Power Compression

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 […]

Impedance – FAQs

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/ […]

Impedance and Resistance – what’s 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 […]
