    Looking for 8" surrounds for Jamo 20383 (707) woofers.

    Does anyone know who sells surround kits for Jamo 20383 found in model 707??. If I'm not mistaken, these drivers were made by Peerless in Denmark. Has anyone re-foamed these drivers? and what did you use. I sent Rick Cobb an email to see if he has something compatible with the same compliance.
