■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.
WARNING
• This speaker weighs 5.5 kg (12 lbs. 2 oz.). 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.
Before making connections, make sure that
the amplifier is switched off.
Connections
• Connect the screw-type input terminals at the rear of the
speaker to the speaker output terminals of the amplifier
(or receiver) with the speaker cable.
• Connect the (+) terminals on the amplifier (or receiver)
and the speaker using one side of the cable. Connect the
(–) terminals on both components using the other side of
the cable.
• Connect the speaker to the center terminals of the
amplifier (or receiver) making sure not to reverse the
polarity (+, –). If the speaker is connected with reversed
polarity, the sound will be unnatural and lack bass.
■How to Connect:
1 Remove the insulation coating at the extremity of each
speaker cable by twisting the coating off.
2 Loosen the terminal knob.
3 Insert the bare wire.
4 Tighten the knob and secure the cable. Test the
firmness of the connection by pulling lightly on the
cable at the terminal.
Note
Do not let the bare speaker wires touch each other to avoid
damaging the speaker or the amplifier, or both of them.
[Using a Banana Plug]
1 Remove the speaker terminal cover by gently pulling it
toward you.
2 Tighten the terminal knob.
3 Simply insert the banana plug into the terminal.
