Hello everyone,

while surfing through the offers of a well known German musical instrument supplier I've found a genuine JBL D8R2425 diaphragm as well as a Radian 1225-8. They call € 189 for the JBL and € 99 for the Radian. Should I ever encounter the need of new daphragms in my 2421A's, would they fit? At a visual inspection the look very similar to the 2421's at least. And what's the difference between the JBL and the Radian diaphragms? Can the Radians compete with the JBL's that almost cost double the money?

Best regards!
