This video shows how to measure loudspeaker impedance using SignalScope X and Dayton Audio’s DATS V2. It highlights SignalScope X’s MultiTool and Dual FFT Analyzer. First, the DATS V2 is configured and calibrated with its included 1kOhm resistor. Then, loudspeaker impedances can be measured and compared very quickly.

» Read moreToday, a new video, Measuring Loudspeaker Impedance with IOScope, was published on this site, as well as on the Faber Acoustical YouTube channel. The video is both a demonstration of IOScope, as well as a simple tutorial on measuring loudspeaker impedance. Although the video is largely self-explanatory, I thought it would be beneficial to include some further explanation and tips for those who are interested. The movie is essentially broken into four chapters and a similar format will be followed here. What is impedance? How is it measured? By a generalized version of Ohm’s law, we understand that voltage is equal to the product of electrical current and impedance. This means that electrical impedance is equal to the ratio of […]
