|After a 12 year run, the venerable 3.6 steps aside for the new 3.7The first question on everyone's mind-- "How is the 3.7 different?"
It is easier to start with what is the same. The frame and cosmetics are the same, with one important difference---the additional option of aluminum trim.
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 specifications of the 3.7 are nearly the same as the 3.6, with a minor increase in efficiency.
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."
3.7 becomes 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. And for those that have a 3.7, we have some good news.
For the first time in our history, we are able to upgrade your 3.7s at the factory for a modest $500. (That is what you have come to expect from Magnepan---good value.)
