When selecting speakers, it’s common for people to just look at maximum power handling, and many manufacturers make a point of specifying seemingly unbelievable power handling capacity of 1000W or more. Its quite rare for manufacturers to specify power compression though, and it seems to be often overlooked by system designers. It seems that loudspeakers to […]

How do I know what impedance load I have? Most manufacturers will specify impedance, and will include it in the product specifications, often printing it on the speaker itself. If you don’t have this information, you can measure the DC resistance using a multi-meter (please note Resistance is NOT Impedance – find out why here: https://speakerwizard.co.uk/impedance-and-resistance-whats-the-difference/ […]

Why does my 8 ohm speaker read 6 ohms when I measure it on a multimeter? It must be faulty right? WRONG! I’ve heard this so many times I’ve lost count, but there is a difference between impedance and resistance. When you measure resistance with a multimeter you are measuring DC resistance. The DC resistance […]

Some of the basics of crossovers have been covered in this article: https://speakerwizard.co.uk/loudspeaker-basics-crossovers-why-do-we-need-them/ – here we will go into a little more detail of how passive filters work, and give you the tools to design your own. Crossovers and Filters Lets’s start with a reminder of the basics, a crossover is a combination of high […]

Nominal impedance (Z) is the simplified, rounded value used to describe a speaker’s average impedance across its frequency range. Unlike DC resistance (Re), which is a fixed value, impedance varies with frequency, often rising at resonance and at higher frequencies due to voice coil inductance (Le). Because impedance isn’t constant, manufacturers round it to standard […]
