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 ...

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 ...

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 ...

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 ...

One way that Audioholics have presented on-axis and off-axis frequency responses in our loudspeaker reviews are through waterfall plots. Wikipedia defines a waterfall plot as: “a three-dimensional ...
