Good evening, I wanted to share my silly project about making two speakers from stuff I had lying around / was gifted to me
All the information relative to this are well written and illustrated on my blog https://www.mimifactory.com/, otherwise this post would've become too long.
A friend gifted me some old car speakers, instead of throwing them away. Plus I got some broken panasonic speakers that I had laying around for a while.
It was quite simple taking the plastic cover away, but then i realized there was no hole for the tweeter and there were two big open slots, that I had to cover if I wanted to make an enclosed loudspeaker.
I drilled a hole with a hole saw but it was too big so I had to 3D print a gasket lol
And make two wood pieces by hand to fill the two big slots.
Capacitor in series with the small speaker = high pass filter kinda
Disconnected central coil from second speaker otherwise I had too many highs
Glued everything, filled with silicone, covered the outer silver parts with some wood grain texture adhesive, and then made a front cover mesh from unused wood and old cloth.
I am currently using them with the subwoofer unit of a LM1875 based 2.1 sound system that had its satellites missing.
I wouldn’t call this Hi-Fi, but it’s pleasant enough to allow me to not always use my headphones and have my hair always messy xD
Great for youtube, videocalls, etc. Basically free as well

+1 My kind of refurb!Looks 100% better than what you started out with. Might even sound that way too!

What happened to the Panasonic speakers? The tweeters from that set should provide better highs than a car coaxial speaker.
Trashed. Both coils of woofer and tweeter sadly were burned to a crisp, I opened them up to check.
It's ok though. Highs are good, thanks for the concern.

Only other things I'd suggest for quick and easy improvement would be placing a rigid cup chamber over/behind the coaxial4" on the inside lightly stuffed with damping, adding internal bracing, and stuffing the cabinets with damping material.
As is, you saved something and made something. I applaud your efforts!
