Jantzen Audio 000-1247 | 2,7 mH | 0,525 Ω | 3% | 15 AWG

The Jantzen Audio 000-1247 air core coil is a premium component designed for audiophiles and loudspeaker builders who demand uncompromising sound quality. This 2.7 mH inductor is meticulously crafted to deliver accurate crossover filtering, ensuring that your speaker designs achieve a natural and transparent audio performance. Its air core construction eliminates core saturation and hysteresis distortion, making it an ideal choice for high-fidelity applications where signal purity is paramount.

This coil is perfectly suited for use in passive crossover networks for two-way or three-way speaker systems, particularly in midrange and woofer circuits where precise inductance values are critical. It also excels in custom audio projects, such as rebuilding vintage speakers or designing bespoke hi-fi systems, where low-loss components are essential for maintaining sonic integrity. The 15 AWG wire gauge strikes an excellent balance between low DC resistance and manageable physical size, allowing for efficient power handling without compromising on clarity.

Technically, the coil offers an inductance of 2.7 mH with a tight tolerance of ±3%, ensuring consistent performance across production batches. The DC resistance is a mere 0.525 Ω, which minimises signal loss and preserves dynamic range. The coil measures 69 x 30 mm and is wound with 1.45 mm diameter wire, providing robust construction that withstands the demands of continuous use. As a Jantzen Audio product, it benefits from decades of expertise in audio component manufacturing, guaranteeing reliability and longevity.

Whether you are a seasoned DIY enthusiast or a professional speaker designer, this air core coil delivers the precision and transparency needed to elevate your audio projects to the next level.
