OPERATING INSTRUCTIONS
Safety Instructions
1. General information
• Please read and follow these safety instructions.
• Keep them safe for future reference.
• Observe all warnings on the speaker and in the manual. Please check the speaker for damage before
use. The speaker must be in perfect working condition. Damaged parts may lead to personal injury.
CAUTION! Subwoofers and active speakers are heavy. Be careful when lifting them to prevent
personal injury.
2. Use only as directed
• Connect this speaker according to the instructions in the manual.
• Many ELAC speakers are equipped with spikes and / or anti-slip feet. They are explicitly provided for
leveling the alignment. They have to be screwed into the thread until thread end. For leveling on an
uneven floor, it is allowed to unscrew the spikes or anti-slip feet by 2-3 turns of thread. The speaker has
always to be in perfect vertical alignment. The stability of the speaker must not be compromised by using
spikes or anti-slip feet as the speaker may tip-over .
3. Location
• Install the speakers on a level surface only
• When choosing the location of these speakers do not place them in locations that are:
• In direct sunlight
• Very humid
• Prone to vibrations
• Exceptionally hot or cold
• Near CRT Televisions (The speakers are not magnetically shielded and may cause color issues
with a CRT based TV)
• Close to magnetic cards (Since the speakers are not magnetically shielded placing magnetic
cards such as credit cards or commuter cards may cause them to fail).
WARNING! Please ensure the product is perfectly stable to avoid severe injury from tip-over. Please note, that
stability can be increased by using spikes for carpets. However, the mounting of spikes must be carried out
carefully because the spikes have very sharp ends which may cause injuries. The stability on slippery floors can
be increased by using Velcro fastening tape or double-sided adhesive tape. Do not install the speaker near any
heat sources such as radiators, heating valves, stoves, or other apparatus (including amplifiers) that produce
heat, or in areas where there is a risk of explosion.
• Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
• Don’t install the speaker in a closed rack or in a closed cupboard.
• Don’t put burning candles on or near the speaker.
• Do not install the speaker near transformers because electromagnetic stray fields can cause the
subwoofer(s) to produce humming noise.
• In combination with certain materials / lacquers / material surfaces, anti-slip feet or spike washers may
cause colored imprints on the surfaces.

4. Overload
Extreme overload of the device due to very high volume may cause individual components to blow.
Because of the possible danger, you should never leave loudspeakers under extreme overload
conditions unattended.
5. Service
DANGER! Do not open the cabinet because the components and conductors may carry dangerous levels
of electricity! Servicing to be carried out by qualified service personnel only.
Servicing is required when the loudspeaker has been damaged in any way, such as damage to
the power supply cord or the plug, or when liquid has been spilled or objects have fallen into the
loudspeaker, the speaker has been exposed to rain or moisture, does not operate normally, or has been
dropped. To reduce the risk of electric shock, do not open the loudspeaker. Servicing to be carried out
by qualified service personnel only .
6. Fuse links
Various faults in subwoofers or active speakers may cause the fuse to blow. If the fuse blows, only
replace it with the correct fuse type and rating as shown on the rear of the loudspeaker on the fuse
holder. A second fuse is included with the device (in the fuse holder beneath the mains socket).
7. Cleaning
NOTE: Clean only with soft, smooth cloth or with dust brush. Do not use scouring agents, alcohol,
benzene, furniture polish or other agents for cleaning! Modern furniture is often coated with multiple
varnishes and plastics which can be treated with chemical agents. Some of these agents contain
substances which degrade or soften the rubber feet. Therefore we advise you to place an anti-slip mat
underneath the loudspeaker.
8. Volume
CAUTION! Continuous high volume may cause severe damage to your hearing. Please listen responsibly.
9. Disposal
The packaging is made from recyclable materials. Dispose of this in an environmentally friendly manner.
At end of product life do not dispose of the speaker(s) with standard household waste. The speaker must
be recycled in accordance with local legislation. Ask your local government for further information on
recycling as the device contains valuable raw materials. Disable the speaker before disposal.
10. Power
This subwoofer is only intended to be connected to voltages that are listed on the rear panel of the
cabinet. Connection to any other voltage may cause irreversible damage to the subwoofer and will void
the warranty. Use of plug adapters is not recommended because they may allow connection to voltages
other than those printed on the back of this subwoofer.

