2.3.3 Removal/Reattachment of Acoustic absorbent pads

Removal/reattachment of acoustic absorbent pads is necessary before or after removal/reattachment of the Network Assy.

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. 2-8.) 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.

for the midrange/tweeter

2 Remove this acoustic absorbent pad. When reattaching,

roll the acoustic absorbent pad and push it in deep behind

the chamber. As this acoustic absorbent pad must be fixed

with adhesive, before pushing it in, apply adhesive to the

deep behind the chamber.
