Rebuilding 10in speaker part 1

Rebuilding this old speaker i got for free.

It came with a blown voice coil, that's no wonder since it was only rated for 15 watts. Yes, you read it right. It was designed as a fullrange driver, so for it to reproduce the entire audible range a severe compromise in power handling was made. The wire of the original coil was very thin, more suited for a 4" midrange or tweeter than a 10" woofer. I put in a thicker wire since i intend to use it as a woofer, but still thin enough to not require substantial modifications and for it to have good sensitivity. I expect this new 4 ohm coil to handle around 40 rms, could have been more but i didn't have thin epoxy adhesive that i could apply with a brush, so i dipped the coil in lacquer instead.

yah for real. those things were designed to reproduce the full audio range and had very high sensitivity so high power handling wasn't a necessity, because they went quite loud without too much power. but of course we want more.

sorry for not updating this vid anymore, i have fixed this speaker, but it broke again during testing and i wasn't filming it... it sounded really good but i did one of the windings poorly and it rubbed on the magnet till it got cut. it'll get done some other day.

@bfx596 can't we all just get along and stop blowing speakers in the first place?

@bfx596 i know all about t/s parameters. probably more than you'll ever want to know yourself. this is why i did it just for fun, recoiling speakers as a serious job is impossible without high precision tools.
