There used to be several vendors, from pennies to round dollars. Checked ebay and did not find any. WHAT ? Checked Ali and nothing. WHAT ? Checked MCM , nothing, What ? Every store wants to sell whole speakers at 20 times profit price plus robbery shipping.
I do not want to throw away a humble speaker. Where to get the coil ?

 

Really, good luck with that. Try here for a affordable replacement speaker, they do have some speaker repair parts. https://www.parts-express.com/

 

Selling voice coil replacements was probably a reasonable business a few decades ago when there were only a few manufacturers, and speakers were really expensive.

 

Any chance you could rewind the coil?

 

I've never heard of, or seen, a replacement "Voice-Coil" only, for any Speaker.

Relatively inexpensive Speakers were never designed with Voice-Coil replacement in mind,
that's one of the reasons why they're inexpensive in the first place,
however, some very popular Speaker-Models have complete "Re-Cone-Kits" available.

"Eminence" Speakers are a solid low-budget bet,
they also make some very respectable high-end products.

Many "real" "Pro-Audio-Speakers" ( ~$300-plus each ), are specifically designed for
a relatively simple, and relatively fast, Re-Coning-procedure.
( I've Re-Coned many "Gauss-Cetek" 15s that were heavily abused every night back in the late '70's )

If You trashed a Voice-Coil,
You probably need to use a higher quality Speaker,
and/or,
You also need ............................

To use a Properly designed Cabinet, ( most commercially-available-Cabinets are Garbage-Designs ),
The Cabinet must be matched to the chosen Speaker,
or at the very least, the Speaker must be matched to the Cabinet

More-Drivers, and/or, more-Cabinets,
( the specific physical-arrangement of multiple-cabinets is always critical )

More thoughtful Cabinet-Placement in the Room,
with all similar-Cabinets clustered tightly together into groups, preferably vertically oriented,
This has a definite impact on Power-Handling capability.

EQ / Low-Cut-Roll-Off at a higher Frequency, and/or, a Frequency better matched to the Cabinet-Design,

A DJ who's not an idiot, and can be trusted,

Replacements for Blown-Speakers comes out of DJs Pay,

Death-Penalty for touching the EQs once correctly set by the System-Engineer !!!!!!

Any chance you could rewind the coil?

Not with my now shaking hands and degrading vision.

 

If they match specs of the speaker, make sure your cross over isn’t damaged should you proceed.
