Radian 1225-16 Diaphragm Fits Most JBL 1" 16 Ohm

I have successfully replaced around 1/2 dozen OEM JBL diagrams in JBL horn drivers. I sweep them at 500Hz to 1Khz while carefully tightening the mounting screws to insure the voice coil is not rubbing along with the rest of the replacement procedures. We had a pair of JBL 4430 studio monitors in the audio lab at RCA in Indianapolis. They sounded wonderful and I still consider that model my personal listening reference for all my audio work. The 4430's horn driver used a diaphragm that this item replaces. Anyway, I have a pair of the 4430 horn and drivers in current use in a larger room used for live performances. I have tried everything using all JBL OEM drivers, but I just could not get the rich smooth sound I remembered from the studio monitors. We lost another diaphragm recently due to microphone feedback. A vendor recommend I try this diaphragm as they are reportedly a bit more sturdy and smooth sounding than the OEM JBL. I was very reluctant to move to a different brand than JBL, but I just installed one of these. In my opinion, this diaphragm duplicates the rich and smooth studio monitor sound using the clean analog source material with the built in analog crossovers built into the 4430's. I am very pleased with the sound of these diaphragms. Snare drums have sharp and accurate attack and sound very real. Vocals are smooth and pleasing. I have not run pink noise on these yet compared to the OEM JBL diaphragms, but I will certainly log the difference in my notes for future reference. I recommend using this model compared to off brand replacements if one is looking to save money. Again, in my opinion, these sound better than the OEM JBL replacements. -hightechhick
