Having probs with Dcon

[Hookedup12 0]

I have a single Dcon 12 right now in a Starr mountain sound box tuned at 33hz (i know its not the box) and its on a Boston's acoustics gt2125 bridged for 400w but I got it tuned way down prob seeing a honest 200w if that and it has this buzzing noise right behind the dust cap almost like a rattle only on the higher notes (low notes you can't hear it) I have the lpf at 70hz I wonder if turning it down further will help but I've had it in two different boxes and its done the same way in each one and I can't seem to fig out what's going on It sounds as if I set a screw on top of the sub while it was playing.

the dustcap might not be glued down properly.

I also thought this I don't want to mess with it before I hear from ssa because I don't want to start messing with it an not be able to eat some kind of warranty or something. Would I be able to fix it with out completely taking the yay cap off? Possibly putting a bead all the way around the cap and letting sit to harden???

If it's simply a dustcap that's a little loose it wouldn't be worth the cost of shipping for warranty repair anyways.

Simple solution is to temporarily secure the dustcap (with tape, for example) and see if that fixes the problem. If it does then yes a bit of CA glue would fix the problem.

Good idea with tape. Ill try to tape it down Tomo and aside from the rattle it Sounds amazing. It gets so low.

If tape helps what would be better to use the ca glue or epoxy??

No if the tape works you can use some ca glue or epoxy which will hold/look better.

something like this would be best for cosmetic reasons.

Currently replying to your CA.com topic. Based on that topic, I worry that the Dcon was hammered on and over driven in the original enclosure that was not right for it, in addition, the new enclosure looks to have a ton of port. See if it is a loose dust cap first. Then follow up with my suggestions about free-air at low volume and checking the felt pad for markings from the leads.

He asked which would be better to use: epoxy, or ca glue.

That is not at all how I read it the first time.

Tried the glue and it did not help. Still making the noise I'm not exactly sure what to do about it. Nobody in the surrounding counties does recones so that's not an option. Any advice?

Pull the driver out of the enclosure, and check the felt pad on the back of the cone. You can also try lightly applying pressure on the cone, and see if you notice any scratching noise from the voice-coil rubbing.

This^ and play it at a low volume free air to see if you can identify what is making the noise.

I pressed down on it equal force all the way across and it feels smooth as a baby's bottom, I can't seem to catch a break and I don't wanna keep pulling it in an out of this box because I don't wanna put holes all around the mount and really get a leak or something if I pull it out of this box I won't put it back in until its perfect or I have a different sub because I don't want to run into messing this box up. I don't want to have to get another sub but I don't know what else to do I'm in a situation like I'm damned if I do and damned If I don't

I read through the thread on ca.com as well, and my thoughts are the same as yours are. Over driving the sub in a leaky sealed enclosure likely caused a break down in the suspension compliance. The new enclosure seems to have a tad bit more port area then required coupled with an enclosure on the large side(I think) for your application is allowing the sub to reach a mechanical limit that it shouldn't be achieving at this time. It could be simple "lead slap" but that is still a result of another underling issue more then likely.

Can you get any images of the felt pads on the back of the sub? Or perhaps a video or two to show the situation for what it is?
