Introduction
Tank you for buying a DLS design speaker system. Please read this manual fully before unpacking
and installing the product. It will help you to optimise the performance of your speakers.
Unpacking and maintenance
Your speaker should be treated with the same care you would treat a piece of furniture. Use only
a piece of soft cloth and a small quantity of warm soapy water to clean the loudspeakers. Avoid
touching the cone of the bass unit or treble dome since this may leave a finger mark or even
damage the dome and spoil its performance. After unpacking, we suggest you retain all packing
material for future transports.
Running-in period
The performance of the speaker will change subtly during the listening period.
Please allow your new speakers to play about 50 hours of music at normal listening level before
doing any critical listening.
Room positioning
The performance of a loudspeaker system in a room varies with placement. Ideal positioning of
the speakers are 2-3 metres apart and preferably at least 0.5 metres away from side walls. The
speakers must be installed hanging on the wall. You will experience the most accurate sound
picture if you listen from a position halfway between the loudspeakers, and 3 to 4 metres away.
Objects in the direct sound path can disturb the coherence of the sound picture. Try out different
positions before deciding on a final arrangement.
Mounting
The Flatbox M-One speakers have a"key-hole" on the back side for hanging the speaker on the
wall. Consider the weight of the speaker so that you use the correct type of bonding material.
Front cloth panel
Flatbox M-One speakers comes with cloth fronts in 7 different colors. The fronts can be easily
removed, just pull outwards, there are small magnets holding the front in place, make sure the
front is fixed in correct position. Choose the color that best matches your room interior.
For best sound performance the front cloth must be mounted.
NOTE!
All Flatbox On-wall speakers must be installed hanging on a wall. The good sound perfomance
of these speakers is obtained only when they are wall mounted.
