Let’s start our expla nations of loudspeaker measurement graphs with the most basic graph of a speaker’s behavior: the frequency response. Sometimes this is referred to as the amplitude response as ...

What do we really mean when we talk about a loudspeaker’s “sound?” When we hear a speaker, how do we know by simply listening to it whether or not it’s a good speaker? What should we listen for?

How do you know if a speaker is any good? The answer should be obvious. If you like the way it sounds, then it is good. I’m not here to tell you what you like doesn’t actually sound good. But I am ...

A frequency response measurement reports the output levels of a DUT when stimulated with different frequencies of known level. The simplest of all frequency response measurements consists of only two ...

I was wondering if anyone knew of a free tool to plot a frequency response graph. Not from an audio signal, just from the raw data. I've got a ratshack spl meter, and I'd like to be able to plug the ...

Bode plots – or frequency response graphs – are found in just about every piece of literature for high-end audio equipment. It’s a simple idea, graphing frequency over amplitude, but making one of ...
