Magnepan 3.7's versus 20.1's?


Anybody here had the chance to compare the new Magnepan 3.7s with their longtime flagship 20.1 speakers?

15' is fine povided you place the tweeters inside. My 3.5s performed well in my listening room with about the same width. Currently, I have the 20.1 in the same room without any problems.
I have a 20X15X9' room. Back wall opens to entrance hall of house via 8 foot wide portal so room may be "bigger" in that sense.

MG20's work well I find.

I prefer tweeters on outside and have good central imaging with msuicians hanging in space (not attached to speakers). Depending on recording I can hear sounds lateral (ie "outside") the speakers.

Speakers generally "disappear".
Anyone can recommend an ideal sub for the 3.7 as I'm used to the Wilson Audio Puppy bass. Very low and dynamic and how do I connect it to my Goldmund Telos 3.9? Like the speaker but really need a sub to go down to 20hz.
