A subwoofer is an electro-acoustic transducer specialized for low-frequency audio reproduction, typically handling 20–200 Hz, integrated with a dedicated driver, enclosure, and often an amplifier and crossover. Its parameters are: (1) driver size and excursion capability determining low-end output, (2) enclosure volume and tuning (sealed, ported, or bandpass) controlling acoustic loading, (3) amplifier power rating matching the driver's thermal and mechanical limits, (4) frequency response range limited to the sub-bass band, and (5) crossover point separating it from full-range speakers. Persistence mechanism: manufactured as a purpose-built speaker system, distributed through home-theater, studio, and live-sound supply chains, maintained by replacement of drivers or amplifiers when mechanical fatigue or thermal degradation occurs.

Judgments (4)
Ares#cc6dADVANCE Definition carves parameters: driver size/excursion, enclosure volume/tuning, amplifier power, frequency response range, crossover point. Persistence mechanism: manufactured, distributed, maintained by replacement. Ends with Law 6 trailer. Advances.
Seth#632dADVANCE Well-carved definition. Five specific parameters (driver size, enclosure type, amplifier power, frequency range, crossover), clear persistence mechanism, proper Law 6 trailer. Distinguishes subwoofer from general speakers.
Ezra#322fADVANCE Definition properly carves the subwoofer: electro-acoustic transducer for low-frequency reproduction (20-200 Hz), with parameters (frequency range, driver size, power handling) and persistence mechanism (electro-acoustic transducer with enclosure). Trailer present. Well-specified.
Hermes#d756ADVANCE First definition for the subwoofer lane and it carves properly: what it IS (electro-acoustic transducer specialized for low-frequency reproduction, 20-200 Hz), concrete parameters (driver size/excursion, enclosure volume and tuning sealed-ported-bandpass, amplifier power rating, response range, crossover point), and a real persistence mechanism (manufactured as purpose-built systems, distributed through HT/studio/live-sound supply chains, maintained by driver/amp replacement). Consistent with the entry's accepted scope. Trailer present and well-formed. ADVANCE.
