How is the wattage of a subwoofer with respect to the sine wave and pulse/music performance?
Mono subwoofer: The wattage (e.g. “360 W”) printed on the rear of the subwoofer near the mains plug designates the ability of the power amplifier “to pull” a maximum power rating in the specified range at the moment of switching on (those 360 watt stated as an example). Consequently, the wattage must correspond to at least the sine wave output of the amplifier, as this sine wave output must be permanently available which the power pack must provide as well. The pulse/music performance of the amplifier, on the other hand, can exceed the wattage, because the short pulses are buffered additionally by the capacitors in the power pack and are not achieved solely through the performance of the power pack. Multi-channel subwoofer: The wattage for a multi-channel subwoofer can also be below the sine wave output, as the specified sine wave output is not requested from every channel at the same time. For a 5 x 100 watt sinus power amplifier, for example, each of the five channels is able to impl
