The 3.7i

The 3.7i is the first model in our floor-standing lineup to incorporate our famous ribbon tweeter along with quasi-ribbon bass and midrange drivers. 

As Jonathan Valin says "Maggie's three-way, true-ribbon /quasi-ribbon planar 3.7i successfully addresses three issues that have long plagued "true-ribbon" Maggies: the seamless integration of that ribbon; the retention of detail and dynamic range at relatively low volume levels; and the reduction of "Maggie grain."  The solution of these problems combined with the famous virtues of true-ribbon Magnepans produces what is, in JV's opinion, a best buy....."

Now available with the X Upgrade! 

The general idea of the ‘X’ program is to take the existing design of a given speaker, and simply, almost one-for-one, replace all of the components leading up to the driver, with superior ones. This yields a noticeable, graphable, and awing improvement. There are certain model-specific features, but the MG___X Upgrade Program is at its core characterized by the following factors:

• Better Capacitors - All capacitors that aren’t already, are replaced with high quality, copper-rich, polypropylene capacitors [banks]. Each capacitor [and bank] used is individually tested to the hundredth such that left and right crossovers’ capacitances are within five thousandths. With the increased level of testing and decrease in tolerance, minor value tweaks are employed in some models resulting in fewer capacitors used and a smoother response overall.
• Better Coils (Inductors) - All coils that aren’t already, are replaced with high-gauge, copper wire, air-core, bobbin wound coils [arrays]. Each coil [array] used is individually tested to the tenth such that left and right crossovers’ inductances are within five hundredths
• Better Wiring - All wiring (aside from the green (+) and yellow (-) wires for True Ribbon Tweeters) is replaced with 15ga or higher solid copper wire. Excess wire (for ease of assembly, for instance) is completely removed. C
• Better Connections - All connections within the circuit, from the solder lug attached to the terminal screw on the nameplate, to the crossover board, to the driver terminal block, and back are soldered connections. Besides the terminal screw,
  solder lug, and jam nut connection on the nameplate, there are no mechanical connections used
• Better Inputs - All nameplate components are gold rather than nickel
