I see what you are saying now Convergence- nut there is a bit of confusion.
What was marketed as the Mastering Lab crossover was for the 604.
Was that dual 411 monitor ever marketed? I don't believe it was.
I have seen numerous Mastering Lab crossovers for 604's- and have never seen one of those monitors.
The old Sound Practices site is long dead.

Hi
I looked at this drawing a few years back and concluded it was incomplete or inaccurate. When I contacted the author, CR, he just wanted to publish it for the "world". He wanted to know how it "sounds". I hope no one built this.
Check the LF coils 2 & 5.5 mH. The DCR would require # 24 or 26 AWG wire... not for a 604 or 605. Where are the LF caps ? Also my understanding is that Mastering Labs XOs were Time Aligned. This drawing is not.

Hi
Since I can not trust my memory at 1 AM , I recalculated the coils
2 mH and 1.3 Ohms = 21 AWG
5.5 mH and 1.3 Ohms = 18 AWG
