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.

Die Nennbelastbarkeit des Lautsprechers, gemessen in W (Watt), gibt an, welche elektrische Leistung der Lautsprecher im Dauerbetrieb aufnehmen kann. 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.

Electrical impedance, or simply impedance, describes a measure of opposition to alternating current (AC). Electrical impedance extends the concept of resistance to AC circuits, describing not only the relative amplitudes of the voltage and current, but also the relative phases. When the circuit is driven with direct current (DC), there is no distinction between impedance and resistance; the latter can be thought of as impedance with zero phase angle. Impedance is defined as the frequency domain ratio of the voltage to the current.
