LUR66EꢀINSTALLATION  
SoundꢀCoverageꢀandꢀSpeakerꢀPlacement  
The LUR66E is sold separately, as many outdoor installations have multiple zones. It is  
assumed for the purpose of this manual that the rock speaker will be installed using a  
minimum of two speakers. When deciding on the placement, allow for a total coverage  
area of approximately 100 to 450 sq.ft. per pair of rock speakers. This estimate is based  
on the ambient noise levels of a typical outside patio or yard and your personal listening  
level. If you are using your speakers in a high noise area where your sound coverage  
requirement is influenced by high automobile traffic noise or located in close proximity  
to a heavily industrialized urban area, or If you desire music over a physically large area,  
it is best to have a larger number of speakers playing at low volumes, rather than a few  
speakers playing at high volumes. Multiple pairs of speakers placed in strategic locations  
within your coverage area can be a fundamental solution when designing an outdoor  
system that requires large coverage.  
Ideally, you should place the speakers as close to the primary listening area and audio  
source as possible. The volume of the speaker decreases rapidly as it is moved further  
from the listener. Keep this in mind when planning the wire run to each speaker location.  
Patios, walls, and other features in your yard may be difficult to get around when wiring  
your speakers, so properly planning your design is important. Measure twice, dig once.  
The grilles are not designed or intended to be removed. Do not attempt to remove the  
grilles from your rock speaker. There are no user serviceable parts behind the grille and  
removal will damage the speaker.

LUR66EꢀCONNECTION  
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.  
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.

LUR66EꢀTROUBLESHOOTING  
Distortion  
If you hear obvious distortion from the speakers,  
immediately lower the volume level of your receiver.  
Distortion often indicates the speaker is being over driven,  
and damage can result by playing at high volume levels for  
prolonged periods of time.  
UsingꢀLoudness  
The Loudness function on most receivers is designed to  
enhance the bass and treble (for background music or  
listening at low volume levels).  
UnnaturalꢀSounds  
Distorted or unnatural sound can indicate poor connections,  
defective electronics, poorly recorded source material or  
speaker failure. If only one of your speakers has poor sound  
quality, check the speaker wire and audio connections.  
SwappingꢀSpeakerꢀ  
Locations  
That doesn’t fix the problem? Try putting each speaker in  
place of one another (swapping). If the sound remains poor  
on the suspect speaker after swapping location and the  
distortion moves with the speaker to the new location, the  
speaker may be the problem. If the distortion remains in  
the original location then the problem is elsewhere in your  
audio system or speaker wiring.
