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. 2-11.) 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.
