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

Understanding the market

Half of recorded transactions fall between $150 and $250. The full range runs 3.3× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.

What buyers should know

Check surrounds and tweeter domes for damage, and confirm the pair is matched — mismatched serials usually mean a replaced cabinet. Stands are rarely included and can add meaningfully to the real cost of ownership.

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.
