Use an iron or laminate core inductor that is rated for the power you plan to use. It will work fine. Using an iron core is not a compromise...
If you want a ballpark number for cost to DIY, factor around 6-8 dollars a pound. You'll see why no manufacturer I know of would use an air core in this application.

Further down the Janzen page they have the 12ga copper foil. Still expensive though.

I think we have all used iron cores for the larger values at one time or another but there always seems to be someone who says it spells the end of the speaker world as we know it. I'm not sure you can tell the difference if it's 200Hz and below so I say go for it. Uh oh, watch the flamers burn me bad.

this 16 gauge laminate core has half the DCR of the 12ga foil inductor and cost 1/3 as much. The DCR of the inductor must be factored in to the design of the bass cabinet, as it increases woofer Qes.
