WARNING:

This speaker weighs 3.8 kg (8.4 lbs). Do not mount it
on thin plywood or a wall with soft surface material. If
mounted, the screws may come out of the flimsy
surface and the speaker may fall. This damages the
speaker or causes personal injury.

Do not install the speaker to a wall with nails,
adhesives, or any other unstable hardware. Long-
term use and vibrations may cause it to fall.

To avoid accidents resulting from tripping over loose
speaker cable, fix it to the wall.

To mount the speaker on a wall by using
the attached mounting bracket

Fasten screws into a firm wall or wall support as shown
in the figure, and hang the holes of the mounting
bracket on the protruding screws.
* Make sure that the screws are securely caught by the

narrow parts of the holes.

 Using as 2ch stereo speakers

Better stereo images will be obtained when the speakers
are slightly angled in towards the listeners.

 Using as front speakers in a multi channel

system

Position the speakers on both sides of the TV. The
positioning of speakers is important, because it controls the
whole sound quality of a multi channel system. Set up the
speakers on the basis of your listening position by following
the owner’s manual supplied with your amplifier.

 

Using as presence or surround speakers

Mount the speakers on a wall or place the speakers on a
shelf. Determine the best position by following the owner’s
manual supplied with your amplifier.

Note:
This speaker features a magnetically shielded design,
but there is still a chance that placing it too close to a
TV set might impair picture color or create a buzzing
noise. Should this happen, move the speaker away from
the TV set.
