## Speaker lobing calculator – Polar response

When is speaker lobbing encountered? Speaker lobbing is a phenomenon which appears when there are 2 ore more speakers, that play the same frequency, and are of certain distance apart…

## Speaker impulse response explained – the basics

What is an impulse response (IR)? The speaker impulse response is something a little bit more complicated than it looks on the surface. You definitely have seen this term, if…

## Loudspeaker impedance measurement using a multimeter

How to measure speaker impedance? Making a loudspeaker impedance measurement is not a as easy as you might think. If you compare to resistance, impedance changes value with frequency. Therefore,…

## Notch filter design calculator – for speakers

How to flatten impedance curve using a notch filter design? A notch filter design is particularly useful when flattening the impedance of a tweeter. When it comes to speakers, there are…

## Speaker equivalent circuit / electrical model

What is an analogous speaker circuit? The speaker equivalent circuit is the actual core of the theories crafted by Thiele and Small. Every component of a speaker can be “transformed”…

## Speaker impedance curve explained with examples

What is impedance? Before we get the speaker impedance curve explained, let’s get down to the basics. When you apply a voltage, an electrical system will exhibit a certain amount…
