Thanks Anil and Viren for your inputs.
Unlike the past when I ddnt know about local options and bought my inductors from Madisound/Solen, this time I plan to get them wound locally, in a circular shape, using a plastic bobbin as the former. I had planned on 14 gauge AWG, since that is what the designer recommended, but will check on 18 gauge as well. Would the winder be able to predict dcr value before winding or is it possible only after it is wound? My values are 1, .50 and .25 mH, in pairs.
My son has the tweeters ordered, is on the lookout for mids-sometimes some amazing pre owned deals come up if you live in the US! Someone pointed to Usher drivers, saying that they are a good SS clone. Since the SS tweeters are already on the way, we decided to go for SS mids as well.
