You added a resistor permanently?!!! Isn't that a bit of a problem with power handling?

Hi,
yes permanently and no to power handling. The resistor was a small value to make a fine adjustment to the speaker Q. I cannot recall the value but I used a short length of resistance wire inserted into one side of the speaker cable. It may have been 0r1 to 0r3, that sort of order spread over about 120mm of cable length. So heat is not a problem nor is power reduction. Hi Fidelity is more important.
It is only fitted to the bass cable since I have only run bi-wired or bi-amplified for very many years. The treble and mid units were not corrected.
