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 ...

Have you ever wondered what makes a loudspeaker “difficult to drive”? Do you wonder what’s so special about an amplifier that is stable into a 4 ohm load? If these are the kinds of questions that ...

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 ...

As data-communication speeds increase beyond 3 Gbps, signal integrity becomes crucial for successful data transmission. Board designers try to eliminate every impedance mismatch along the high-speed ...

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 ...

Tonetti 3D-printed the custom two-microphone impedance tube to measure the saxophone acoustic impedance, while he 3D-printed ...

The question of time vs. frequency, as the most useful measurement domain, has long been a controversial topic. In some cases, it leads to rather heated discussions. The argument in favor of a vector ...

All engineers know resistance is usually bad news. It generates heat. It reduces efficiency. It wears out components and cuts operational lifetimes. However, resistance is not the only kind of ...

Impedance matching is easy if you know the basics. Download the eBook to find out how. The term “impedance matching” is rather straightforward. It’s simply defined as the process of making one ...

Ex-movie theater projectionist Steve Guttenberg has also worked as a high-end audio salesman, and as a record producer. Steve reviewed audio products for CNET and worked as a freelance writer for ...
