XCARD RESISTOR CHART

XCARD RESISTOR CHART

Our tests have shown that using 0.047mf capacitors for frequencies below 100Hz, and 0.022mf capacitors for frequencies above 100Hz, result in more linear crossover control. Refer to the Specifications page to determine the capacitor value of each supplied XCard.
