Polk Audio CS150
Price trend
22 months of data shown — Listing Comps build richer history as transactions accumulate.
Sold or Listed Prices
5 market transactions via web search — not HiFi Registry sales.
Understanding the market
Half of recorded transactions fall between $49 and $49. The full range is tight — lowest to highest is only 1.6×, 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
Confirm the centre matches the timbre of the main speakers in the same line; a mismatched centre is the most common cause of poor dialogue integration. Check driver surrounds as you would any speaker.
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.
