§
Switch off the hi-fi system to perform the following test: inverting the polarization of the speaker. Listen to the
particular piece of music again. The tonal response should provide poor bass now. This effect can be heard if
the mono/stereo button on the amplifier is switched on. Therefore, please try mono mode. Do not forget to
switch back to stereo mode again later. If there is an inverse effect of the one described above, there is an er-
ror in regard of the polarization. This could result from the loudspeaker cables at the amplifier or at the loud-
speakers. Therefore, check the polarization of your loudspeaker. You can do this by means of a torch battery
(1.5…4.5 V). Connect the positive pole of the battery to the red terminal of the speaker and connect the nega-
tive pole to the black terminal. The woofer diaphragm should move forward now. If you can not eliminate the
error in polarization, replace the positive pole of one speaker cable with a negative pole. This way, the entire
hi-fi system should be polarized accurately.
§
Now check the connection of the two stereo channels. While listening to the test programme, turn the balance
control of your amplifier to the right and then to the left side. As a result, either the left or the right loudspeaker
is responding. If this is not the case, there is an error in the connection of the speakers with the amplifier ter-
minals.
§
By means of test records or test CD’s, you can control the connections at your amplifier (CD player, etc). If the
results of all tests are successful, the connection of the speakers is correct.
§
Define the place in your room where you would like to install your loudspeakers. Please switch off all compo-
nents, disconnect the speakers and route the cables in a way, o that tripping over is avoided.
§
After reconnecting the speakers, your hi-fi system is ready to run.

The last step shall help to optimize the positioning of the loudspeakers (please refer to the instructions given
in the previous chapters)
