Mike's Take

The 3.7 takes everything the 2.7 does and pushes it much farther. The 40-inch ribbon becomes 60.6 inches. That extra length gives the speaker more air and sparkle, more detail, and more effortless top end.

You also get additional surface area in the midrange and bass sections. The 3.7 has support structure behind the Mylar so that even though it is still a single sheet, the driver behaves as two separate radiators. This improves separation and reduces distortion.

One important detail: the 3.7, the 20.7, and the 30.7 all use the exact same true ribbon tweeter. That is why the 3.7 is such a strong value. You are getting the same tweeter assembly used in a $55,000 flagship.

Magnepan 3.7i Reviews

"I have so far found that the Magnepan 3.7i does an unusually good job of creating soundstages so precisely three-dimensional that they seem, at times, almost to wrap around the listener, so that some musical information appears to originate from the sides of the listener (and not just from the front of the listener).

-Chris Martens, the absolute sound

"The bottom line is the Magnepan 3.7i is a noticeable improvement over the 3.7 and a true value for the money..."

-Scott Robertson, Positive Feedback

"With its front end, MG-3.7i delivered music surprisingly effortlessly and harmonically correctly. So, Magneplanar lovers can certainly be relaxed with the new i-model. The traditional Maggie goodies still exist, naturally."

-Keijo Tanskanen, High End News
