Note: Your 151 ® SE speakers can be mounted vertically. However, when mounted vertically you

Speaker cord consists of two insulated wires. The wire marked with a stripe or rib is used
for the positive (+) red terminal connection. The plain wire is used for the negative (–) black
terminal connection. Strip approximately ½ inch (1.3 cm) of insulation from the ends of both
wires (Figure 6). Then, twist the ends of each wire so there are no loose strands.
CAUTION: Before making any connections, turn off your receiver/amplifier and unplug it from
the AC power outlet.
1. At the back of your speaker (Figure 6), unscrew the hex knobs on the terminal posts until
you can see the small hole going through each post.
2. Insert the marked (+) wire into the red (+) terminal. Insert the plain (–) wire into the black
(–) terminal. Tighten the knobs to secure the wires.
3. Check the speaker connections carefully. Make sure no loose strands of wire touch
across terminals creating a short circuit that can damage an amplifier or receiver.
Note: After making the connections, any bare lengths of speaker wire can be affected by expo-
sure to the outdoor environment. To protect the speaker wires, apply a thin coating of silicone
caulking material, such as RTV adhesive, to any bare sections of speaker wire.
