Got old Advent Prodigy speakers with foam surrounds that have rotted away? This refoam kit has everything you need to bring those 8\ woofers back to life. It includes new foam surrounds, shims to center the voice coil properly, and replacement dust caps. From MW Audio and made specifically for Advent speakers. If your speakers sound weak or the woofers look damaged around the edges, the foam has probably deteriorated - super common with older speakers. This repair isn't too hard if you're patient and careful. The shims help you align everything perfectly so you don't get voice coil rub. Really brings the bass back to your vintage speakers without having to replace the whole woofer. Much cheaper than buying new speakers or replacement woofers. Perfect for DIY audio enthusiasts who want to restore their classic Advents. The kit has everything you need except the adhesive (usually white glue works). Once done, your speakers will sound like new again. Great project for a weekend if you enjoy fixing things. Really satisfying to hear music coming through speakers you brought back from the dead!
