⚽ Sony SS-WS551 Home Theater Surround Sound Passive Subwoofer

This standalone passive bass speaker was originally part of Sony’s all-in-one "Dream System" 5.1 channel DVD home theater bundles from the mid-2000s. Because it runs at a low 3-ohm impedance, it is highly recommended to only use it with its original matching Sony receiver component or an amplifier rated safely for low-impedance loads to avoid overheating your equipment.
