Before you buy, get a schematic of your speaker. Some speakers, especially ESL's, have a resistor in series with the input. Solution: make up you own speaker cables with that specified resistance, and remove the resistor in the speaker. If you have mono blocks as I do, the speaker cable can be just short pieces of nichrome wire replacing that (probably garbage) resistor. Win + win.

@jhnnrrs Well John, you’re not wholly wrong, I’ll give you that. Void the warrantee, true. The rest, not so much. You have heard of wire wound resistors, perhaps? That’s "hokey nichrome wire", or some variant thereof. Guess you’d better tell Mills about your discovery. Thank goodness someone is too smart to fall for such "pretty bogus advice." The best resistors, like Vishay VAR, consist primarily of a metal resistive component which is laser trimmed to provide a channel with the specified resistance. Any guesses as to which metal they use?

Sadly, John, Vishay VAR can dissipate a maximum of 0.4W of heat. A speaker resistor is often rated at 10 W or more. So Vishay VAR could only work in a large and expensive array, and then you would still need another conductor. As for obtaining the required resistance, try a multimeter? Always at least three figures of accuracy. That’s 0.1%. Most OEM resistors are 5% at best. Yes, they use nichrome wire in toasters, and in space heaters. And in aerospace. So what? And didn't you ever wonder how a resistor works - by dissipating electrical energy as heat? |
