Does Polyfil really help?

Bronze Member Username: Strike5858Post Number: 20 Registered: Mar-07 | Ok iv heard that adding polyfil to your box helps deaden it and trick the sub into thinking it has more airspace. This dont make sense to me considering that if you add that stuff to the inside, it will take up airspace. Also if it does, how to you put it in? adhere it to the inside of the walls of the box or just stuff it in? |

I'm guessing that makes them take longer to get to the other sides of the box so it makes the sub act like it's in a bigger box but I'm not really sure. I think you can just stuff it in to a sealed enclosure, maybe keeping it a little bit away from the sub, but in a ported enclosure you have to staple it down to stop it from blowing out. You could probably use netting or something to hold it down too. |

You can always try some and remove it if you don't like it. The specs on my subs say to staple 1" of polyfil to the box walls. Not really sure if I should do that or not though. Here is a little more info. http://web.archive.org/web/20020808224043/integra.cyberglobe.net/caraudio/resour ces/fiberfill/ |

I've used carpet padding with great success. Easily attached and secured with only staples. Cheap too. Stay away from fiberglass insulation. The fibers aren't safe when expelled from the box. |
