Quick Set-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.) For a larger "sweet spot" and multiple listeners, place tweeters on
the outside. Single listeners may choose to place the tweeters on the inside. If you
do, cant the speakers inward su
ffi
ciently so that the tweeter is not ahead of the
bass and midrange in time as shown in the diagrams below.
Whether the
tweeter is on the inside or outside, the tweeter should not be closer to the
listener than the bass section. Measuring from your seated position, if the
bass panel is 10 feet, 6 inches, the tweeter should be at least 10 feet, 7 inches
(think in distance, not angles).
Tweeter attenuation may be necessary for rooms with hard, re
fl
ective walls. See
Section 14 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-
fi
ts-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.
