Magneplanar 1.7i Instruction Manual 

Quick Step-Up Instructions

Remove the steel magnetic strip from the front of the speakers. If the fabric 
sticks to the diaphragm, use a high tack tape to gently pull the fabric loose 
from the diaphragm. 

Th

e 1.7i has exceptional phase characteristics that are accomplished without 

the use of compensation networks. To realize the optimum phasing, the 1.7i 
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

ciently so that the 

tweeter is not ahead of the bass/midrange in time as shown in the diagrams 
below . 

Tweeter attenuation may be necessary for rooms with hard, re

fl

ective walls. See 

Section 14 below.
