I built/renovated this insane boombox

I guess I have a thing for shoving loads of overkill electronic equipment into novelty boxes.

This time it’s an old boombox from 1986. I found it on the street in 2007, and have kept it ever since. While it was slowly dying at one point it served as a brilliant stereo distortion unit (sample pack of that here: https://e.pcloud.link/publink/show?code=kZnNlXZNP2fAPgNSQHRrKSj07GWHQ3gykaX).

Here’s what I did to it:

  • Gutted it of All internals, replaced with a 100W Bluetooth amplifier and a very beefy battery pack
  • Replaced the old 8W full range drivers with some 50W woofers, a pair of tweeters and a crossover at 4khz on each channel
  • Cut off the top of each speaker enclosure and added a plastic junction box on top to increase the cabinet volume
  • Designed and 3D printed a couple of transmission lines/bass ports, tuned to 45hz, mounted on top
  • connected speakers with (badly) coiled jack cables as they’re detachable

Here are the pics:

I finished it today and its utterly mad. Much louder than expected and the sound is great. Can’t wait to take it out for a road test on the weekend!.. And also I might build another one just for fun.

Update - I made a video:

Super cool! I’ve always wanted to nab a vintage boombox and use to mix in some subtle re-amping for mixing in with “lo-fi” (but really just fuzzed out) hip hop.

Everything i can find locally is stupid expensive for what it is, maybe i can check out eBay.

Since I’ve been thinking about doing another one I did peruse ebay a bit and there are loads on there.

Haha that’s a beaut! Also, don’t tempt me with your tat. I’m very susceptible to tat.

I love this so much. I am inspired. I think it’s time for some sort of boombox project.

I might have to get my crew back together, see if they’ve still got their grey and maroon nylon hooded jackets so we can practice a few windmills :grinning: those were the good old days

Cheers mate! And I hadn’t seen that until now - bloody genius. I’ll wait for my kid to grow out of her one and then I’ll commandeer it.

Here’s a little video I did recently to accompany an interview that’s going up on Blokas Labs’ website soon, breaking down the build in some more detail:

This thing is smart. You should get some impulse responses out of it! Maybe even get someone to create a VST version of it for those of us who would like to re-amp their sounds. :smiley:
