Dual LUR652E, LUR65EW CONNECTIONS-POLARITY

Caution: Do not attempt to connect the speakers to any source, amplifier or receiver that

is turned on. Be sure the receiver is off prior to connecting the speakers.

Parallel or series wiring is commonly acceptable for the Dual ROCK speakers to gain

correct amplifier loading. Avoid series wiring your Dual speakers with any other speaker

type or brand.

In phase installations will take special care to connect the speaker wire runs in phase

using the correct polarity.

Polarity - Speaker wires are marked for polarity consistency so that you can determine

the positive and negative identity of the individual wires within the molded pair insulation.

Polarity is shown by either a color stripe on the insulation, by ridges molded into one side

of the insulation, the color of the insulation case around the wire, or by the color type or

colors of the wires/wire itself (copper or silver).

Important: In order to maintain correct polarity, always connect speaker wire using the

positive(+) terminal on the receiver to the positive (+) wire, and the negative (-) terminal

on the receiver to the negative (-) wire.

For a typical audio installation, all speakers in a system will be connected with the same

respective polarity. The speaker connections are located on the bottom of the Dual ROCK

speaker.

For best results, crimp or solder the wires together using heat shrink to seal each

individual conductor. After the individual conductors are sealed, seal over the pair with

another layer of heat shrink.

Connection Tip: You may also use twist nuts specially designed for outdoor applications.

These twist nuts have a silicone core inside the nut head and coat the connection once

attached. These special nuts are not included but are widely available.
