Amazing pair of some of early Celestion ceramics . With the “new”heavy 25 watt ceramic mag and h1777 cones with dual doping. April 1966 dated I believe,pretty early stuff . These have the original paper voice coils the used for the first ceramics  . Doping on both sides 100% original. No rub, loose spider or issues(getting really hard to find. A little dirty but again strong sounding with no issues. Get them while you can and get your early Hendrix,cream on. Nothing else like these. Excellent sounding with again no issues. Original dual doping on both sides h1777 cone codes. Amazing these are solid like they are.
