14. Rigging Precautions: When mounting or suspending EAW Commercial loudspeaker  
enclosures, it is essential that load ratings, rigging techniques, and special safety  
considerations be appropriate for the installation. Use only the mounting/rigging points  
on the loudspeaker enclosure intended for this purpose. The user must determine the load  
requirements, dynamic loading, and any other contributing factors affecting the loudspeaker  
installation. The user must determine the proper design factor for specific applications and  
the required load rating of the connection to structure. Comply with all applicable federal,  
state, and local regulations.  
EAW Commercial strongly recommends the following rigging system practices:  
Documentation: Thoroughly document the mounting/rigging design with detailed  
drawings and parts lists.  
Analysis: Have a licensed structural engineer or other qualified professional review and  
approve the mounting/rigging design before its implementation.  
Installation: Use personnel experienced and qualified for mounting/rigging loudspeakers  
in accordance with and in compliance with all federal, state and local regulations.  
DANGER: Loudspeakers should be mounted or suspended only by persons with knowledge  
of the proper hardware and rigging techniques. When stacking or pole-mounting  
loudspeakers, be sure that they are stabilized and secured from falling over or being  
accidentally pushed over. Failure to follow these precautions may result in damage to the  
equipment, personal injury, or death.

2. INTRODUCTION  
Congratulations on the purchase of your new EAW Commercial loudspeaker. You now  
own one of the finest professional audio products available – the result of exceptional  
engineering and meticulous craftsmanship. Please read these instructions to get the  
maximum performance from your new loudspeaker.  
Each EAW Commercial loudspeaker is intended for professional use. The construction,  
components, and hardware have been designed to provide robust, reliable performance for  
its intended application. Please ensure that you fully understand its proper installation and  
operation before use.  
This manual describes the VRS12 and VRS18 passive subwoofers. They are ideal for  
applications where maximum low-frequency impact is required. Both subwoofers provide  
high output, authoritative bass response for the lowest musical octaves.  
The VRS12 is especially suited for installations where space is restricted. It is 15.5  
inches/394 mm high when mounted on its side, and is very effective where subwoofers must  
be installed under a low stage.  
The VRS12 and VRS18 enclosures are the same height as the VR21 and VR51 full-range  
loudspeakers. Because of this, attractive arrays can be created with a single VRS12 or VRS18  
between two VR21s or two VR51s.  
The rugged enclosure is available in both black and white finishes. It includes a number  
of threaded points for use with forged shoulder eyebolts. The powder-coated steel grille is  
foam-backed, providing physical protection for the drivers as well as hiding them from view.

3. INSTALLATION  
Unpacking and Inspection  
Visually inspect the outside of the shipping carton and check for any shipping damage.  
After unpacking, if you find concealed damage to the loudspeaker, save the packing materials  
for the carrier’s inspection, notify the carrier immediately, and file a shipping damage claim.  
Although EAW Commercial will help in any way possible, it is always the responsibility of  
the receiving party to file any shipping damage claim. The carrier will help prepare and file  
this claim.  
Mounting Precautions  
The loudspeaker is fitted with threaded mounting  
holes, suitable for attaching user-supplied forged shoulder  
eyebolts and flying hardware. The details of the mounting  
points are shown in the drawings on page 10.  
WARNING: Installation should only be done by  
an experienced technician. Improper installation  
may result in damage to the equipment, injury or  
death. Make sure that the loudspeaker is installed  
in a stable and secure way in order to avoid any  
conditions that may be dangerous for persons or structures:  
Check to make sure that the support surface (e.g., wall, etc.) has the necessary  
mechanical characteristics to support the weight of the loudspeaker without the  
danger of it falling.  
Always use support elements suitable for the material of the wall that will support  
the loudspeaker (e.g., screw anchors for bricks, screw anchors for cement, etc.).  
Consult a building professional for the proper mounting hardware.  
Before suspending the loudspeaker, carefully check all the components to be used to  
make sure there is no damage, deformation, corrosion and/or missing or damaged  
parts that could reduce the safety of the installation.  
Consult a professional rigger or structural engineer prior to suspending loudspeakers  
from a structure not intended for that use. Always know the working load limit of the  
structure supporting the loudspeaker. Always make sure that the rigging hardware  
minimum rating is at least five times the actual load.  
Avoid installing the loudspeaker in places exposed to harsh weather conditions.

