Important – Please Read First
ass drums, organs, and
electronic synthesizers are
among the very few
B
instruments that produce
extremely low-frequency sounds.
As a result, comparatively few
home loudspeakers are designed
to reproduce bass below about
50 Hz.
T oday, however, home
loudspeakers are called upon to
reproduce more than music: in
home theater systems, they are
called upon to reproduce movie
soundtracks. And modern
movie soundtracks contain a lot
of energy at very low frequencies—on sound effects.
T o do full justice to these
effects, as well as to the musical
low-frequencies missed by most
speakers, the Cambridge SoundWorks Powered Subwoofer II
reproduces, at high power, the
lowest bass sounds the human
ear can detect.
Y ou should keep in mind
when installing your Powered
Subwoofer II and investigating
its capabilities that you will be
dealing with a relatively
unfamiliar range of sounds.
These are sounds more felt than
heard, and are encountered
more often in the well-equipped
movie theater than in the
concert hall.
