Ok i built my own box and didnt do that hot of a job on cutting out the hole for the sub. Its not perfectly round and theres a part of the sub where 2 of the screws are pretty close to the edge. I pulled the sub out and readjusted it and managed to get all of them to tighten down pretty good except for one. It went in but it doesnt really get tight it just spins.
So my question is this the symptom of a not perfectly sealed sub??
if so does having one screw not tighten down all the way really cause all this noise? reason i ask is because i don't always get that only with the low notes and higher volumes.
also how can i fix this?? i'd hate to build another box.
that sounds like a leaky box AND your gains are turned up to high...can you add a second layer to the baffle and recut the hole smaller? Is the rest of the box tight?

god that almost sounds like a blown sub. one screw hole with a screw in it should not be making that much noise. i would cut a ring to mount on top of the hole you have now that fits tighter to your sub and is large enough to screw down to the current box. use weather stripping. also check the edges where the panels meet. did you seal your box? what did you use to secure it while the glue dried? screws? nails? staples? nothing?

When i built it i laid down some wood glue and just screwed it together as i don't have clamps and after that i laid down more wood glue at the seams. and after it dried i checked the seams again i put down more glue where ever it seemed thin. same with the outside....and i also bondo'd some on the outside.
i also set my gains with a DMM. Im using a Profile AP1200 amp. Its "rated" at 600x1 @ 4ohms. but when i tried to set it the gain knob maxed out at 42v and i need 48v. so i backed it down to 38....is something not right here?
Man that video made me cringe... That box is leaky... but it sounds as tho its clipping as well... Try cheap things first... But make sure you drop your gains down before you toast that sub, just incase its clipping
1. Try to seal the sub with weather stripping...
2. Make a top baffle w/ a tighter hole, which will also add to the strength of the box...
3. Rebuild the box
After listening to the videos I'm going to have to side with the majority and say that the sub is toast. It sounds like it bottomed out and bent the former - what you hear is the former, coil, or both rubbing in the gap. I doubt clipping could ever sound that bad.
What kind of box are you running it in (sealed, ported)? Also, how much air was able to get past the gasket when the screw was missing? It sounds like the sub was given the chance to unload and it did so.
If you're running a ported enclosure that's either tuned high or designed incorrectly (hey, it happens), you will see huge excursions below your tuning frequency with relatively little power.
What series sub are you running? Then again, I have no idea what kind of clearances ED subs have anyway.
Take the sub out of the box and run it free air. You don't have to use much power at all. If it's still making the noise then it's most likely the bent former I was talking about. I was able to hook my bottomed out a series to my HT receiver and it made the noise with very little power input.

Well heres a photo of the baffle i made....a lot better theres no play when the sub is in.
Also here is a video i took of the sub after i pulled it out of the box...theres definitely no rubbing sound or indication of a blown VC.
After i took that i video i did notice 1 quarter inch tear and 3 other small tears on the spider. Right then i called eD and i believe i talked to Ben. he said those tears came from the over excursion....and that i definitely need to check my signal along with fixing any leaks on that box...im sure im just going to have to send my sub to eD.
Sad but true Roman. I thought i had it figured out...apparently i never even suspected my box, nor did i think it would play a roll in its demise.....rough way to learn.
not at the moment.....i kinda ruined the sub in a inopportune time, im unemployed right not so i have a lack of funds. i did call them... of course torn spiders void the warranty so its going to cost me about 90 bucks to fix....so i kinda have to wait till i either get a job or trip over a bag of money
