What is causing me to blow speakers?

[Sputnik03]

I recently blew a couple speakers in two combos and a couple in two different cabs. Pretty pricey problem. A green beret, an et 65, an eminence 15, and an EV all bit the dust. It’s not like I’m a newbie either. I’m 49 and I’ve never blown speakers in my life, and suddenly I’ve blown 4. Could it be the power in my house? I do not have a brown box. My studio power conditioner shows I’m fluctuating between 116 & 117. The only thing that’s different is I recently had my main three amps serviced, and at the time I had speaker line outs that defeat the signal to the internal speaker installed in two of the combos. Is there something to test for or check for?

I don't even know where to look at your problem, but while I was reading about it, I kept getting google garbage add for womens make up, overlaying your post. These adds really aren't in my realm, I'm a 70 year old man. Just thought you'd like to know about this stupidity from gurgle.

We would not judge you for wearing makeup. At your age you earned the right to do whatever you darn well feel like.

That's really interesting. I always thought that way about speakers, too. I even had the thought that maybe i should just get a 200 watt speaker so I'll make sure not to blow it. But evidently that thinking isn't right. The tech told me with a 15 watt amp I'd be much more likely to blow a 75 watt speaker than a 20 watt speaker. Honestly, I don't understand it...

Only if the speaker was rated for 4 ohms and you use 16 ohms or more into it could you break a speaker that was rated 50% more in watts then what you could push into it.

Yes, I’m using speaker cables and not instrument cables.

I think you may have been responding to someone else as this isn't what I asked.

I recently blew a transformer in a tube amp. Now it sounds fine at low volumes, but when I push the amp, it farts out and the volume reduces. If the issue is your transformer, when you tried the next speaker, it would have sounded bad right away. But if it's the speaker, the speaker would have sounded fine for a bit before the 2nd one "blew out". Which was it? Did the next speaker sound fine on the same amp, then blow out like the first speaker on the same amp? Then it's probably the speaker. If the next speaker tried on the same amp head sounded bad right away, you might have a bad transformer.

Also, I don't know this was clear, but did the speakers go bad by going completely silent, or just some crackles you notice at low volumes? Maybe the tech also replaced tubes and it's your new preamp tubes going microphonic right away? If the speakers didn't go completely dead, a short video from your phone showing us what it sounds like would tell us a lot.

Did the speaker blow the amp, did the amp blow the speaker, if it were me I'd just push it all into the junk box and get a new amp and get back to playing guitar.
