Understanding the market

Half of recorded transactions fall between $99 and $150. The full observed range is unusually wide — the highest recorded price is 22.2× the lowest. A spread that wide usually means the recorded sales are not strictly comparable: different configurations or finishes, units sold for parts or with cosmetic damage, or listings where the model name is shared across more than one variant. Treat the middle range as the useful signal and the extremes as outliers worth investigating before you price against them.

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 13 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.
