IXQ - Laminated Steel Core

PURITY GUARANTEERoHS Compliant

“Extreme audio performance with low losses”

ERSE’s line of IXQ laminated steel core inductors offers a lower distortion alternative to our IQ line of coils. Each coil is manufactured with ERSE’s exclusive PURITY GUARANTEE, offering the highest quallity possible.

The IXQ laminated steel core coil offers a micro thin low distortion grain oriented silicon steel. While our competitors are using 0.35mm thick steel we utilize 0.27mm thick grain oriented steel. The 30% reduction in steel thickness significantly reduces the eddy current losses, FM distortion and THD distortion. The IXQ core’s high grain cell structure is further more optimized by a specially developed annealing process. The combination of ERSE’s micro thin specialty steel and high purity OFC copper makes ERSE’s IXQ line of coils outperform our competition. Take the to see the Total Harmonic Distortion results. Custom molded high temp bobbins offer high insulation factor and have built in spacers for easy mounting.

All EQ inductors are lead free (RoHS Compliant)
