Which inductors??

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
