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 awe-inspiring 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 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 tent,h 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 15-gauge 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 bac,k 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
