Do you mean like regularly or just a one time thing if onetime thing your fine it shouldnt have messed it up. Buttoming out is your sub working passed its limits in the enclosure. I had a problem wit buttoming out before i tuned my box properly But you should be fine if it was a brief thing Its when you do it for a lil while and it heats up that the sub fails

bottoming out like the coil hitting the back plate? at 45hz that's 45 times a second, so that's quite a bit of banging metal on metal if you asked me.

It's bad if it keeps occuring, which it will if it happened once.

What equipment?

How'd u set gain?

What's the box specs?

What are ur amp/ hu settings?

norally take 1 time at high power to destroy the coil. is could also be ur spider hitting the top plate depending on basket/spider...

I had the same problem with my AQ HD3..or so i thought=P it turns out the noise was the voice coil hitting my dusk cap =( seems that the cone ripped off where the spider/coil meet with a cone. Was fun since i was heading to a competition=P

It certainly isn't good for the sub, realistically can do a good amount of damage if it bottoms out bad enough.

i st everything so it doesnt bottom out. it actually happened a couple times. but all the times combined it probaly equaled 1 second. when you here that noice it is pretty much instinct to turn it down . sounds good i dont think much happened if anything

pull the sub out and check it. Push down on it a little to see if it isn't doing anything it's not supposed to

You see all them white spots on the black spider??? Thats where the cone was hitting them. So if it didnt sound like it was "bottoming" out it was moving pretty good.I have first hand experience with the cone hitting the spider on my DDs but they have never broke like that.Just letting you know.
