First, came the 3.7
The 3.7 is a 3-way design, like the 3.6, but, it is a full-range ribbon design, like the highly acclaimed 1.7. We are calling it “trickle-up” technology. The concepts that worked so well in the 1.7 were incorporated in the 3.7.
The 3.7 was subjected to “blind testing” by a panel of audiophiles and casual listeners. In addition to better sound, there is one more important improvement that you can test for yourself. If you have the opportunity to hear the 3.7s at your local dealer, try this experiment—Ask the dealer to place the speakers with the tweeters on the outside. Note how the imaging remains remarkably stable when seated far off-axis. With some speakers it is necessary to sit in the “sweet spot” for good imaging. With the tweeters on the outside, the 3.7 has the widest sweet spot of any of any previous Maggies. If you prefer to sit only in the “sweet spot”, try the tweeters on the inside (Be sure the speakers are toed-in).
The introduction of the 3.7 during CES 2011 was very similar to the introduction of the 1.7 during CES 2010. In their show coverage, www.theaudiobeat.com summed up the reaction of many who heard the 3.7 at the Audio Research and Magnepan rooms — “In terms of high-end audio in early 2011, we don’t know of a more important and impressive debut than that of the 3.7.”
Editorial on 3.7s and Magnepan’s CES demonstration begins in second column of link below. Gary Reber states —
“These are without question the best performance/value in loudspeakers that I have experienced. American-made throughout, these high-resolution, full-range ribbon, planar loudspeakers set a new benchmark for high-fidelity performance in loudspeaker design. No other demonstration at the CES came close to the sonic and spatial realism, and seamless response and time coherence delivered by the Magneplanars!”

Then, the 3.7 became the 3.7i
In past model improvements, driver changes and factory retooling were extensive. It is rare when improvements can be made that are audible in a blind test and do not require a major investment. So, in view of this good fortune, we chose to pass on these small improvements rather than save them for a 3.8.
Will you be able to hear the difference between the 3.7 and 3.7i? Yes, in a careful A-B test, but we don’t do sales hype. It is not a 3.8.
