The use of subwoofers leads to a multiple increase in the dynamics of your audio system.
To safeguard your tweeter systems, we recommend protecting these with an additional
protective condenser (100 - 200uF series-connected in front of the overall mid-tweeter
system).
THE FOLLOWING POINTS SHOULD BE HEEDED WHEN CHOOSING
COMPONENTS:
• Although core coils offer a good price-performance ratio, they also penetrate the
saturation region, which results in acoustic distortions. The coils should therefore have
as little ferrite / iron content as possible.
• Be sure to adhere to the recommended minimum cable diameter.
• With regard to condensers, electrolyte condensers with the highest possible electric
strength should be used.
• The components should not be mounted directly on the speaker. Secure the parts with
screws, cable ties and hot-setting glue. Keep the cable runs as short as possible.
• The components are available from specialist electronic equipment dealers.
CABLES TO BE USED
To transport the output from the amplifier to the subwoofer efficiently and reliably, you
should bear in mind when selecting the speaker cable that 2 x 4 mm² gauge wiring is
required for cable lengths in excess of 3 meters. 2 x 2.5 mm² cable is sufficient for shorter
runs. Lay the cable in such a way that short-circuiting cannot occur, i.e. the cable may at
no time be jammed between metal parts. Make sure that terminals on the speaker are
screwed tight and check their contact at regular intervals.
