My 12 is flapping

[cleansoundzz 10+ year member]

I got a custom made 12 inch Atomic Apocalyse for my truck which is getting about 1200-1300 watts from my Arc Audio KS 1000.1 @ 2 ohms. However on certain songs when the bass hits hard the subwoofer flaps a little. At first I thought it was the grill that I had over the woofer. But when I took off the grill and turned the bass up a little, the subwoofer still flapped a little. It seems to me that the material on the cone is making the noise. What are your thoughts?

How do I fix that?

maybe your sub is fapping to the bass

Sealed box or ported?

If ported, it could just be noise from air rushing into/out of the port. If it's a sealed box...make sure it's a WELL sealed box and check for surround glue failure on the sub. A small air leak can sound like what you're describing.

This is it. The box itself is 2.3 cubes ported at 36hz. I love the bass but do not want to destroy the sub.

What kind of music do you listen to? Tuned kinda high for daily

 

[murph 10+ year member]

well if you are playing anything with notes 8-10 below tuning or lower the sub may be bottoming out.

check your box and see if it leaking air out the sides. i had a simuliar problem, was just missing a screw. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Yes check for leaking air... I doubt bottoming out but where are your gains set

 

[JerryEllis 10+ year member]

check where the surround and the cone are glued together... if the glue is barly holding on in some places it will make that noise on some notes... if that is the case all you have to do is add some glue to it and problem is fixed.. also check your dust cap
