JEMT8 Posted October 3, 2010 Report Share Posted October 3, 2010 (edited) So one of my subs is creating what I can only describe as what sounds like a plastic bag rattling. This happens at lower frequencies. For example, in the song 'Pop The Trunk" by Yelawolf. During the kicks and the higher parts of the bassline there is now rattle but there is during that low note. When I push down on the cone, it moves freely and I hear no scraping at all. The sub doesn't get hot and it seems to be keeping up with the other one. EDIT: The sound is very quiet and not noticeable until you get right next to it. Any ideas? The subs are Sa-12s. The only difference I noticed is on the one that is making the noise, the dust cap looks to be a tad off center. I tried taking a pic of it but they don't show it very well. Thanks for reading!

Robert8252 Posted October 3, 2010 Report Share Posted October 3, 2010 Playing below your box tuning. Wires slapping inside the box?

JEMT8 Posted October 3, 2010 Author Report Share Posted October 3, 2010 Playing below your box tuning. Wires slapping inside the box? Tuned between 33-34hz. And would it affect only one sub? Doesnt sound like wires slapping. I put my ear up to the sub and it's definitely coming from there. Quote formerly known as Jaylor Swift Link to comment Share on other sites More sharing options...
Robert8252 Posted October 3, 2010 Report Share Posted October 3, 2010 Get a hold of Jacob. Ok assuming these are new subs? I forget if you said so or not. I know the box is new though.

JEMT8 Posted October 3, 2010 Author Report Share Posted October 3, 2010 Get a hold of Jacob. Ok assuming these are new subs? I forget if you said so or not. I know the box is new though. Well basically brand new. I had ran them both for a few weeks and then sold the box they were in and just ran a single one until i got the new box. The one that's making the noise was the one NOT in use for a couple weeks. Quote formerly known as Jaylor Swift Link to comment Share on other sites More sharing options...

JEMT8 Posted October 3, 2010 Author Report Share Posted October 3, 2010 its the coil recone time Awww shucks. This makes me sadfaced. Maybe I'll just sell them on craiglist and get a pair with D4 coils instead of D2. Quote formerly known as Jaylor Swift Link to comment Share on other sites More sharing options...
JEMT8 Posted October 4, 2010 Author Report Share Posted October 4, 2010 its the coil recone time Hmm. I was actually thinking about this. The sounds is very quiet and barely noticeable unless you get right next to it. Quote formerly known as Jaylor Swift Link to comment Share on other sites More sharing options...
JEMT8 Posted October 4, 2010 Author Report Share Posted October 4, 2010 (edited) Well pulled the sub out today to check the coils and wouldn't you know one of the screws was stripped and was making and air leak. I checked the coils anyway and they are good. So problem solved. no more noise after i put it back in Edited October 4, 2010 by Rolladoedoe Quote formerly known as Jaylor Swift Link to comment Share on other sites More sharing options...
