Dayton Audio DPR20-40 | 40 Ω | 20 W | 1%

The Dayton Audio DPR20-40 is a precision audio-grade bifilar resistor, meticulously engineered to deliver exceptional performance in high-fidelity loudspeaker systems. With a nominal resistance of 40.0 ohms and a power handling capacity of 20 watts, this component is ideally suited for use in demanding crossover networks, where accurate signal attenuation is critical to achieving a balanced and transparent soundstage. Its robust construction also makes it an excellent choice for audio enthusiasts building or upgrading passive filters, impedance matching circuits, or other signal-path applications where component quality directly influences sonic integrity.

Technically, the DPR20-40 employs a bifilar winding technique that effectively minimises parasitic inductance, ensuring consistent impedance and phase response across the entire audio frequency spectrum. The resistor offers a tight tolerance of ±1%, guaranteeing precise and repeatable performance in critical circuits. Housed in a durable, non-inductive package, it dissipates heat efficiently, maintaining stability even under sustained high-power operation. This combination of low inductance, tight tolerance, and robust power rating makes the DPR20-40 a reliable and sonically transparent choice for discerning audio builders. Whether used in a new design or as a premium upgrade, this resistor delivers the accuracy and consistency required for reference-quality sound reproduction.
