Popping noise on my 12" type r subs


The subs are making that sound when the bottom out + when they reach full excursion be careful if it keeps happening eventually your subs will fail because you will end up damaging the subs voice coil.

Sounds like you've blown them.

When you were playing back to the friend, were you playing louder than usual?

Was the old box ported, and the new one sealed? The lack of ventilation may have caused the blow...

MTX 12'' sub noise


Sounds like your sub is overextending itself, and possibly losing contact at the voice coil. Overextending will make a weird rattling sound, losing contact at the voice coil will make a popping sound.

Blown?


Typically you will hear a popping sound when the bass hits, or you may not have any sound at all.......If the sub sounds good then your ok.

On a side note, pulling on the cone while the sub is in operation can damage the unit because it cannot move freely under load

Rockford sub squeaks


Hello markwasicki,

You did not specify what type of enclosure the subs are in or if they share the same airspace. But the sound you describe sounds suspiciously like the enclosure is at fault and not the sub itself.

Remove and reverse the subs in the box and test for the noise again. If the noise is still produced on the same side of the box, it's the enclosure. If the noise follows the sub, then you have a problem with that sub.

If the box is making the noise, and it's a ported box, you probably have "port noise". If it's a sealed enclosure, you could have either an air leak or flexing noise. In either case, repair the enclosure or put the subs in a new one. If the sub itself is making the noise, there probably isn't much you can do. Most likely some part of the voice coil assembly is touching where it should not.

Hope this helps.

12W3V2-D4 ENCLOSURE???


They need 1.4-1.7 cubic ft per sub(ported box) less if it is sealed but I wouldn't recommend that, it sounds like ****. Google "Re audio box calculator" and use it to adjust your dementions to your application

What size is the enclosure?
Sealed or ported?
