Jantzen Audio 000-1123 | 0,51 mH | 0,495 Ω | 3% | 20 AWG

The Jantzen Audio 000-1123 air core coil is a premium-grade component designed for audiophile-grade loudspeaker crossover networks. Its 0.51 mH inductance and low 0.495 Ω DC resistance ensure minimal signal loss and accurate frequency filtering, making it an ideal choice for high-fidelity audio systems.

This coil excels in passive crossover designs for two-way or three-way speakers, where precise signal division between drivers is critical. It is particularly suited for tweeter and midrange circuits, where low distortion and stable performance are paramount. The air core construction eliminates core saturation and hysteresis effects, delivering clean, uncoloured sound reproduction even at higher power levels.

Technically, the coil features a ±3% tolerance for reliable inductance matching, while the 20 AWG wire diameter (0.81 mm) balances low resistance with manageable size. Measuring 33 x 15 mm, its compact form factor fits neatly into most crossover boards. The air core design ensures linear behaviour across the audio frequency range, preserving transient response and detail.

For enthusiasts seeking transparent crossover performance, this Jantzen Audio coil offers a cost-effective upgrade without compromising on quality. Its robust build and precise specifications make it a dependable choice for both DIY projects and professional speaker repairs.
