HDC3 18.....What does this sound like to you? (video attached)

[ferguson621]

I was playing my music yesterday and all of a sudden my hdc3 started making this rattling noise.....I used my dmm to set the gain on my amp so I know I'm not overpowering the sub......I have attached a video so you can hear what I'm talking about......I was playing a 40hz test tone at quarter volume roughly........I just had it reconed from soundqubed about 2-3 weeks ago also.....I havent overpowered it at all either......Thank you for your input

coil seperated from the cone? or is it just set low

where does it sound like the noise is coming from

 

[ferguson621]

I didn't turn it up to loud because I was playing it free air.....so the volume was set low.....To me it sounds like it's coming from under the dust cap

it sounds a lot like the noise you hear where people intentionally wall socket subs, they'll spark and die or sometimes theyll make a nasty sound like that and it seems like the cone seperates from the coil

****, that's not good, see I hooked up a clarion eqs746 and when I would turn my car off it would thump, could that have anything to do with it?

i doubt it, shouldnt be enough to kill a sub with a coil large like that. im merely offering my opinion, it could be something else but theres nothing else visibly wrong with the sub from what i can see so i couldnt tell you.

it could also be the inside of the coil rubbing on the motor pole. there's gaps to see the coil in the video and the coil looks fine.. not sure what happened to cause it to make that noise

I didn't think so....and the thump only happened a few times cause I've been turning my head unit off before I shut my car off so it won't make that thump noise.......I do appreciate your opinion, thank you.....so do you think that'll be covered under warranty?.....the sub still plays perfectly fine even at high volume.....which is good in a sense because that tells me it's not blown, am I correct?.....thank you for your input

If it plays fine at high volume then I have no idea I'm completely confused. Never heard of something like that before

 

[ferguson621]

Does anyone else have any idea's as to what could be the problem? I've never experienced this before......and I hate not having bass lol, I'm feining for it ha

I would be looking at the amp at this point. Try swapping sub or amp out to narrow it down to the component. I'm guessing the problem is with the amp

 

[ferguson621]

That's a good idea lol, I have no clue why I didn't think of that lmao....I'll start by swapping with another sub and see what happens.....I'll post an update shortly

 

[ferguson621]

Ok, after a more detailed inspection I finally figured out what was wrong.....on the very edge of the spider on one side it came unglued just slightly causing it to slap against the basket....So my next question is....what type of epoxy or glue would you guys recommend for gluing it back together.....the part that came unglued is small enough to where I can just barely get my finger nail under it, so it's not much at all....but just enough to make that annoying noise....anyways, thank you for your input

CA glue (hobby store) or E6000 (walmart)

This ^ but be careful because CA glue will peel off layers of your skin before it comes off. Use gloves if it's your first time with it lol
