Removing the front cover

The front cover, which is attached to the speaker
at six points, can be removed if desired. To
remove a cover, using both hands, gently pull the
top of the cover away from the speaker. When the
cover comes away, gently pull the bottom of the
cover away from the speaker. To reattach the
cover, line up the six pegs on the cover with the
six holes on the speaker, and gently push the cover
onto the speaker.
Note:
When removing the cover, be careful that you don't
touch the drive units, and don't exert excessive force
with any tools.
