Which Magnepans for my small room?

Did you audition with subs?  You have two and that would make a huge difference.  Elizabeth can suggest how to calm the brightness with resistors.  She has put some time, money and effort into this.   Too bad you could not compare with the larger models.

@smodtactical, if at all possible, try and give a listen to the Eminent Technology LFT-8b. It contains a pair of magnetic-planar drivers (in some ways similar to the 1.7, different in others) for frequencies 180Hz to 10kHz, a ribbon tweeter for 10k up, and an 8" sealed woofer for 180Hz down. You might find it more to your liking that the 1.7i. Pro reviews available on the ET website.

I just cannot imagine a pair of 20.7 in my room.....
After finding a $450 pair of MMGi kicked sand in the face of my old Joseph Audio RM33se " boxes" I have been quite content.
With just one ML Dynamo sub I have all the bass I will ever need. And it is so dialed in even staring right at the sub you cannot tell that is where the bass is emanating from.
Bright? Sibilant?
Not in the slightest.
Effortless dynamics and grace.
Vocals and acoustic instruments are sublime.
Running tweeters out.
4 ft from back wall
4 ft from side walls
10 ft apart slightly toed in
The largest sweet spot of any speakers in my room ever.
I just cannot imagine how much better going up the range might get but......
As of now zero interest. 

@uberwaltz what other speakers have you compared the MMGi too? Helps me understand your praise better. Thanks!

Smod.

Just as a fyi, I have an absolutely terrible listening room acoustically being literally 4 walls of glass and a tiled floor and sloping ceiling.
I have found most " box" speakers just do not work in here so you have to bear that in mind.

But here goes.

B&W 803
Wilson witts
Focal 1026
Devore Gibbon
Joseph Audio RM33se.

And a lot more I cannot put names to right now.

Out of them all the Gibbons were the best.

However the Maggie's are just in another dimension for myself.

Now again, this is in my room, with my gear and my ears.
Room is approx 18x12 with sloping ceiling from speaker end back to me of about 11ft down to 7.5ft.
The layout of room precludes any speakers getting anywhere near the corners which likely hurt all the boxes but is perfect for the Maggie's.

Oh btw I like them just a bit.......
