Subwoofer- / Satellitenanpassung

Ich fand beim Recherchieren folgenden interessanten Text:

Conventional powered subwoofers receive their input signal directly from their crossover before the main amplifier.

The sonic signature of the main amplifier that is an important part of the sound you hear from the full-range speakers, is missing from the subwoofer.
This causes blending and integration problems as the sonic characteristics of the system are different above and below the subwoofer crossover point. This deterioration of system coherence is why conventional subwoofers have never been totally accepted as part of ultra high-performance audio systems.

The second reason for a poor blend is that the main speakers do not have the bass extension necessary for a linear transition. Basic filter theory dictates that the main speakers must have predictable response at least an octave below the crossover point to insure proper blending with the subwoofers. For an 80Hz subwoofer crossover point, the main speakers must have predictable response to 40Hz or lower. This is why it is difficult to successfully mate subwoofers with mini-speakers - the limited-range small speakers simply cannot reach the required full octave below any reasonable subwoofer crossover point.
