I guess it's recone time.. What would cause this?

[CplCuddles]

Sub stopped working while playing, a couple days ago. Just today had time to finger out what was the deal. Blew out a tinsel apparently. Did I do this? If so, What did I do that would have caused this?  :help: :thankyou:

You were running this on the 7500 at what ohm? How’d you set your gain or did you?

4ohm so (2200W approx), -10db with a DD-1 & DSONanov3 o-scope.

Box specs? Looks like the leads straight ripped rather than burned even tho there are burn spots on the spider.

Almost at mechanical limits?.. excursion ripped some strands then the power/possible clipping burned the few that were left?

4ohm after rise to get the power u want u were prly clipping hard. Wire it to 1ohm and run clean power. It’s very hard to burn one of those tinsel leads unless heavy heavy clip. Manufacturing defects do happen but that looks like clip city

I think we have a winner

If that's the case, not just straight clipping... OP ought to inspect the rear of the surrounds really well where the cone overlays the surrounds.

I've seen the cone cut into the surround from the rear and actually cause failure eventually before without bottoming.

I'm ordering a recone kit, I'm gonna cut her open and inspect.

What ya'll think? Was I pushing her a little too hard? I "may"  :laugh:  have played some clean boosted stuff (djsnt, etc. ) Oops.

It appears to me, the main issue was the blown tinsel, although I apparently f'd my spider while I was at it. The coil is perfectly fine. How does clipping affect tinsel or spider? It would be the mechanical movement that would mess with it, yes? That burnt spot on the spider where the tinsel was intrigued me. Can someone explain what I have done? I'm trying to learn the ways, all ya'll are who I come to for learning.  :*******:   :spank:

Jeezus....you clipped that sub hard. Depending upon the box specs and tuning, COULD play a factor too.  I think you were beyond pushing it. Could have been a combination of things.

I never audibly heard clipping, nor did anyone else. That's not to say it DIDN'T, but the coil appears to be perfectly fine. I mainly play music in the 20s, it makes sense to me that I caused a mechanical death through over excursion.

That burn mark tho...could have been a lose connection. What size was your box and tuning?

That coil looks like charcoal! The coils should be shinny black not dull burnt black. Clippppppp city
