| Re: Room EQ Wizard Doubles as Crossover Design/Measurement Tool
Put a 100 ohm, 10W resistor in series with your driver. Then connect the input of your sound card across terminals of the driver (in place of your mic/SPL meter). Make sure you turn off any mic/SPL calibrations curves, but be sure to use the sound card cal. Then you set up REW just like you would for a regular measurement and hit go. The graph that results has just measured impedance instead of SPL. Hope that was descriptive enough, but it's not too tough and works great for determining fs of a driver.
