• •IZO Home Goods Poly Fiber works great for stuffing small enclosures or transmission line cabinets.
• •Can Also be used craft or other home decor project and stuffing toys / pillows etc.
• •The sound wave coming off the back of your subwoofer reacts with the air contained in the box. Polyester fiber stuffing slows down sound waves inside the box, making the subwoofer perform as if the box were bigger. Use 1 to 1-1/2 pounds of stuffing per cubic foot of box volume
• •When Poyfill is added to your enclosure, the airspring within the box begins an isothermal process. When the air passes through the Polyfill it is scattered and dissipated by the fibers, causing the air to be less dense. The speaker then interacts with the enclosure as if it is larger than it really is, changing the sound.
• •Often times you'll either build or buy an enclosure for your equipment and it will be just a tad too small. In these cases you can easily add some Polyfill to the box to increase the effectiveness of your subwoofer. So do yourself a favor and research the proper amounts of Polyfill to add to your subwoofer enclosures to ensure you have the best stereo system out of all your friends.
