Magneplanar 3.7i Instruction Manual
Quick Step-Up Instructions
The 3.7i has exceptional phase characteristics that are accomplished without
the use of compensation networks. To realize the optimum phasing, the 3.7i
should be angled inward as shown in the diagrams in the manual. (Do not
place parallel to the front wall.) The most precise imaging for a single listener
is with the tweeters on the inside. For a larger “sweet spot” and multiple
listeners, place tweeters on the outside. But, in both cases, the speakers must be
angled inward as shown in the diagrams below .
Your 3.7is have been shipped with the tweeters disconnected.
You must install a resistor or jumper for the operation of the tweeters. Most
listening rooms will have the smoothest response when using the enclosed 1
ohm resistors for the tweeter and midrange. Rooms that are large and/or
overly-damped may require the enclosed jumper for smooth response.
The 3.7i provides more options for getting the bass just right for your
particular room. There is no one-size-fits-all for every room. The 3.7i has
provisions to adjust the relative levels of the bass, midrange and tweeter. The
default position for most rooms requires attenuation of the midrange and
tweeter with resistors. If that does not achieve a smooth balance in your room,
additional bass diaphragm area can be added with one or more Maggie Bass
Panels.
