CONNECTION
Connections
The LUR66E rock speaker has a two-conductor speaker wire surrounded by a cable
sleeve exiting the bottom of the speaker. Any speaker cable used to extend the
connection should be of a similar size (wire gauge) running from the speaker location to
your audio system.

You may wish to purchase certified direct burial cables (environmentally rated speaker
wire) and/or a watertight burial box which also works well for the purpose of protecting
your connection. Burial cable or wire rated for in ground installation is available at most
hardware stores and home improvements outlets.

The cable or wire can be run either directly beneath the speaker into the ground, or you
can use the notch on the bottom edge of the speaker enclosure to exit the cable out the
rear for hard surface installations. When attaching the cable to the speaker, it is critical
that a high quality connection be achieved. Poor connections will lead to corrosion,
possible loss of signal and/or a decline in audio performance.

When possible, try to reduce the distance of your speaker from the audio source to
achieve the best audio results. The optimum run should be no longer than 50' for the
most favorable results. Runs longer then 50' are possible, but may require larger gauge
wire. It is recommended to use 14 or 12 gauge for speaker wire runs longer then 50'.
Ask your Dual dealer or consult a professional contractor if you have questions regarding
long wire runs.

Parallel or series wiring is commonly acceptable for the LUR66E rock speaker to gain
correct amplifier loading. For best results, avoid series wiring The LUR66E speaker with
any other speaker type or brand.

The LUR66E speaker wires are marked for polarity for determining the positive and
negative identity of the individual wires within the molded pair insulation. Polarity is
shown by either a color or 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 on the speaker, and the
negative (-) terminal on the receiver to the negative (-) wire on the speaker.

negative (-) terminal on the receiver to the negative (-) wire on the speaker.
For a typical audio installation, all speakers in a system will be connected with the same
respective polarity. 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.
