2.3.3 Removal/Reattachment of Acoustic absorbent pads
Note:
When reattaching the Network Assy for the midrange/tweeter, before reattaching the closure panel, be sure to remove the
acoustic absorbent pads located behind the chamber. (See Fig. 2-11.) If the closure panel pinches an acoustic absorbent
pad when it is secured, air leakage may occur, which may result in poor performance of this speaker system.
Removal/reattachment of acoustic absorbent pads is necessary before or after removal/reattachment of the Network Assy.
1. Acoustic absorbent pads around the input terminals 2. Acoustic absorbent pads inside the chamber for
the midrange/tweeter
3. Acoustic absorbent pads around the Network Assy
for the midrange/tweeter
