A logical use of audio filters is to attempt to “match” the frequency response of a microphone, loudspeaker, amplifier, or room to that of another. Can this really work? Let’s look at when it can, and when it can’t.
There are many ways to make a system sound better, and frequency response matching can be one of the tools in your tool bag, but as is almost always the case, the devil is in the details.

Using these “truth tellers” to address some common system tuning problems.
Even though two-channel designs are the most popular form factor, the majority of sound reinforcement systems aren’t stereo. But having two amplifier channels in the same box can provide some other benefits. So, “What’s the carrot?”
Using these “truth tellers” to address some common system tuning problems.
Investigating timing issues as well as frequency response magnitude, frequency response phase, EMI susceptibility, common-mode rejection ratio (CMRR) with a lineup of mixers.
Here’s a handy quiz for checking your knowledge about audio power. Know that right upfront, the answer to every question is “It depends!” But what’s really being asked is “WHAT does it depend on?”
Understanding the strengths and weaknesses of each type of amplifier and selecting one that makes sense for the application.
Addressing common misconceptions about transformer-distributed loudspeaker systems.
This method is best understood by looking at the workings of a traditional power amplifier.
