Frequently Asked Questions - Concentro M ELAC

What is the recommended placement for the Concentro M?

Place the speakers at least 30 cm from walls and angle them slightly towards the listening position. Optimal distance between speakers is 2–4 meters.

Can I use the Concentro M with a low-power amplifier?

Yes, but for best performance use an amplifier with at least 50 W per channel. The speaker handles up to 500 W.

How long does the break-in period last?

Allow 50–100 hours of playback at moderate volume for the drivers to reach optimal performance.

How should I clean the speaker cabinet?

Use a soft, dry microfibre cloth. For stubborn marks, slightly dampen the cloth with water and wipe immediately. Never use solvents or abrasive cleaners.

What is bi-wiring and should I use it?

Bi-wiring uses separate cables for the tweeter and woofer sections. It can reduce interference. Use two pairs of speaker cables or a bi-wire cable, and remove the jumper straps.

What is the warranty period?

ELAC offers a 5-year warranty for manufacturing defects. Registration may be required. Contact your dealer for details.

What room size is suitable for the Concentro M?

These speakers perform best in medium to large rooms (20–50 m²). In smaller rooms, careful placement and acoustic treatment may be needed.

How does the Concentro M compare to the Concentro S?

The Concentro M is the smaller floorstanding model with a 3-way design and JET tweeter, while the Concentro S is larger with additional woofers for deeper bass and higher output.

What is the JET tweeter technology?

The JET (Jet Efficiency Tweeter) uses a folded foil diaphragm to accelerate air, providing detailed and extended high frequencies up to 50 kHz.

What should I do if there is no sound from one speaker?

Check the speaker cables and amplifier connections. Ensure the bi-wire jumper straps are in place if not bi-wiring. Test with a different source or amplifier channel.

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.

2 Use only as directed

Connect the speaker(s) 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 speaker. For leveling on an uneven floor, unscrew the spikes or anti-slip feet by 2-3 turns of thread. The speaker should always 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

WARNING! Please ensure the product is perfectly stable to avoid injury from tip-over. Please note, that stability can be increased by using spikes on carpeted surfaces. However, the mounting of spikes must be carried out carefully due to their 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.
Do not install the speaker in a closed rack or in a closed cupboard.
Do not put burning candles on or near the speaker.
Do not install the speaker near transformers because electromagnetic stray fi elds can cause hum noise on woofers.
In combination with certain materials / lacquers / material surfaces, anti-slip feet or spike washers may cause colored imprints on the surfaces.

SAFETY INSTRUCTIONS

4. Overload

Extreme overload of the device due to very high volume may cause damage to individual components. 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 current! 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 onto 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 should be carried out by qualified service personnel only.

6. Cleaning

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 that you place an anti-slip mat underneath the loudspeaker(s).

7. Volume

CAUTION! Continuous high volume may cause severe damage to your hearing. Please listen responsibly.

8. Disposal

The packaging is made from recyclable materials. Dispose of this in an environmentally friendly manner. At end of 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(s) before disposal.

PHILOSOPHY

Thank you for purchasing this ELAC product.

Since the time we started (1926), ELAC has always striven to achieve the very best.

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:

Carefully unbox the speakers carefully to avoid physically damaging your speakers.
Use appropriate gauge wires (minimum of 12 gauge wire for runs up to 25 feet).
Make sure wire polarity is connected correctly. Most speaker cables are coded for ease of use. Make sure positive (red) connection on the amplifier terminal is connected to the positive (red) on your speakers. Follow the same instructions for the negative side. Strip off approximately 1/2" of the insulation from the ends of the speaker cable, twist the bare strands and insert into the binding post.
- Ensure your equipment is turned off before connecting speakers.
- Check to ensure positive and negative wires are not touching each other once they're connected to the speaker terminals.

AMPLIFIER

Bi-Wiring/Bi-Amping operation

Some of our speakers allow separate operation of the treble/midrange and the woofer by means of two amplifiers (Bi Amping) or by means of separate connecting cables (Bi Wiring). For this purpose, the speakers are provided with double terminals. The two pairs of connecting jacks that are provided with jumpers were designed for standard operation (with one amplifier). For Bi Wiring/Bi Amping, the jumpers must be removed. The passive crossover networks of the individual drivers remain in operation. This way, the use of special filter crossover networks is not required.

One pair of connecting jacks is used for the connection to the network of the midrange/tweeter. The other pair is used for the connection to the network of the woofer. Due to separate wiring (Bi Wiring), a decoupling of the two legs is obtained. This reduces cross-talking between the midrange/tweeter leg and the woofer leg.

There are different types of connecting cables that can be used. For example, low-inductance cables are suitable for the treble area and particularly large cables are suitable for the woofer area.

If both legs are operated through separate output stages, it is possible to choose amplifiers that allow the transmission of high, midrange or low frequencies. With separate volume controls for both legs, it will be easier to provide a sound balance that offers perfect adaption to the living room environment (room acoustics).

Please note, that different models of output stages may not provide the same volume when fed by one source through a y adapter.

The reason for this lies in different amplification factors that occur between the input and the output levels. To ensure, that the sound balance will not be defined at random, the amplifiers provide level controls that enable perfect adjustment of the desired sound balance.

It would be advantageous to choose a high-quality amplifier for one of the two stereo output stages.

Its volume control can be used to adjust the desired sound balance. The other output stage would be a puristic element that does not offer any adjustment options.

It is important to mention, that there must be prestages for adjusting the volume and programmes. If the prestige provides only one output, a standard cable for the Y adapter can be used.

ADJUSTING AID ELAC VX-JET

Your loudspeaker is equipped with ELAC's innovative VX-JET technology. This technology for the first time allows, to adjust the loudspeaker to your personal gusto and to special room conditions. By means of the adjusting knob on the rear baffle of the speaker, you are able to adjust the relation between direct sound (the sound which is directly distributed from the speaker to your ear) and reverberant sound (the sound which is distributed by reflections on walls and ceilings to your ear). So, you are not changing the sound of the speaker but its directivity pattern in the middle/high range. This paper should help you to adjust your speaker optimally.

In case your listening place is more than 4 m away from the speakers and you have a very spatial or reverberant sound impression, you should move the VX-JET to the inside (turning the adjusting knob out).

The mid position of the adjusting knob marks the neutral and basic position. This is suitable for listening distances of 3 – 4 m. The VX-JET is located in the same plane as the front of the loudspeaker.

n case the listening distance is less than 3 m and you have the impression that the sound is not spatial enough, you should move the VX-JET to the front (turning the adjusting knob in).

SPEAKER PLACEMENT

Achieve maximum performance and optimal sound quality from your ELAC speakers with proper speaker placement and set-up. While not all rooms are the same, use the following guidelines to configure the speakers for your particular room.

There are no “exact” rules or boundaries in setting up your speakers but the following suggestions will help optimize your desired results. Remember the best sound set-up is what sounds best for you so don’t be afraid to experiment and make adjustments to the placement and directivity of the speakers.

Place the speakers approximately one to two feet away (fi g. 1) from boundaries such as wall(s) and especially corners. Close proximity to a side or rear wall will enhance bass performance (output), but being too close (particularly to a corner) may result in bass that is unnatural. If a corner location is unavoidable, try to position the loudspeaker so that the distance to the rear wall is not equal to the distance to the side wall.

STEREO SETUP

For the best results and the most realistic stereo image and lifelike sound, place the speakers so that an equilateral triangle (fi g. 2) is created between the speakers and your favorite listening position. This set up creates the optimum imaging performance.

If you find that your front left and right speakers are too far apart, angle (toe in) them towards the listening position to gain a more focused central image.
