Polk Audio RT151

Sold or Listed Prices

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

Understanding the market

Half of recorded transactions fall between $80 and $90. The full range is tight — lowest to highest is only 1.5×, 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

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 5 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.
