Recently, all three mid-panels on one of my RM30 Series IIs’ (CDWG, OXO, TRT) comparative output dropped ~5dB lower than the other. Driver output was measured with a Radio Shack meter placed 8” away from the driver, vertically centered. I bought them new back in 2011 and they’ve always performed beautifully up until now.
Before measurements were taken, I tried swapping crossovers, cables and speakers from side to side and the output deficit always followed the same speaker. Now extreme settings on the “MID” L-pads (weak side turned way up and the strong side way down) are required in order to “balance” the left and right outputs.
Has anyone had a similar experience and were you able to find a solution?
