Sold or Listed Prices

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

Understanding the market

Half of recorded transactions fall between $53 and $58. The full range is tight — lowest to highest is only 1.2×, 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 10 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.
