So I turned on my Z Wreck and forget to plug the cable into the guitar. It didn’t put the amp standby like I know I should. So it makes a great big noise. I get it plugged in and play a few notes and it cuts completely out. I put it on standby and check all the normal stuff. Comes back on and cuts off again. So I change the cable, nothing. Change the guitar, nothing. Change the speaker, BINGO! Could I blown a 50 watt speaker with a 30 watt amp? This is a used Z Wreck combo from 2015. Brand new 6n14n quad of tubes three weeks ago. I put another gold in that was in another cabinet I had. Now all is well. I don’t know what to do with a speaker that works intermittently. Could this be reconed? Any advice is much appreciated.

Check the speaker’s resistance with a multimeter. If it is open, then it’s toast. I really don’t see that being the case thought by plugging into the guitar while hot. I do that all the time.

That's a shame. Glad you had a spare to tide you over. I was going to suggest testing the impedance for open or short but if the problem is intermittent, that probably won't tell you much. Weber used to do re-cones but that was many years ago and I don't know if they still do. I assume that it's possible to blow any speaker by overpowering its rating or just having an internal component go bad. Good luck.

I'd be really surprised if the speaker was blown by that unless the amp was set really, really loud. It's more likely that a spade connector was loose.

Spade connections are good. Thanks guys.

Bill, if you don't have a multimeter take a 9 volt battery and put the speaker connector across it for just a quick second. It should make a loud pop. If you put 9 volts across an 8 ohm speaker it translates to 10-1/8 watts, so you won't harm the speaker that way. You could use a flashlight battery if you're worried about it.

And, of course, you can try that speaker with another amp to see if it still fails.

After further review, the speaker is blown. I hooked it up to another amp, no sound. I’m going to send it to Weber speakers. They have a repair service. Thanks for all your help and suggestions.

Why yes, I do believe it is possible. I blew a brand new one, and it's the only speaker I've ever blown up. Still don't know why. I was running a 20watt head when it happened. Celestion's customer service was great and they send me a brand new one under warranty.

So last week I was playing my Z Wreck combo with another Gold. I had the volume on noon and the guitar on about 3, with occasional blasts of full volume for a few seconds, what a glorious sound it is, was. Yep, I blew another Gold. It goes from cutting out to completely cutting off and then the speaker died. RIP LOL.
Don, Z Repair, said that Golds get blown so I guess it isn’t just me. I sent the first Gold to Weber Speakers for reconing. I will send the other one when the repaired speaker comes back. I got one more older Gold that has low power use, ( Maz 8, Maz 18) that I can try. Wish me luck.

Wow, that's a drag. I thought that I was safe with the same amp/speaker. Guess not!

I’m confused. The Gold is rated at 50w nominal, the Z Wreck at 30w. Now, I know the amp may exceed its nominal rating, and the speaker could be less than its rating, but I’m amazed a 30w amp could blow a 50w speaker absent a defect in the speaker or some other oddity. I think I’d be contacting Celestion about this.

I’d guess that the gold has less margin at that number than most of Celestions. As you probably know, the amp can deliver far more power than its rating. That number is a nominal pre-distortion number. That can even be below _audible_ distortion. Speakers are similarly rated- allowing, typically, some headroom above the rating.
Some things that can damage speakers 🔊 beyond expectations are hard transients, digital distortion (pushing square waves at high frequency,) and exposure above the capacity of the speaker- above margin. Sometimes, people like hearing “speaker distortion”- this generally means overstress that will contribute to the early demise of that speaker.

Bill, I'd be really surprised if Celestion says anything except "You exceeded the power capacity of the loudspeaker"... It'll be interesting to hear what they say.

I’ve had good luck with Celestion on two occasions! Hope for the best!!!

Katherine Moore was the ladies name at Celestion. She was in the US office. Super nice. Even sent me a free Celestion T shirt.

I am interested in where this goes. I don't understand how two speakers can be blown with this set up.

Are your speaker tabs the slide on spades or soldered? I wonder if intermittent signal could be causing the voice coil to react adversely and self destruct.

That's a great point. Years ago I had an amp that was making strange noises, almost a harmonic sound; kind of indescribable. It turned out to be a dirty and pretty loose spade connector. Lesson learned! Now when ever I swap a speaker out I take a second and use needle nose pliers to lightly crimp the connectors so they're good and tight.

Update! I got my Celestion Gold back from Weber Speakers. They said it was the coil that was the problem. They are going to double check on speaker number 2. I’m breaking the speaker in now. It’s not too stiff, which is surprising. Thanks everyone for their input and help.

This has been an interesting thread. Glad to hear you got if fixed. After it breaks in , let us know if you think there's a difference between the tone of the OEM cone, and the new one.
Also, did Celestion ever get back to you ??

Also, did Celestion ever get back to you ?? I heard back from Dr. Decibel. We were going back and forth with emails. I sent one to him about the coil. He thought it might be the wires to and from the coil.

Hmmm, kinda sounds like they weren't all that much help.
Wow. What an informative thread. I had no idea one of Celestion's flagship ($320) speakers could be ruined so easily.
