I'm building a 500Hz crossover & confused as to which inductors to use. I need a 2.4 & a 2.7 in this design.
Research so far says that they should be the lowest resistance for the best bass performance. I looked at the North Creek Audio, but their 12# resistance is 0.27 & 0.30. I'm looking at Solen 10 gauge which have a resistance of 0.17 & 0.18. I've also heard good reports about the copper foil coils, but notice that their resistance is considerably higher.
Any advice as to the best type for the best bass performance.
Thanks,
John

Lowest resistance is best, but if you look at the effect of a fraction of an ohm increase in resistance, it's going to be a fraction of a dB decrease in bass output, and a slight decrease in the amplifier's damping factor as seen by the woofer. One would need the schematic of the crossover and the impedance of the drivers to be able to calculate the exact difference. This can be easily done with a spice circuit simulator.
"Good enough" may be close enough to "best" that it doesn't matter, in which case you can use higher resistance, lower cost inductors with no noticeable loss in bass performance.
