Hi all..hopefully someone knowledgeable on this can help me..I’m attempting to go a little out of my “refoam only” technical skills on speakers. Recently I obtained a pair of C38..they sound great EXCEPT one of the 1217-1290 drivers is very noticeably lower in sound. I switched the N1200 crossovers to eliminate them as the “culprit”, so the issue is definitely in the driver itself. Would this be a diaphragm issue, and if so, would anyone be able to tell me which one to purchase? And also, is it a somewhat easy job to replace for a “willing to try” novice? I will include pics of the meter reading I got..and also, this driver is the 8 ohm version. Thanks in advance!
