Thank you guys. I heard good things about Mundorf but I am not sure if they are better than Alpha-Core. Yes, in terms of guage (10 AWG) they are better than Alpha which come in 12AWG. I decided to go for NorthCreek Music's 8 AWG custom inductors. They have not arrived yet. Will post the results after they are broken in and I have heard them enough to make concrete observations.
Rodman99999 (did I count the 9s right? :)), thanks for the suggestion but my apeaker (moded Apogee Fullrange combined with another Apogee MR/TW) and its crossover is my own creation and hence there is no reference value. It is a first order 6db crossover at 400 HZ. The impedance of the woofer is 1.9 ohm which makes the inductor to be around 0.8 mH.
