My old bookshelf speakers just didn’t cut it anymore… the bass was weak and the sound felt flat. So instead of buying new ones, I decided to do something completely crazy: build my own speakers shaped like a giant LEGO minifigure. 🧱🔊
But there was one rule: they had to BANG.
As a 90s rave kid who spent nights dancing at the legendary Love Parade in Berlin, I need serious bass. The kind you can feel, not just hear.
So here’s what I did 👇
I started with a set of full-range drivers rated down to 65 Hz… but that obviously wasn’t enough. To push the low end further, I added a huge passive radiator and tuned the speakers to around 60 Hz for extra punchy bass.
Then came the fun part.
Instead of a boring speaker box, I designed a custom LEGO-style minifigure enclosure in 3D software and printed all the parts on my brand-new Creality Spark X 3D printer. This super affordable entry-level printer even supports multi-color prints, which made it perfect for this crazy desktop audio project.
The best part?
I built the entire speaker system right on my desk — no workshop, no fancy tools.
And when I finally powered them on…
They absolutely blew my ears off.
Way louder, deeper, and better than I ever expected.
In this video you’ll see:
⚡ Designing a LEGO minifigure speaker
⚡ 3D printing the enclosure
⚡ Installing the drivers and passive radiator
⚡ The first insane bass test
Watch until the end to hear how they sound. 🔊🔥
Check out all the parts I used, including the 3D printer. It’s an affordable machine and did an amazing job printing all the components for this project.
