Dayton Audio DPR20-9.1 | 9.1 Ω | 20 W | 1%

The Dayton Audio DPR20-9.1 is a precision audio grade bifilar resistor offering a resistance of 9.1 Ω with a tight ±1% tolerance and a robust 20-watt power rating. Designed for the discerning audiophile and professional installer, this component ensures exceptional signal integrity and thermal stability in demanding audio applications. Its construction is tailored to maintain the purity of the audio path, making it an ideal choice for high-fidelity systems where accuracy and transparency are paramount.

This resistor excels in crossover networks for loudspeakers, where precise signal attenuation is critical for accurate driver integration and phase coherence. It is also well-suited for power supply filtering, load testing, and other audio circuits requiring low inductance and consistent performance under load. Whether upgrading existing equipment or building bespoke designs, the DPR20-9.1 delivers reliable, repeatable results.

Technically, the bifilar winding technique minimises parasitic inductance, preserving the resistor’s non-reactive behaviour across a wide frequency range. This ensures clean, transparent sound without coloration or phase shift. The ±1% tolerance guarantees tight matching between channels, while the 20-watt rating provides ample headroom for high-power applications. Housed in a durable, non-inductive package, this component offers long-term stability and low noise.

For precise, high-performance audio circuits, the Dayton Audio DPR20-9.1 is a dependable choice that combines engineering excellence with sonic purity.
