impedance measurement

FIXED: SEE POST #8 Hello. I built a dedicated box to measure both frequency response of loudspeakers and also impedance, I also do full dual channel FR measurements with amplifier. It's plugged like this when measuring speaker impedance with an amp: I found a nice discussion (cannot post...

Hello, I am a newbie. For impedance measurements I use Behringer U-PHORIA UM2, sense ceramic resistor 98.7ohm, and for reference I used three 100ohm ceramic resistors connected in parallel, the resultant resistance was 36,6ohm. I don't know how my impedance measurements are (in)correct...

Hello everyone. I've been using REW for quite some time and it's a very powerful software. I made my impedance measurement rig as described on the REW website and I used the headphone output and line input from my soundcard. However, I'd like to use an amplifier to drive the speakers for more...
