ACTIVE/PASSIVE
With a passive loudspeaker, the signal from the amplifier is divided into three
frequency bands, (bass, bass/mid and treble) by a passive filter built into the
loudspeaker cabinet. This is powered by the signal itself, absorbing some of
the amplifier power, and preventing the amplifier from accurately controlling
the loudspeaker.
Although the highest quality components are used in Linn loudspeakers,
they have to handle extremely high power without overheating, and are less
suitable for handling the fine details of music.
An active crossover does not make these compromises. It accurately divides
the signal from the preamplifier into three frequency bands, and feeds each to
its own power amplifier. The loudspeaker drive units are directly controlled by
the power amplifiers. The low power of the active crossover means better
filtering, and accurate amplitude and time response correction for the KABER
loudspeaker.
