If it's anything like my KEF Reference speakers (and it should be) , it is not JUST a 10W resistor. It is likely to be of a specifically selected value from within the normal tolerance band, to enable the speaker to comply to it's specifications. KEF tested and matched up Rs Cs and drivers into bins to make sets that gave the correct crossover frequencies and attenuations. I'd be inclined to test the actual value of it's buddy in the adjacent speaker, and match the resistance to within 1% or so. Which contradicts your premise since the drivers are different and the resistors would have to be matched to THAT driver IF you think it's THAT critical. The only way would be to properly test it, which is obviously beyond the OP. MrT. |

Why not do it right, or get somebody competent to do it ? geoff |

Given the natural acoustic variations in the room, this level of matching while laudible, probably has very little practical value. |

Perhaps, but you do realise that does not require the resistors to be matched to 1% in any case? Not to mention the resistors may be selected to provide the matching rather than the drivers, thus making your idea pointless. Why not do it right, or get somebody competent to do it ? As I have said all along! MrT. |
