Understanding the market
Half of recorded transactions fall between $85 and $115. The full range runs 4.0× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.
What buyers should know
Powered subwoofers fail at the amplifier module far more often than at the driver. Ask whether the amp has been serviced or replaced, and confirm the unit powers up and passes low-frequency material without distress. Shipping weight makes these expensive to move.
This range reflects 5 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. That is enough to establish a working range, but not enough to be precise — treat it as a guide rather than an appraisal.
