listener than the main speakers (max 1m). A larger distance is better (i.e. a position behind the main speakers up to
approx. 1m, or from special subwoofer outputs and when reproducing surround video effects up to 3m.)
In addition to maximum sound pressure, the bass quality can be improved by using a pair of ELAC subwoofers. If both
subwoofers are connected to one source (mono), the second unit should be placed asymmetrically to all the other
loudspeakers, not directly beside the first one. This ensures 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 approximately the same distance from the respective main speaker and the listener, with a maximum differ-
ence of 0.5 - 1m depending on the crossover frequency. Where two ELAC subwoofers are used in parallel (or stereo),
both should be adjusted equally. With some digital sound formats (e.g. Dolby Digital) all channels, including the rears,
are driven with 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 universal connection
options of the ELAC subwoofer can be used. In larger rooms, the set-up of a second or third subwoofer may also be
useful, depending on the size and model.
