Eminent LFT-6 Installation Manual Download Page 1

A complete technical description of the LFT-6 is included in this
manual and begins on page 8.  It is recommended that you become
familiar with this information as a thorough understanding of the
LFT principals will assist you in the proper set up of these
loudspeakers.

Position the box on its side and open the end of the shipping carton.
Remove the padding from the bottom and slide the speaker from the box as
shown below.

Open

After removing the speaker from its carton it can be leaned against a wall
standing up or placed with the front face of the speaker  flat on the carpet.
Then the bubble wrap should be removed.  The wrap also holds the baffles
(black triangular boards) and the grill cloth (covered by a large cardboard
sheet) to the speaker.  After the wrap is removed these will separate from
the speaker.

Do not attempt to remove or loosen hardware on the drivers
themselves.  The magnents are held together under great force and
personal injury could result.
