Subwoofer diagnostic help.
Just curious to see if any of guys can help me out.
I have a 12" ED sub in the hidden C5 box... the box fell apart (bottom part seperated from the top) when I first put in the sub
and I had to take it out and put in new screws and I glued it together to make sure it is air tight...
My sub developed an odd buzzing sound... so I thought the box got another leak... so I took the sub out and made sure I had all the screws secure. I also took the box out and made sure it was air tight and it was...
Now the buzz is still there at moderately low to moderate levels... I contacted ED and they stated that I should take the sub out and see if the buzz is still there... and if it is I should send it back to them....
Is this a common way for the subs to fail by buzzing?!
Also what does an air leak sound like?!
Thanks,
Max

You can test by hooking up another speaker. It can be a stock speaker or cheap speaker. Test not for sound quality, but if it makes the buzz. Make sure you turn down the gains and volume first!
Side note - are you getting "Database Errors" on the forum?

Does a broken/leaking box sound like buzzing at all though? Also could not having the little felt layer between the woofer and the box be causing this?

It's hard to say .... not sure what you mean by "buzzing". A leaking box wouldn't make the speaker produce a buzzing sound. Is it possible you could be mistaking the buzzing sound for rattling/vibration at certain frequencies?
Also, If you don't have felt/carpet on the box, you do need a gasket inbetween the sub and box for a proper seal. Not sure if the noise could be coming from there as I've never mounted a sub without either.

Didn't help much ... if you're confident in the install and the amp, like spkrboy said, depending on how loud you were playing it, you could've overdriven the sub. You won't really know until you swap in a sub and test your setup independant of the suspect woofer.

The sound of an air leak is entirely dependent on the size of the leak. Leaks generally don't buzz, but damaged driver suspensions do.
Do as jc227 suggests and swap in another driver to be sure.

As soon as the box has substantial leakage, the sub becomes unloaded and easily damaged. Most subs need the air suspension the box provides in order to meet their power ratings. If you were playing at high volume at any time the box was damaged, it could have happened then.

A raspy buzzing at a specific frequency range is generally a sign of internal motor damage. (the moving parts are out of alignment) In rare instances, this is cause by overdriving a small sub.
