Speaker Issue
« on: July 24, 2017, 11:07:33 PM »

So, I have a 15" coax speaker that doesn't work. I hook up a 9 volt to the woofer, and nothing happens. I get a click when I hook it to the tweeter. No obvious damage anywhere.

This is the back of the speaker:



(If the picture doesn't work, it is a DRS L15CX450 Coaxial Loudspeaker. 8 ohms, 450 watts.)

Any idea if it's fixable? Or where I can get a replacement?

Thanks!

Can you hook a multi-meter to it?  Does it register anything?  Or an open circuit?  Can you move the cone by pressing it?  Have the tinsel leads going to the cone torn off?

One way or another you'll most likely have to get it reconed.

With a multi-meter, it shows an open circuit.

The cone moves, but not cleanly. It sounds like a bit of a metallic scraping noise?

I don't know what you mean by the tinsel leads. All of the wires look normal...

Thanks!

Coil's melted and let go. You'll need to get it reconed.
The scraping noise is the noise of the coil's windings scraping against the magnetic structure. Not good.

So getting it reconed will fix it or will I just have to replace the whole speaker?

Thanks!

Recone should fix it up - it replaces all the "soft" parts - cone, coil, etc etc, so the low-frequency section will be like new.
