Frequently Asked Questions - Speaker Box 10 S2 PRO-JECT

What type of amplifier can I use with these speakers?

You can use any good quality amplifier with an output impedance of 4 to 8 Ohms. Avoid low-power amplifiers used at high volume, as clipping can damage the speakers.

How to connect the speakers?

Ensure the amplifier is turned off. Connect the red terminal of the speaker to the red terminal of the amplifier, and the black terminal to the black terminal. Do the same for the other channel. Connect only one speaker per terminal.

How far should the speakers be placed from the walls?

Place the speakers at least 50 cm from the back wall and 1 meter from the side walls to optimize sound reproduction.

What spacing between the two speakers?

At least 2 meters spacing is recommended. In a living room, 2 to 4 meters generally gives good results.

What should be the distance between the listener and the speakers?

The listening distance should be at least equal to the spacing between the speakers, and ideally larger for a good stereo effect.

Can I use these speakers with a low-power amplifier?

Yes, but avoid turning the volume up to maximum. Low-power amplifiers in clipping can damage the speakers. Reduce the volume if you hear distortion.

How to maintain the speakers?

The speakers do not require any regular inspection. No particular maintenance is needed.

What to do in case of problems with the speakers?

Contact your dealer. Parts are not user-serviceable.

Can I connect multiple speakers to a single amplifier output?

No, connect only one speaker per amplifier terminal to avoid damage.

How to get a good stereo effect?

Respect the recommended distances: 50 cm from the back wall, 1 meter from side walls, 2 to 4 meters spacing between speakers, and listening distance at least equal to that spacing. Try different placements while listening to music.

Dear music lover,

You have just purchased one of the best domestic hi-fi loudspeakers available and we hope you will enjoy the music they reproduce for many years to come. Before connecting your loudspeakers and to achieve maximum performance and reliability you should study these instructions for use carefully.

Safety instructions

Avoid spilling liquids on speaker, connection terminal or speaker cable. Never place any item containing liquid such as a flower vase on or near the device. Never place any naked flame sources, such as lighted candles on or near the speakers. The product shall not be used in damp or wet locations, next to a bathtub, sink, swimming pool or any other similar conditions.

Unpacking

Both loudspeakers are packed in one cardboard box and contains all necessary parts:

2 Speaker box 10S2 floorstanding speakers

8 Spike feet with counter spike discs

Step 1: Place Speaker Box 10S2 upside down (ideally on a carpet, not to scratch top surface).

Step 2: Mount all 4 spike feet

Step 3: Place speaker Box 10S2 with spikes onto the floor (spike discs can be added to avoid scratches on the floor)

Loudspeaker positioning

Ideally both loudspeakers should be positioned at same level (tweeter in about ear level) and in same distance from the listener, at least 50 cm from a rear wall, 1 meter from a side wall and ideally forming an equilateral triangle – see page 3 of this manual. If loudspeakers are placed too close to each other or too far apart, stereo images will not be fully developed. The listeners distance from the loudspeakers should be at least equal to and preferably greater than the distance between the loudspeakers. Tests should be made with both speech recordings and music before deciding upon final locations.

Amplifier capacity - power handling

Your loudspeaker system will operate satisfactorily with any good amplifier designed for use with an 4-8 Ohm impedance load. Although loudspeakers are designed to handle high power loadings, you must remember that any loudspeaker that is abused with excessive use of volume, tone controls and graphic equalizers is likely to cause damage to the drive-units. Be careful especially with small amplifiers constantly driven on high power levels, as these may be liable to go into „clipping mode" and distort the signal causing possible damage. If you hear a distorted signal through the loudspeakers you must reduce the power level.

Connecting to your amplifier

We strongly recommend the use of high quality speaker cables, colour coded or grooved cables are recommended to assist checking polarity, your local dealer should be able to advise you on this point. Always switch OFF your amplifier before making any connections or adjustments to the system. Wire the right-hand channel cable so that the positive (RED) terminal of your loudspeaker is connected to the positive (RED) on your amplifier, and the negative (BLACK) terminal of your loudspeaker is connected to the negative (BLACK) terminal on your amplifier. Repeat the instructions for the left-hand channel. Do NOT connect more than one loudspeaker to one terminal on your amplifier.

Please set the volume level to minimum before switching on the amplifier!

Phasing

Providing that you have followed the connecting instruction correctly the loudspeakers should be in phase and provide solid stereo images. If however, you have any doubt as to the phasing of the loudspeakers, try reversing the connections (RED & BLACK) to ONE of the loudspeakers, and play a recording which has plenty of deep bass operating both loudspeakers simultaneously with the stereo amplifier switched to „mono". The correct polarity is indicated by firm full bass, when incorrect, the bass will be noticeably much weaker.

Service

No routine attention is required to the working parts of the loudspeakers and being very reliable loudspeakers rarely require service. Any service problems should in the first instance be referred to your dealer.
