Powered / Active
Powered/active status identifies whether a product includes its own power amplification or needs an external amplifier.
A passive product relies on external power amplification. A hybrid can combine a powered bass section with a passively driven upper range; the label here describes amplification provision.
Powered / Active — Subwoofer
For a subwoofer, active status means its amplifier is built into the product. A passive subwoofer needs a suitable external amplifier and the required crossover arrangement elsewhere in the system.
Compare the signal inputs and controls available on the actual model. A speaker-level input on an active subwoofer does not make it passive; the built-in amplifier still drives its woofer. Keep power-output ratings and mains consumption separate from the active/passive label.
Powered / Active — Loudspeaker
For a loudspeaker, built-in power amplification changes the connections needed from the rest of the system. A hybrid design can still require speaker-level drive for its passive section as well as power for its built-in amplifier.
Compare the actual input and power arrangements. Built-in amplification does not automatically include volume control, streaming or wireless connectivity. Keep amplifier power and crossover topology separate from this status, and do not assume a powered version’s features apply to a passive variant.
Powered / Active — Super Tweeter
For a super tweeter, this status determines whether the driver is powered by built-in amplification or connected to an external amplifier through the specified arrangement. Passive add-on units can connect within an existing speaker system.
Compare the intended connection and filtering requirements before integration. A level-adjustment control does not prove that an amplifier is built in. Active status also does not establish wireless operation or remove the need to match the super tweeter’s operating range with the main speakers.
