Sub makes popping noises?

[myjaja 10+ year member]

Well, i just noticed that my new 12" aq hdc4 makes a popping noise on some songs. Its in a 12" pro box around 2.75 cu ft before displacement, tuned to around 40 hz and on an aq 2200 at .5 ohm. The sub is facing towards the cabin if that makes a difference. I had the aq hdc3 in that box before and I dont remember hearing those popping noises. Oh and the clipping light just barely flashes. So what could be making it do this? thanks

so i should call up audioque? Its under warrenty after all. Also, it only does that when i start turning it up. Im not saying to where its extremely loud, just to the point its a little under half way and up.

lol just wondering, pm him about what? Does he work for aq or something?

oh another thing if this helps. The sub gets loud, but you can hear that popping sound in the background. You can hear it more on the higher frequencies. I dont know if that changes anything or not. So does that still sound like the voice coil is out of alignment?

i dont work for aq. what it means is when a sub is overpushed passed the spiders capability the coil can rock and hit the pole.

you may just have a air leak check the screws holdin in the sub. if tight take the sub out and freeair and listen...

I have one screw that just keeps on spinning but other than that, the sub is nice and tight. I dont see how im over pushing it since it can handle 2000 watts rms and im giving it just that. Which the old hdc3 was only rated 1000 watts rms and I was giving it double that without any problems. Ill try taking out the sub and try the free air.

Okay I took it out of the box today and freeaired it. It sounded fine until I reached a certain volume. I didnt turn it up a lot because its out of the box and all but after I reached that certain volume, it started to pop. I also noticed a scratch on the voice coil.

Id box it back up and send it in for warranty/replacement

I called them up and they told me to keep using it until it breaks in and if it still does it, theyll recone it for me.

Also, would it effect anything having that deep scratch on the voice coil?
