Subwoofer properties


Subwoofer properties

A subwoofer (or "sub") is a woofer, or a complete loudspeaker, which is dedicated to the reproduction of low-pitched audio frequencies known as bass. The typical frequency range for a subwoofer is about 20–200 Hz for consumer products, below 100 Hz for professional live sound, and below 80 Hz in THX-approved systems. Subwoofers are intended to augment the low frequency range of loudspeakers covering higher frequency bands.

Sie wird mit einem definierten Rauschsignal ermittelt. Dieses Rauschsignal soll ein typisches Musikprogramm simulieren. Es ist dadurch gekennzeichnet, daß die hohen Frequenzen viel schwächer vertreten sind als die tiefen.
