Sold or Listed Prices

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

Understanding the market

Half of recorded transactions fall between $210 and $350. The full range is tight — lowest to highest is only 1.8×, which suggests these units trade in a well-established band and condition moves price less than it does for many models.

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 7 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.
