ass drums, organs, and electronic synthesizers are among the very few

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.