Philosophy
Thank you for purchasing this ELAC product.
When we started in 1926, ELAC has always strived to achieve the very best. This holds true as much today as it
did back then.
Your new ELAC speakers are built to the highest standards using high-quality components that are carefully
constructed to deliver the best-in-class sound quality. They are developed by a passionate group of individuals
whose soul purpose is to bring a new dimension of sound quality into your home. Enjoy!
Before Use
Avoid damage to the speakers and other components:
• Unbox the subwoofer carefully to avoid physical damage
• Keep your equipment turned o before connecting interconnects or speaker cables
• Check to ensure power cable is pushed in and secured to avoid electrical shock and injury.
BASH Technology
The BASH® technology implemented in the amplifier module of the ELAC subwoofer features power reserves
with much lower levels of distortion. This is achieved by using an audiophile class A/B power amplifier whose
supply voltage is regulated by a class D amplifier circuit to prevent any unnecessary power losses and to obtain
the eciency of a class D amplifier.
Since the audio signal is amplified in the analog domain, the high-frequency interference typical of digital
amplifiers is eliminated. This design results in a low-noise amplifier with lower electromagnetic interference
emissions. The absence of crossover distortion, which is a problem in traditional class D designs where the
switching speed of the transistors is limited, yields further improvement in total harmonic distortion.

Installing Bottom Plates and Spikes
The SUB3070 comes with two steel bottom plates as well as a spike set that must be installed prior to use.
Please follow the below steps when unpacking and setting up the subwoofer. Due to the weight of the
subwoofer we highly suggest having a second person assist with this process.
1. Carefully unbox and remove the subwoofer from the box. Due to the weight of the subwoofer we highly
suggest using a second person. Place the subwoofer upside down on a soft non-abrasive surface.
2. Locate and place the steel bottom plates on the bottom of the subwoofer (The screw holes only line-up one
way) and secure with the supplied screws.
3. Now screw in the spikes as shown in the below diagram.
4. If you are installing the subwoofer on carpet, carefully turn the subwoofer over and adjust for the spikes to
level the subwoofer. You will need to use the metal locking caps to lock the spikes into place once leveled.
5. If you are installing the subwoofer onto hardwood, tile or other non carpet surfaces please use the supplied
spike discs to prevent any damage to your floor.

Subwoofer Placement
1
2
Finding the proper placement for your subwoofer can take some trial and error, however here are a few basic
tips to get you started. In most cases the best position for the subwoofer is in the front corner (1) of the room.
Placing a subwoofer in a corner excites most room modes and oers the best chance of avoiding a null area (a
part of the room that experiences an acoustic reduction in bass).
If placing the subwoofer in the corners creates an abnormal amount of bass, you can try moving the subwoofer
to one of the side walls (2) near the front of the room.
If possible the best option is to move the subwoofer around the room and find the location that sounds the best
from your normal listening position. There are many test discs you can purchase that provide the correct test
signals for helping find this optimum location.
Note: The PHASE and DELAY functions built into the subwoofer will also help if you experience any placement
issues.
Controlling Your Subwoofer—App Required
Your ELAC subwoofer incorporates an advanced, digital control system. Conventional analog rotary
potentiometers and switches (Except for Volume) have been replaced by a digital signal processor (DSP), which
enables you to adjust your subwoofer conveniently and accurately. All parameters, such as volume, cut-o
frequency, phase, etc., as well as the automatic calibration functions, can be adjusted with the help of a free
custom smart device APP.
The digital control system also eliminates the possibility of unwanted changes to controls and settings.
Note: A Bluetooth 4.0 low-energy Android or iOS device is required to set up and operate this subwoofer.
You can download the “ELAC SUB Control 2.0” APP from the Apple® App Store® or Google® Play Store®.
Please note that your mobile device must support Bluetooth® Standard 4.0. This is the case for the majority of
devices sold as of mid-2013. If necessary, check the accompanying documentation for your mobile device or
contact the manufacturer’s support hotline.
Note: In case your mobile device needs a 4 digit code during the subwoofer-pairing procedure, please use
“0000”
