A project pictorial: To fix a dead "subwoofer" speaker.
This was tossed by a neighbor, figured I could fix it.
First thing was to pull out the DMM and check it for continuity and resistance. It Ohm'd out ok, so that was good. But, I heard something rattling around in there...ah..damn kids...
It's cheap RCA HTIB shit, all glued up particle board and plastic, but I found an entry point. Snapped off the speaker 'cover' with a stout knife and then could unscrew the speaker itself. Yuppers, the dome had been pushed in and a foreign object had been pushed down the bass tube. Yay...SMH.
The creepy offending object with MiniVolt mod and Mini Vengence tank for scale.
Weird little toy thing, it's really heavy plastic for it's size. Wonder if it has lead paint? Eeep.
Used a small safety pin to carefully pull out the cone, then some glue stick to fill the pinhole and strengthen the smooshed cone somewhat. Should be fine, this ain't a Hi-Fi bit of kit.
I'll let the glue dry awhile and test it later.
*EDIT*
It works! Using as a bassy-ish center channel for my LR stereo.
A crappy recording with the main speakers turned off, using the FM tuner, and via cell phone.
I'm pleased it works.
