Measuring impedance with multimeter
@recluse Here, read this: https://speakermakersjourney.blogspot.com/2016/12/crossover-basics-impedance.html |
Thanks for all of the explanations and links. For non EE types, what sort of equipment would be needed then to get a reasonably accurate measurement? This? https://www.vellemanstore.com/en/peak-lcr45-lcr-and-impedance-meter?gclid=EAIaIQobChMI6YXV-MP83wIVmY... Thanks in advance |
If you connect your speaker to a signal generator and run a frequency response graph for the entire audio spectrum (generally 20-20,000cps) you can see on the graph how the impedance varies quite a bit (from maybe a low point of 2ohm to a high of over 20ohm) over the frequency range. The mfgr of your speaker states it is 12ohm but that is an average of the low and high impedance shown on the graph. You should connect your speakers to the 8ohm outputs on your amplifier. |
Bsmg, as I stated in the prior post, the graph provided by the maker of the speaker never dips below 12 ohms over the entire frequency spectrum. And I never mentioned anything about what taps I have. So is there no instrument that can be acquired without breaking the bank for nonEE to broadly measure impedance, or in this hobby where snake oils are rampant does everyone blindly except vendor claims? Speakers are expensive and impedance matters ;-) |
