Thanks for the link. It appears that the inductor change with length. I was told that the inductors were bury in some glue that minimize resonance so to modify the inductors for different length is essentially building a new network hence not cost effective.
Transparent network can't be reclibrated for different leghth?
Got a pair of reference bricks runs on in wall reference with 20'/23' length. Ask them to shorten that to 8' but they strongly recommend not to do so as the brick can't be re-calibrated to different length(in this case shorter). Was wondering if anyone tries to do the same and how did it actually end up affecting the sonic performance?
