Polk Audio PSW10 Powered Subwoofer (not authenticated)

This item is the rear panel of an electronic audio component, specifically appearing to be a Polk Audio PSW10 Powered Subwoofer. The unit features a black cabinet construction with a prominent black metal control and input plate secured by multiple screws. Physical characteristics include a power cord exiting the lower left, an integrated volume control dial marked from min to max, a low pass crossover frequency knob adjustable between 80Hz and 160Hz, a power switch with ON, AUTO, and OFF positions, a phase switch for 0 degrees and 180 degrees, and line-in RCA jacks for left and right channels. Additionally, there are spring-clip terminals for speaker level output and speaker level input connections for both right and left channels. Notable markings and text printed directly on the metal panel include the Polk Audio logo with the tagline 'the speaker specialists' followed by 'POWERED SUBWOOFER', safety warnings in English and French, UL listing information, electrical specifications indicating 120V 60Hz 100 Watts, and a manufacturing date marking reading 'MFR. DATE: Jan 2014'. A white sticker near the top right displays a barcode and reads 'MODEL: PSW10 110V' and 'SERIAL #: AM1055389707', and another small sticker near the top left reads 'MODEL: PSW10 BLK 110V'. The visible condition of the metal plate and surrounding black cabinet appears clean with minimal wear and no obvious major structural damage or repairs visible. The identification rests on multiple clear printed brand names, model numbers, and technical labels directly visible on the control panel and stickers. The style is consistent with consumer home audio equipment from the 2010s, utilizing standard analog control interfaces and connection terminals.

Based on the provided image of the rear panel, I am evaluating what appears to be a Polk Audio PSW10 Powered Subwoofer. The control plate bears markings consistent with Polk Audio and indicates a manufacturing date of January 2014. From what I can see in the photograph, the exterior condition of the cabinet and metal plate appears clean with minimal wear. However, I cannot evaluate the internal electronics, the condition of the front speaker cone, or whether the unit actually powers on and functions correctly without a physical inspection and testing. The Polk PSW10 is a widely produced, entry-level consumer audio component from the 2010s. Market demand for this specific model is consistent but heavily saturated, as it was a popular budget option for home theater setups. Typical secondary market values for functional, pre-owned units of this type generally fall in the $40 to $80 range, assuming full functionality. Since I cannot physically test the audio output or inspect the driver, this estimate assumes the unit is fully operational. If the item requires repairs, has a damaged amplifier, or features a blown speaker cone, the value would decrease significantly, likely falling below $20 for parts. To further validate this working assumption of its identity and operational status, an in-person examination and a live audio test would be required. While consumer electronics of this entry-level tier are rarely counterfeited, this estimate remains contingent on the piece functioning exactly as the exterior markings suggest.
