More often than not a question pops up in our forum about speaker impedance and the result of connecting multiple speakers to a single amplifier. Thus we have prepared this introductory tutorial to ...

I wouldn’t blame you if you assumed an 8 ohm speaker is always 8 ohms, but it’s not. Far from it, an 8 ohm rated speaker is actually 8 ohms only a small percentage of the time because the speaker’s ...

The impedance specification is ignored by most headphone buyers, but it might be one of the most important. Not that anything catastrophic will occur with an impedance mismatch, but you might not get ...

Audio specifications fall into two broad categories: Those that are nice to know, from an enthusiast or intellectual standpoint and those that are genuinely helpful in assisting you to use, install or ...

The phenomenon of resistance is observed with both alternating current (AC) and direct current (DC). That said, impedance is a more useful way to measure the resistance to electrons moving through a ...

If you are an old hand at RF design, you probably have a good handle on matching impedance. However, if you are just getting started with RF, [FesZ Electronic]’s latest video series on lossless ...

You’ve seen references to “impedance” and “ohms” in various loudspeaker specifications or in your owner’s manual for an AV receiver. But what is it? Do you have to “match” speaker impedance to your AV ...

In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...
