The final product should be smooth and without any of those air pockets like you have in the video.

Most of Amplifiers from links in description are with single channel mode only - there will be no stereo. Check it 2 times before ordering! For stereo you will need 10 pin version. @DIYPerks it would be better if you add similar note next to the link. I almost bought mono version :)

Those removable powerbanks....awesome concept! you always impress us viewers!

Suggestion regarding pouring cement into molds. More than 40 years I had a job making "car size" concrete pipe using a wet cast process similar to what you're doing. We dipped a vibrating wand into the as-poured wet concrete, which really helped the concrete flow eliminating gaps and air pockets - it worked like magic! So, perhaps you could use a small rod attached to a cell phone vib motor or maybe an electric engraving tool .

When you said caulk, I thought you said cork.😂 it's the accent.

I've been watching a ton of DIY speaker building videos and I would have to say this video is one of my favorites because you explain everything and show the actual connections needed. Too many videos spend their time showing you how to build a box and leave the electronic guesswork up to the viewer. Thanks for not assuming the viewer is a engineer and explaining everything!

This man really doesn't deserve the dislikes he gets.
