This is the closest I can replicate my Lo1166A ( beter sounding one).
I have 2 originals, and they are so different, This one is so hard to match because of high-frequency roll-off. Another one is easy to replicate, very similar to Carnhills.
I match DRC, interwinding capacitance, wire capacitance, q factor, inductance, and leakage inductance, frequency response. Bass is matched to 0,03 dB and 20 hz 0,05 db difference...but still, I'm not 100% happy.
I'm noticing so small a difference in deepest frequencies. Mids and high are great, can't hear the difference, but, Although can't see it on the graph, a small difference exists.
I will find a way to equalise that.
I will experiment with laminations, so hard to find.
Any ideas?
