Maggies with a subwoofer system - optimization?

**Littl** Ribbon Speaker in action, 
WOW *Little** yet HUGE on soundstage.
Highs off the charts.
WOW 
can 't wait to order a  pair.... And yeah I can hear th performance  of these speakers THROUGH my $10 comp speakers.

If they are anything even close to what I imagine I'm hearing,,,I'll be a  happy audiophile camper

Here I found the YT vid
My tech geek disses this DIYers ideas as *bunk*
I'm  with Hifi Guy
THis guy knows his stuff
I just have to figure out what electronic xover to add and how to add it, as my tech wo't have anything to do with it.
To me it makes alot of sense, cutting some of the lowest hz's off the Magnepan , thereby giving more voice to upper bass/mids and highs.
makes alot of sense.
Not sure how to go about it.

@tom8999 @millercarbon Tom, I have a pair of Magnepan 1.7i on my solid state system driven by a pair of Bryston 28B3 monoblocks. As for lengthening the life of your Maggies? I think that is overthinking things. As for the bass, if you are like me, you were in Maggie bass-denial for some time. You don’t know what is missing because you haven’t heard it. Let me cut to the chase. Maggies are incomplete speakers. They need to be considered as part of a “kit”. Unfortunately, not all the components of that are obtained from Magnepan. Here is what I recommend to be in the Maggie “kit”:  1. The Maggies of your choice. 2. The Mike Powell Ag upgrade jumper and tube (in lieu of fuse). 3.  A pair of MyeStands or similar for the Maggies. 4. A pair of REL T/9i or the new T/9x subs connected to your amp(s) with high level input cables, preferably good ones (Kimber or Analysis Plus). That is the “kit” IMO. Of course I recommend an amp or monoblocks with lots of power for dynamics, transients and headroom plus good speaker cables. Do all of that and you will be in LOVE with your Maggies! Done. 

Hi. I’m listening to Quad ESL63s using a Hsu sub to handle the load below 90 Hz. I’m listening thru a Marantz AV preprocessor, so I use the sub crossover settings in the preamp to handle the integration. It’s working great to my ears (and to others who hear my rig). Using the prepro allowed me to experiment with different crossover frequencies until I found one best for my room. 
Getting the low frequencies out of the Quads really freed them up. Maybe the same for Maggie’s?  YMMV…

This sounds like what the OP is looking for. Video based on LRS but the basics apply
