Sold or Listed Prices

34 market transactions via web search — not HiFi Registry sales.

Understanding the market

Half of recorded transactions fall between $50 and $80. The full observed range is unusually wide — the highest recorded price is 210.0× 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

Inspect drivers and surrounds before anything else — foam surround rot is the most common failure on older floorstanders and is not always visible in photos. Ask whether the cabinets have been re-veneered, whether the crossovers have been recapped, and confirm both cabinets came from the same production run. Shipping is the other major cost: large floorstanders often need freight rather than parcel, and original cartons materially affect both safety and resale.

This range reflects 34 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.
