Set-up tips

A larger distance is better (i.e. a position behind the main speakers up to approx. 1 m, or from special subwoofer out-
puts and with reproduction of surround video effects up to 3 m.)
In addition to the maximum sound pressure, the bass quality can be improved by using a pair of ELAC subwoofers. If
both subwoofers are connected by one source (mono), the second unit should be placed asymmetrically to all the
other loudspeakers, not directly beside the first one. This will ensure an even and less resonant bass, typical of large
open rooms, can also be achieved in small rooms. If however, two subwoofers are operated in true stereo mode, they
should be placed at about the same distance from the respective main speaker and the listener, with a maximum dif-
ference of 0.5 - 1 m depending on the crossover frequency. Where two ELAC subwoofers are playing in parallel (or
stereo), both should be adjusted equally. With some digital sound formats (e.g. Dolby Digital) all channels, including
the rear ones, are driven with the full dynamics and bandwidth, even frequencies in the sub-audible ranges are often
transmitted. Thus, you may find that the rear channels perform better with a subwoofer of their own. For this, the uni-
versal connection options of the ELAC subwoofer can be used. In larger rooms, the set-up of a second or third sub-
woofer may also be useful, depending on the size and model.