4. CONNECTIONS  
WARNING: To prevent the risk of electric shock, do not connect the loudspeaker  
with the amplifier switched on. The protective cover over the terminal strip is a safety  
feature per CE requirements. Replace this cover after making the signal connections.  
1. Remove the insulating cover from the loudspeaker input  
terminal strip.  
2. The positive (+) input terminal of the loudspeaker connects  
to the positive (+) output of your power amplifier.

4. Using a small phillips screwdriver, secure the connections.  
CAUTION:  
SUSPENDING THIS SYSTEM SHOULD BE DONE BY QUALIFIED  
TECHNICIANS FOLLOWING APPROPRIATE SAFETY STANDARDS  
5. Replace the insulating cover over the loudspeaker input  
terminal strip.  
Loudspeaker Cables  
Use loudspeaker cables with a minimum  
conductor size for the length you need as  
listed in these tables. This will minimize  
power losses to less than 0.5 dB. The  
cable lengths listed are “up to” lengths.  
For in-between lengths, use the next larger  
conductor gauge. Using larger than the  
recommended conductor size is always  
permissible. Using smaller than recommended  
conductor size will result in higher power  
losses.

times the nominal conductor diameter in millimeters.  
For cable lengths over 200 feet / 60 m at 8 ohms, and over 100 feet / 30 m at 4 ohms,  
the conductor sizes needed for less than 0.5 dB power losses are rarely practical  
for physical and cost reasons. As a practical compromise for these situations the  
recommended conductor gauge is 10 AWG or 25 metric.

Precautions  
To prevent inductive phenomena causing humming or distortion, the speaker cables  
should not be run together with electrical energy conductors, microphone cables, or  
line-level audio lines.  
Use speaker cables that have markings to distinguish the polarity, such as insulation  
or conductors of different colors.  
Before using the loudspeaker, carefully check that all the connections have been  
made correctly to make sure there are no accidental short circuits that could cause  
electrical sparks.  
Verify that the polarity of the connections to all of your loudspeakers is correct. When  
more than one loudspeaker reproduces the same frequencies, but with opposite  
polarity, there will be sound cancellations. Therefore, if any of the loudspeakers  
are wired so that the +/- connection polarity is reversed with respect to the others,  
incorrect reproduction will result. Most notably, the bass response will suffer. This  
is especially true when loudspeakers are situated in adjacent positions where the  
sound waves readily interact with each other.  
VRS12 and VRS18 – 7  
 
5. OPERATION  
Signal Processing  
The loudspeakers have no internal crossover, allowing maximum power transfer to the  
woofers. External signal processing is required to shape the line-level signals before they  
reach your power amplifier. The recommended high-pass, low-pass, and EQ setting are  
shown in the specifications table on the next page.  
Choosing a Power Amplifier  
There is no exact answer to the question of what amplifier size you should use for a  
loudspeaker. The loudspeaker power rating in EAW Commercial’s specifications only means  
it has passed a standard power test. This provides a rating that can be used as a point of  
comparison with other loudspeakers. This rating does not necessarily correspond to the best  
amplifier size to use nor is it a measure of a “safe” amplifier size to use. Rather, the amplifier  
should be sized according to both the sound levels required and the type of audio signals  
that will be reproduced. If you are unsure of how to determine this, consult with a qualified  
professional or contact EAW Commercial Technical Support.  
Preventing damage to the loudspeaker is a function of operating your audio system so  
that the loudspeaker is not stressed beyond its design limits.  
Operating Tips  
Do NOT drive any of your electronic equipment into clipping, particularly the power  
amplifiers. This can easily damage the loudspeaker.  
If driven into clipping, even an amplifier with a power output rating lower than the  
loudspeaker’s power rating can cause damage to a loudspeaker.  
Avoid sustained microphone feedback. This can quickly cause failure of high-  
frequency drivers in your system.  
Avoid extreme boosts on equalizers as these can cause excessive input to the drivers  
at the boosted frequencies. Generally, cutting frequencies is preferred to adjust the  
frequency response.  
With appropriate signal processing, your loudspeaker should produce exceptionally  
good sound. If it is used in a room with problematic acoustics, there is little you can  
do to overcome the room problems with electronic adjustments. Your best solution  
is careful placement and aiming of the loudspeaker so most of the sound is directed  
only at the audience.  
Most EAW Commercial loudspeakers are capable of sound levels that can be  
damaging to human hearing. Take precautions so that audiences are not exposed  
to such levels. If you must expose yourself to these kinds of volume levels, wear  
adequate hearing protection.  
Take care when moving or lifting the loudspeaker. Injury to you or damage to the  
loudspeaker can result from careless handling.

