Harrison Labs · XLR Series
Every XLR inline crossover filter is available at the same standard crossover frequencies as the FMOD series, with no color-band coding. Tap a frequency to see its exact −3dB spec at 10K and 47K ohm loads.
How to read this: the standard crossover frequency shown is the −3dB point, standardized at 22K ohms. Expect an 8% (LP) / 25% (HP) increase at 10K ohms, and an 8% (LP) / 15% (HP) decrease at 47K ohms.
