Whats Poly-Fill and how will it affect my subwoofers sound?
You’re probably already very familiar with Dacron polyester fiber-fill, or Poly-Fill – there’s a high probability you slept on a pillow stuffed with this material last night! But you may not realize how Poly-Fill can help your bass. Stuffing your enclosure with the right amount of Poly-Fill can make your box behave like it’s larger than it really is. This comes in useful if the size of the box you’ve bought or built turns out to be slightly smaller than the recommended size of enclosure for your subwoofer. Depending on how much Poly-Fill you use, you can actually vary the ‘perceived’ box volume by as much as 30%. You can also ‘stuff it’ if you simply don’t have room in your vehicle for the size of box your subwoofer requires. Try adding Poly-Fill to any enclosure – it can clean up your bass by minimizing unwanted box resonances.
