Frequently Asked Questions - Arena S15 Sonus Faber

How do I connect the Arena S15 subwoofer to my system?

Use the LFE input if your receiver has a dedicated subwoofer output. Alternatively, use the L/R line inputs with a stereo RCA cable if connecting to a stereo preamp.

What is the best placement for the subwoofer?

Place the subwoofer on the floor near the front speakers, away from walls to reduce boominess. Experiment with corner placement for more bass but possibly less accuracy.

What crossover frequency should I set?

Set the crossover frequency knob to match your main speakers' low-frequency limit, typically 80 Hz for most systems. Adjust higher if your satellite speakers are small.

How do I clean the subwoofer cabinet?

Wipe the cabinet with a soft dry cloth. Do not use any liquids, solvents, or abrasive cleaners. For stubborn dirt, slightly dampen the cloth with water.

Does the subwoofer have auto standby?

Yes, the Arena S15 features auto standby that activates after a period of inactivity to save power. It automatically wakes up when a signal is detected.

What should I do if the subwoofer does not turn on?

Check the power cable and ensure the outlet is live. Verify that the power switch on the back is on. If it still doesn't power, try a different outlet or contact support.

Can I use this subwoofer with bookshelf speakers?

Absolutely. The Arena S15 pairs well with bookshelf speakers like the Sonus Faber Lumina or Sonetto series. Set the crossover appropriately for seamless integration.

What does the phase switch do?

The phase switch (0° or 180°) adjusts the timing of the subwoofer's output relative to the main speakers. Use the setting that produces more bass at your listening position, typically 0°.

What are the dimensions and weight of the Arena S15?

Dimensions: 420 x 420 x 450 mm (HxWxD). Weight: 18 kg. Ensure your shelf or floor can support this weight.

What is the warranty period?

The standard warranty for Sonus Faber products is 2 years from the date of purchase. It covers manufacturing defects. Register your product online for extended support.

1.2 - WARRANTY AND AFTER SALES SUPPORT

The loudspeakers are designed and manufactured according to the highest quality standards.

Check the complete Warranty Policy at www.sonusfaber.com/warranty-policy.

The following should also be kept in mind for your convenience:

- The warranty on the loudspeakers covers any manufacturing defects;

- Keep the receipt as proof of purchase to show to the retailer if necessary;

- Keep the loudspeakers' original packaging so that they can be transported without suffering damage if they need to be shipped to an authorized service center;

- The loudspeakers must be accompanied by a description of the malfunction or defect encountered.

The product warranty will be void under the following conditions:

- If the product has been disassembled or modified by persons other than a Sonus faber authorized service center;

- If the product has been used in a manner that is not consistent with the indications contained within this manual.

2. SAFETY INFORMATION

• This instruction manual must be read carefully and kept in an accessible location for any needs that may arise.
• Make sure that in-wall/in-ceiling fixing is suitably stable.
• Previously check that the capacity of the mounting surface is sufficient to support the weight of the loudspeaker/s.
• Avoid staying in close proximity to the loudspeakers while the audio system is operating at high volume. This can cause permanent damage to your hearing. Children must be kept at a safety distance of least 50 cm from the loudspeaker.
• The speakers generate an electromagnetic field that is harmless to humans and pets, but can compromise the proper functionality of electronic equipment, such as CRT monitors or TVs, when placed in close proximity. If this occurs, increase the equipment's distance from the loudspeakers.
• The technology underlying the speakers' functionality is based on the principles of electromagnetism, and the user should therefore avoid operating equipment that generates strong electromagnetic fields, as these could affect the loudspeaker's proper functionality.
• Do not connect the loudspeakers parallel to each other or directly to a constant voltage sound distribution system (100 V, 70.7 V or similar) without an adapter transformer. This could result in a serious system overload, with possible damage to the loudspeaker and/or the amplifier.
• Do not place audio cables and electrical power cables in close proximity to one another. An electromagnetic field is present in the vicinity of the power cables, which can cause an unpleasant humming noise. If this should occur, move the audio cables and electrical power cables away from each other.
• The connections must be made with the equipment turned off. Pay attention to the polarities of the terminals during connection.
• Connect the loudspeaker to a PS1 certified source pursuant to the IEC 62368-1 Standard.

3. INSTALLATION

3.1 - PACKAGING CONTENTS

• Speaker
• Frame
• Template for the hole
• Protective cover
  • Accessories box: fabric grids, screws, screw covers.

3.2 - UNPACKING

Respect the following general indications:

• It is advisable to open the packaging as close to the final location as possible.
• Use a proper tool to open the packaging. Do not insert the blade too deep to avoid damaging the contents.
• Keep all the packaging elements for any future transport operations.
• Do not wear any watches, bracelets, rings, etc., in order to avoid scratching the loudspeakers and their finishes. The same care must be taken in order to protect the loudspeakers from any metal elements present on the clothes you are wearing, such as zippers, buttons, belt clasps, rivets, etc.
• Check the content of the packaging. If one or more of the items is missing, notify the dealer where the product was purchased.
• Do not touch the drivers during the operation.

For the safe handling of the loudspeakers, it is strongly recommended to follow the instructions given in the table below:

Up to 44 lb A person
From 44 lb to 88 lb At least 2 people
From 88 lb to 132 lb At least 3 people
From 132 lb to 176 lb At least 4 people

Hold the loudspeaker securely with both hands in order to avoid dropping it.

The packaging materials can cause pollution. These materials must not be disposed of as domestic waste and must be brought to a waste collection and recycling center.

Do not leave the packaging materials within the reach of children! They could pose a risk of poisoning or suffocation if ingested.

If using a dedicated stand, do not use it with any speaker system other than the one for which it was designed. Improper use of the stand can result in damage or injury.

4. MAINTENANCE AND CLEANING

The loudspeakers do not require any particular maintenance operations, just general periodic cleaning.

It is recommended to use a soft brush to eliminate any dust that may have accumulated on the cabinet, the front panels, and the loudspeakers themselves, taking care not to damage the loudspeakers' delicate membranes.

It is recommended to use the supplied cloth and liquid to clean the metal and glass surfaces (where present). Do not use aggressive strong chemical products such as acetone, trichloroethylene, acids, abrasive agents, strong de-greasers, alcohol, lemon or wine. These measures will help you to keep your loudspeakers' working perfectly for years to come. Time will help improve the sound by breaking in the speakers' moving parts (membranes and suspensions), and the acoustic chamber will become accustomed to music being played the more it is used - much like what happens with acoustic string instruments!
