HIFIGUY Unregistered guest | Just for the heck of it, I took my Fluke meter, set it to read ohms and put the leads @ the voice coil terminals of a few speakers/subs...all of which are rated @ 4 ohms. Has anybody else tried this before? I did not get the 4 ohms that I expected. On the subs I got 3.0-3.3 and on the speakers I got 2.7-3.0. The reading fluctuated as opposed to staying steady. Is this normal or is something wrong with my meter/leads (brand new) or speakers (also brand new)? |

What you're actually reading is the speaker's DCR. That's usually lower than the nom impedance. |
