I have a very similar setup on my 20's.
I went with the Marchand's tubed version with stepped attenuators, becayse it was only a little more.
The nice thing about the Marchand crossovers is that they are modular. If you later decide to have it made into a 3 way, the parts inside get reused.
That way, you can cut 50Hz down out of the maggies, and send it to a subwoofer or 2.
I found that with the crossover in the system the 20's sound better with the speaker wires to both tweeters reversed so they are out of phase with the bass panels.
