Killed my Deltalite 2512

Sorry to hear about the damage.

You forgot to say where you had the speaker-killing Enhance knob set. It's a huge bass boost.

The old Eden lead sleds easily put out double the RMS wattage peak--easily. The speaker's wattage rating is merely a thermal rating (wattage at which the voice coil melts)--what you need to know is what wattage will drive it to Xlim/Xdamage. It appears you found out the hard way, unfortunately. Did you hear any warning signs like farting or any distortion at all?

 

How old is the speaker? I think you should be able to get it replaced under warranty.

 

I'd call Eminence and tell them the circumstances.

 

Distortion effects will mask the speaker's cries for help (you can tell the difference with them), master dimed you were well past the clean "rms" power of the amp head. Too much amp power fried it.

 

Distortion masks speaker agony. Sorry for your loss.

 

Maybe it's just a tensile wire on the side of the cone slapping the side and can be fixed.

 

The Delta 12a will be tight and loud, you might find its not half bad.

 

There were two series of the 2512, the second (current) one having roughly twice the Xmax. It could be that someone was selling off stock of the old version.

 

You could take your speaker to Orange County Speaker Repair in Garden Grove. They can probably fix it.

 

Check that the wiring became loose and is touching the back of the cone before pulling the driver out completely.

I have a BE S12 that would rattle when pushed, one of the wires was a little loose/long and was buzzing by the rear port.

With tons of distortion you probably can't tell if the driver wasn't farting out, did you see the cone making large excursions?


It could also be that because of the midheavy tone the driver didn't make enough excursion to cool....when the cone moves the heat that's build up inside the "motor" will be pushed out through the hole in the center of the polepiece. That hole has a few purposes, prevent air compression between dustcap and polepiece and therefore lowering mechanical resistance (Qms gets higher), when designed right it may also lower harmonic distortion and last but not least the release of warm air inside the motor.

 

Check the cab - maybe something came loose. That said - distortion pedal?

When I read pre on 1/3, I was thinking on a passive Jazz using the bridge pickup, you probably weren't driving the preamp section very hard, so the master being dimed even with a little mid eq bump was probably ok. If however you were using an overdrive pedal - or any preamp before your Eden - then its possible you were feeding the preamp a hot signal turned hotter with eq bump. With the master dimed, your amp could have been clipping at 2-3x the rated rms power output for hours and you'd not hear it through the distortion.

How did the other cab handle the punishment?

Now again, could be something loose in the cab or something on the cone, but from your description it does sound like you killed it.
