Funny how one letter makes a huge difference. 808 8("b") can be converted to an 802 8g with a correct diaphragm change. The 808 8("a") can not. Different motor/magnet size.Originally Posted by VolvoHeretic

Actually motor and mag are the same- it's the Tangerine that's the difference. But a letter CAN make a lot of difference.
The 291-16 A is small Alnico motor large format can convert to 288C
16B is big Alnico motor, 16C is big Alnico and Tangerine, convert to 288g and H respectively

I was surprised to see "D-140" not realizing that later models used ribbed cones.
That said, it was as obvious to me that they were NOT 421's as it was that there's a 911 parked behind them.

Been a while since I did any, but the old Alnico JBL's used to freely take each others kits...ie D140 could be 2205, etc.

I suspect this is where polarity issues i've encountered in the past have come from. For example when a driver that observed the old convention where + signal applied to the black terminal moved the cone forward was re-coned with a newer kit made in accordance with the modern convention of + signal to the red terminal moves the cone forward.
Long story short, i learned to battery test every JBL when i acquired it.

Guess you understand old speakers forwards and backwards.
