Introduction

ETON expressly thanks you for deciding to purchase this system and congratulates you on the selection of this excellent product.
The ETON loudspeakers are a guarantee for outstanding performance. The electrical, mechanical, and tonal characteristics will be maintained at the original high standard throughout the entire operational life of this product. We wish you many pleasant listening hours. The current operational instructions are designed to ensure the correct installation of the loudspeakers. They contain information and essential procedures for the correct operation of the product and its attached external devices. Please carefully study the operating instructions before beginning with the installation location or the connection of the loudspeakers.

Safety instructions

Attention
Please read all warnings found in this manual. This information is highlighted and included to inform you of the potential danger of personal injury or damage to property.
Hearing Damage
CONTINUOUS EXPOSURE TO SOUND PRESSURE LEVELS OVER 85 dB MAY CAUSE PERMANENT HEARING LOSS. HIGH POWERED AUTO-SOUND SYSTEMS MAY PRODUCE SOUND PRESSURE LE- VELS OVER 130 dB. THIS MAY CAUSE DAMAGE TO HEARING. USE COMMON SEN-SE AND AVOID SUCH RISKS!
Volume and Driver Awareness
The use of sound components can impair your ability to hear necessary traffic sounds and may constitute a hazard while driving your automobile.
ETON accepts no liability for hearing loss, bodily injury, or property damage as a result of the use or misuse of this product.

Mounting

Do not use your automobile until all components of the loudspeaker system have been secured to the interior framework. Failure to do so may turn a component into a dangerous, flying projectile during a sudden stop or accident. Do not drill or drive screws through any vehicle interior or carpeted floor before inspecting the underside for potential punctures to control lines or cables. Be sure to avoid all fuel lines, brake lines, electrical cables, or oil lines when planning the installation. We recommend disconnecting the battery. Please ask your car dealer if disconnecting the battery is possible without any problem.
Choosing a location
For simple installation use the original factory speaker location. Using these positions will save considerable installation time and provide the best optical integration. Avoid installing speakers behind thick stock fabric or cloth. This could – especially in the case of tweeters – restrict output and reduce the sound volume. Too near installation close to reflective surfaces can negatively affect stereo imaging. The distance between each mid/woofer and tweeter pair should not exceed 60 cm. We suggest first mounting the mid/woofer and attaching cables. Then you can determine the optimum tweeter location by auditioning the tweeters at several positions in your automobile before permanent installation.
Installation of mid/woofer
It is not possible to install the loudspeaker in the original factory speaker location, the most used position is in the door panel. After choosing a location, carefully remove the trim panels. Be sure that sufficient mounting depth is available and that no moveable, mechanical parts (window, window regulator handle) are restricted in their functionality.
Caution: Use care when removing interior trim panels. Car manufacturers use a variety of fastening devices that can be damaged in the disassembly process.
Use, if necessary, a drilling template (not included) to cut a suitable hole in the trim panel and, if necessary, in the sheet metal behind. Drill holes for the fastening screws. Mount the parts as shown in
ATTENTION
If sheet metal must be cut or removed contact your authorized car dealer for professional advice. By damage to supporting body structures, the safety certificate may be withdrawn. ETON-POW-20+-2-Wege-System-Loudspeaker-

If you plan to use grilles or panels in front of the loudspeaker, ensure that sufficient space is available for the path of the loudspeaker cone. Should the distance not be sufficient, the cone could vibrate against the grille or panel thus damaging the loudspeaker. Installing the tweeters can be flush- and surface mounted. Consider that repeated opening and closing of the car door can result in the loosening of the tweeter fastening devices when the loudspeaker is mounted in the door panel. Flush mounting: Use, if necessary, a drilling template (not included) to cut a suitable hole. Lay the leading connector cable and mount the parts as shown in
Caution: Use care when removing interior trim panels. Car manufacturers use a variety of fastening devices that can be damaged in the disassembly process.

The specialty of the ETON mounting cabinet is that the tweeter element can be turned and swiveled to achieve the optimum hearing path to your sitting position. See
Disassembly: To remove the tweeter element from the mounting cabinet, turn the element to its middle position and place two round metal rods with Ø1,0 mm to the limit in both openings right and left of the tweeter element. By swiveling the tweeter you can now move it upwards and remove it.
Assembly: Drill two holes for the fixing screws and one hole for the connecting cable with the aid of the surface-mounted housing. Note the desired inclination of the surface-mounted housing. Assemble the parts as shown in ETON-POW-20+-2-Wege-System-Loudspeaker-fig-2

Connection

Whenever you run wires through sheet metal, use tape or grommets to properly insulate the metal edges from cable jackets. This technique prevents chafing and possible short circuits that could damage an amplifier or the loudspeakers. Follow the wiring diagrams in figures 5 and 6 to connect the loudspeaker system to your automobile radio and possibly to an amplifier. Tweeters may only be connected via a crossover. If you want to drive the POW+ system fully active, an active frequency separation for the tweeters is still necessary. To do this, set the necessary values in your DSP or on your amplifier/source. A recommended crossover frequency for tweeters as well as for the bass-midrange drivers can be found on the last page (Technical Data).
Caution: Do not apply power to the tweeters without installing crossovers first! Replace the automobile battery connector and test the loudspeaker system. ETON-POW-20+-2-Wege-System-Loudspeaker-fig-4

IMPORTANT

Correct high-frequency polarity in the vehicle The correct polarity of the tweeter to woofer is a decisive factor for the sound quality of the entire sound system. A false polarity can even “destroy” the sound of the best loudspeaker system. In some cases, a polarity reversal (exchanged positive and negative poles) of both tweeters can result in sound quality improvement. This can result from the mounting position, the distance between Loudspeaker and listener, or also from the sound reflections in the vehicle. Since this is very specific, it cannot be decided until the loudspeakers have been mounted in the vehicle.
Evaluation of the correct high-frequency polarity
After the loudspeakers have been mounted in the vehicle, they are connected with the included crossovers. At first, the crossover should be placed in an easily accessible position, preferably directly reachable from the driver’s seat. To recognize the correct polarity as a rule the operation of one channel (either left or right) is sufficient. The correct polarity of the tweeter can be value-ted most simply from the volume. Adjust the volume control so that the music can be clearly heard in its full band (high, mid, and deep range). Play a segment of music (about 20-30 seconds) and pay close attention to the reproduction. Stop the music and reverse the poles of the tweeter on the crossover by exchanging the connecting cables (plus / minus). Listen to the music segment again and try to answer the question of which of both connections was louder. Repeat the experiment until you are completely sure.
The louder reproduction shows the correct polarity of the system
After the polarity has been decided upon tweeter level adjustment should be reconsidered.
Tips:

In the dark or with closed eyes the sound differences are usually more audible.
Use a complex instrumental music segment with several acoustic instruments for the evaluation.
