SpeakerTek re-foam kits use only top quality high density poly-ether foam surrounds in all of our kits. We sell no surplus or low grade surrounds of any kind. We warranty all of our kits and offer customer support by e-mail to help with any questions. This year marks our 38th year re-foaming woofers, and servicing loudspeakers.
Our special adhesives work with paper and all synthetic cones, such as polypropylene, graphite, Kevlar, aluminum, poly-mica, etc. These adhesives will ensure a solid bond at all of the critical points. This adhesive is specially packaged to ensure the proper viscosity. We recommend you use the adhesive within 30-60 days from the time you receive your kit.
Here are some recommended steps:
1. Check the quality of your woofer, and consider upgrading with a replacement woofer. This is always good to consider especially if your woofer has a small magnet, is cheaply made, or looks like it might be worn out.
2. Check your woofer to make sure it moves freely without serious scraping, or that it is not seized up tight.
3. Check your woofer with a low volume audio signal to make sure it is working o.k.
