0444's in 76. thats the latest ive heard of that stamp. got any pics? but they still could be muellers, what do your ears tell you when you play through them?jape88 wrote:I've even got a quad of H30's from '76 with 0444 on the cone which according to Barron Greenback could be pulsonic!
I think the mistake people make is thinking the cone codes are specific to a certain manufacturer. Thats definitely not always the case. The cone stamps resembling 1777 and 444 are celestion part numbers in my opinion, not manufacturer signature stamps.
Im convinced Ive got 1777 and 0444 stamped pulsonic cones on some of my mid 70's speakers, and Im convinced my early H1777 cones from 65 and 66 are exactly the same as my early 102 003 cones from the same period. similarly the SP444's are the same as the 014's. different stamp, same cone. in the mid 70's weve got same stamps, different cones it seems.
These are speakers. Let your ears decide!
