Zobel network calculator – Impedance equalization circuit – Step by step
Flattening the impedance curve A zobel network or an impedance equalization circuit is always a good idea when it comes to passive x-overs. Because impedance changes its value depending on frequency,…
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…
Speaker electrical characteristics – electricity basics
Electronics basics Before we discuss the speaker electrical characteristics, we need to clear up some of the most elementary properties of electricity. I know for some of you, this will…
Speaker spatial loading – sound radiation
What is spatial loading? Speaker spatial loading is determined by the boundaries which are in close vicinity of the object that radiates sound. This will determine a certain load. Similar…
Passive radiator speaker design – Box calculation example
What is a passive radiator ? A passive radiator speaker design involves another speaker, but with no motor assembly. The magnet and voice coil are gone, but the cone and everything…
