it stopped working, I had it living in a 1x12 cab and it stopped working wasn't the jack, connection, amp, or cable. I'm pretty bummed, and I bought it second hand, anyone know someone who can fix this guy in the Bellingham/Seattle area? Or if it's worth it I could ship it
\:huh

If you have a multimeter check with speaker with it on the ohm setting. You chould get about 6 ohms if it's an 8 ohm speaker. If you get this reading, check your wires again.

If all else fails, call Condor Electronics in Seattle. Not sure if they do reconing but they probably know who does.

I think I was your 10000th post, I'm honored. Thanks, I measured and was reading 0 ohms, I'll give them a call, and see what they say, I'm not sure what they do on a re-cone, what exactly is that?

Re-coning is replacing the cone (usually paper) in a speaker... but that's now irrelevant for you - you've got a shorted voice coil (0 ohms), unless you have a short somewhere else in the wiring?? Are you disconnecting the speaker leads and measuring at the tabs?

Reconing involves replacing the voice coil as well.

If the speaker reads 0 ohms another overlooked point of failure is the braided flexible wire that goes from the cone to the speaker terminals.

On more than 1 occasion in the past 40 years I have seen a detached wire, and or bad solder joint where the wire attaches to the terminals.

Worth a peek anyway.

I lived in Seattle a while back and used a company called "Around the Sound" for reconing...they did the work themselves and were factory authorized for many brands. Can't remember if Celestion was one of em tho!

What amp were you using with it? Generally when you get a 0 ohm reading, the voice coil is shorted OR one of the wires came off the back of the speaker tab (cut, broken, whatever) where you can't see it.

You'll probably have to remove the speaker from the cab to see a cut/broken wire from the back of the speaker tab to the cone, though, unless you use a compact mirror and a flashlight to look.

Good luck, either way.

If the wires fell off or broke, you'd read an OPEN, or infinity.. 0 ohms is a short.

We tried it from the tabs and the jack, no go, tried another speaker through the jack and it was good, so it must be the voice coil, I just can't get to it an don't want to destroy the speaker

If there was one wire disconnected from the back of the tabs you'd still get a 0 reading on your multimeter if you measured from the tabs, because there aren't two wires hooked up to the tabs, hence no way to measure properly.

That's why you need to take the speaker out and take a look. This is the area you'll be looking at.

I will look at the speaker again but I dont think it was disconnected, that would be an easier fix but I'll see tonight. I'm thinking it is the voice coil, maybe I'll just get one of yours, I'm greenback lover but wanted something with lots of headroom and tone

I don't think its the speaker, I've never seen one read 0 ohms blown or not. What kind of meter are you using? Is it digital?

All of my digital meters read "0" on both dead shorts or open circuits.

I use the continuity test on speakers. Then you know for sure if its an open coil or shorted coil.

Yes, they are(or were) good. They did an old Silver for me.

My meters read "0" for dead short, "OL" for anything higher than the range the meter is set to... including open.

Thats what I'm sayin! Never used one that reads the same open or shorted.

mine too! what the hell good is a meter that can't tell the difference between dead short and the opposite of dead short, an open circuit?
