14 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $400 and $460. The full range is tight — lowest to highest is only 1.9×, which suggests these units trade in a well-established band and condition moves price less than it does for many models.
Over the last twelve months this model averaged $410 across 3 recorded sales, 6% lower than the preceding twelve months.
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 14 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. That is a large enough sample to price against with reasonable confidence, though condition and provenance still move individual units.
