ETON POW 20+ / POW 16+

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 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 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 LEVELS OVER 130 dB. THIS MAY CAUSE DAMAGE OF HEARING. USE COMMON SENSE AND AVOID SUCH RISKS!

Volume and Driver Awareness

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 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 to disconnect 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 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

If 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 figure 1.

ATTENTION! If sheet metal must be cut or removed, contact your authorized car dealer for professional advice. Damage to supporting body structures may result in the withdrawal of the vehicle's operating permit.

Installing the tweeters

The tweeters can be flush- and surface mounted. Consider that repeated opening and closing of the car door can result in 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 figure 2.

Figure 2: Flush mount of Tweeter

Steps illustrated: Inserting the tweeter into a mounting bracket, rotating to secure, connecting cables, and final assembly. Includes cable color indication: Red (+) and Black (-).

The tweeter element can be turned and swiveled to achieve the optimum hearing path to your sitting position. See figure 3.

Figure 3: Tweeter 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 into the openings on the right and left of the element. Swiveling the tweeter allows it to be removed upwards. The speaker should be in the middle position!

Surface mounting:

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 figure 4.

Steps illustrated: Drilling holes, screwing the housing, and connecting cables to the tweeter. Includes cable color indication: Red (+) and Black (-).

Electrical 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 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.

IMPORTANT! Correct high frequency polarity in the vehicle

The correct polarity of 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, from 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, the operation of one channel (either left or right) is usually sufficient.

The correct polarity of the tweeter can be evaluated 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 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.

Connection Diagram

Figure 6: Wiring diagram for 2-channel / 4-channel

This diagram illustrates the overall system wiring. It shows connections from the AUTORADIO / SOURCE UNIT to the AMPLIFIER, and then to the Front System (two mid/woofers and two tweeters with crossovers) and the Rear System (two mid/woofers and two tweeters with crossovers). It is applicable for both 2-channel and 4-channel amplifier configurations.