7. TROUBLESHOOTING  
Loudspeaker difficulties usually fall into one of the following categories. The causes for  
each are listed in the most likely order of probability.  
No Sound or Low Output  
Loudspeaker cables or connectors are not wired correctly or are faulty. Check  
all cabling, referring to these instructions for the correct connections. The best  
way to check a suspect cable is to swap it with a known good cable. Check the  
loudspeaker’s input panel to verify correct cable connections.  
Electronic equipment is not turned on, or the level controls are not adjusted properly.  
Make sure that all equipment in the signal path is powered up, and that all controls  
are set to appropriate levels for normal operation.  
Loudspeaker is not working. Connect the loudspeaker cable to a known good  
loudspeaker, leaving all equipment set to the same levels. If the problem disappears,  
the loudspeaker is probably not working. Contact EAW Commercial Technical Support  
for appropriate troubleshooting.  
Distorted Sound  
The power amplifier is clipping. The signal level is exceeding the limits of your  
system and you must reduce the level.  
Other electronic equipment is being overdriven. Ensure that no equipment in the  
signal chain is being over driven. For example: input(s) or summing bus in the mixing  
console, equalizers etc.  
Driver(s) not working properly. Contact EAW Commercial Technical Support for  
appropriate troubleshooting.  
Partial Sound (frequency band missing)  
Incorrect EQ settings in the electronic equipment. Ensure that all EQ settings and  
filters on the mixing console, preamplifier, or other equipment are set for normal  
operation. Ensure that level controls on electronic crossovers and associated  
amplifiers are correctly set, and that all cables and connections for such equipment  
are connected and working properly.  
Driver not working properly. Contact EAW Commercial Technical Support for  
appropriate troubleshooting.

8. SERVICE and MAINTENANCE  
Maintenance  
Usually, your EAW Commercial loudspeaker will not require regular maintenance for  
normal use. However, you can do several things to keep your loudspeaker in good operating  
and cosmetic condition.  
Testing: Periodically test your loudspeaker for proper performance. A simple test is  
to play a CD through it using well-defined, articulate, wide-range program material.  
Listen to ensure all drivers are working properly and for any evidence of distortion or  
other extraneous sounds. Test at several volume levels: very low, normal, and high.  
Mounting/Rigging: Any mounting or rigging hardware should be regularly inspected  
for security, wear, deformation, corrosion, and any other circumstances that may  
affect the load-handling capability. Immediately remove from service and replace any  
hardware whose load-handling capability may be compromised.  
Cleaning: Cleaning the exterior of the enclosure will depend on the type of “dirt.”  
Dust, food spills, or similar contaminants can usually be removed with a cloth  
dampened with water, or a mild household cleaner. Avoid using any strong solvents  
as this may damage the finish. Turn the amplifiers off before cleaning.  
Scratches or Dents in Wood Enclosures: Minor scratches on the enclosure can be  
painted over with an outdoor latex paint, or simply a colored in with a “Sharpie” or  
artist’s marking pen. More serious gouges or dents should be sanded out, filled with  
wood putty, and repainted. Touch-up paint in pints and quarts is available through  
EAW Commercial Technical Support.
