ADC 404

Sold or Listed Prices

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

Understanding the market

Half of recorded transactions fall between $49 and $99. The full range runs 2.0× from lowest to highest, which is normal for used equipment where condition, included accessories, and service history vary between units.

What buyers should know

Powered subwoofers fail at the amplifier module far more often than at the driver. Ask whether the amp has been serviced or replaced, and confirm the unit powers up and passes low-frequency material without distress. Shipping weight makes these expensive to move.

This range reflects 3 recorded sales, compiled from publicly listed and completed sales elsewhere on the used market, not from HiFi Registry transactions. Few units of this model reach the open market, which is itself useful to know: thin trading means published prices move further on any single transaction, and it usually means less negotiating room when one does appear. Treat this as an indication of where the model trades rather than a settled valuation.
