There are 2 xovers from the factory.
Internal is midrange to tweeters.
External is mid to bass.
Unless surgery has been done by a PO, the active xover simply replaced the Magnepan external unit. Did you receive any xover boxes?
The Marchand XM26 came with this pair (they came with Mye stands, too), but the factory external crossover did not come with them. So are you saying that the factory external crossover was a requirement, rather than an upgrade option?
Grants 100% correct, I have the MG20's but they did not come with the factory XO so I had Phil build one for me (XM44 two-way). Took a while but I was overseas so it didn't matter. Cost me $1500 in 2010 but they're around $2K now I see.
He threw in a bunch of different modules (cards) to play around with but I haven't gotten around to them.
As Tim said, you need one or the other.
One stereo amp and the Magnepan passive xover, or 4 channels (a 4 channel amp or 2 stereo amps) with (usually) an electronic xover ahead of the amps.
There are other options, including making your own passive mid-bass xover.
Honestly, bi-amping is a great improvement if you can swing another amp. If not identical as existing, you'll have to horizontally bi-amp.
Nice on the Mye Sound stands inclusion. ;)
Okay, great to know this! I missed Tim's informative post (operator error on my part, new to the site), but now I've read it and see the schematic he attached also. I do have the XM26 horizontally bi-amped with non-identical amps. Thank you both for the info!
Here is the 20.0 XO posted on the MUG. The part in the dotted line is the mandatory external XO which prevents low frequencies from going to the mids and tweets.
You need either the Marchand XM26 (or equivalent) or the passive XO to protect the mids and tweets/ribbons from the bass and sub frequencies.
The external xover would look something like this.
