1. NEVER pour kerosene or any solvent on a speaker cone! The solvent will weaken the cone fibres and result in a driver that loses it's homogeneity and will not respond the same way after that, will not match a similar driver in the same or paired cabinet. Also some cone-voice coil joints could soften when exposed even to solvent fumes. Try a hair drier and be patient. You may have to cut off the dust cap, a cm from where it is glued to the cone, and then use heat and sharp tool to work the glue and remaineder of the dust cap free. I cannot repeat this enough: Do NOT pour kerosene or any solvent on the cone!
Pardon my ignorance on speaker basics - would like a tiny direction for my problem. I bought a 8inch 50 watt woofer (not sub woofer) about 15 years back, used it for few hours and it sounded good. I opened it today and connected it to my amplifier and it outputs too little volume. I gently pushed the cone and spider up, and the volume goes up and it vibrates well. How can I fix it? The spider feels hard... the soft rubber on the outer edge of the cone is soft/flexible...
Interesting to watch but for a how-to video it could really use some narration. At the very least, a few more titles to explain details like: what resistance measures should we get when checking with the ohmmeter, what are the little orange squares of tape and what are they for, etc.
If the kerosene destroys the original glue then why doesn’t it destroy the new glue. You didn’t clean the saturated kerosene off of the cone so will the new glue adhere for long. What is the purpose of the orange stickers, maybe you couldn’t see your original coil depth markings?
coil also attached from down side to spider how apply glue there, u didnt show in video.ita tricky and difficult part. remove or apply glue to sipder with cone.

This the most explained video Ive seen so far. Thanks
ang galing mong gumawa sir, malinis.
Luckily I got some kerosene leftover from my 747 :D
thank you. you mentioned that 1/3 of the coil should go into the magnet hole. does this apply to all speaker sizes?

The abswer is 15 years, if it wasnt used from what i can assume it probably just died, because its better to use them than leave them sit for so long
Is there a way to do this if the cone doesnt have a removable center cap? Gotta tear the whole cone out and do it that way?

4 or 8 or 16 Ω
The orange tape are for the deep and for the centric justage of the coil.
Thanks for the video. But how is that 1/3 because it looks like the larger part of the coil is the one going into the magnet. Clarify.
Where do you get the voice coils from and do they dual voice for any size sub
Thank you
Been looking myself, they sell some common size voice coil parts on ebay for cheap.
Is it okay to use hot glue, it is faster to dried
@@issactian3143 No..the coil can heat when playing.

Good next video how to make a voice coil for a 10" sub
Good thanks❤
Can I use diesel instead of kerosene for removing the glue?
kerosene is same as diesel

Clean it with strong alcohol. Use epoxy.
Excellent video, thank you!
What's the name of the glue used?
Thank you

Thanks 🙏🙏🙏
Nice video
How to select coil

12MINUTES OR 12H??????
Spider not glued
Doesn't need to be glued because it is glued with the cone
Wow
💋👋
Hallo vai
.
P
just buy a new speaker jeez
Hahaha
The speaker I’m repairing is 800 bucks the voice coil is fairly cheap
