2.3.3 Removal/Reattachment of Acoustic absorbent pads
A

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. 1.

1 Remove this acoustic absorbent pad. When reattaching, roll it and push it in under the reinforcing plate. As only this acoustic absorbent pad must be fixed with adhesive, before pushing it in, apply adhesive to the side board of the cabinet. (Adhesive: DIABOND black/GYL-014)

2 Remove this acoustic absorbent pad When reattaching, place it along the surface inside the chamber so that it forms a U shape.
