8 ohm nominal impedance/4.69 ohm minimal impedance--is this a bad load (on paper)?


As per usual, I measure once and sometimes cut twice.  I am just curious, is all, as I am doing reading that I probably should have done back in May.  That impedance drop was what was listed by Ern's Corner for the Revel M126Be, and I was just wondering how it stacked up on paper.

4 Ohms or higher is usually "easy to drive" as even inexpensive integrated amps usually support 4 Ohms.  The combination of phase angle and impedance matters so it may require more current than apparent, but 4.7 is a pretty good speaker.  Honestly it's hard to find speakers that don't dip below 4 Ohms at least somewhere. 

On paper, a 4 ohm load is reasonable. BUT it all depends on your amp. The amp must be able to deliver sufficient current when the 4 ohm load is hit. I’ve seen name brand receivers shut down and poorly designed tube amps, with insufficient output transformers, severely clip under a 4 ohm load. So check your amp’s specs before you buy the Revel M126Be or any speaker.

+1erik. The minimal drop of 4.7 ohms is not unusual for a 8ohm nominal speaker. 

 

Phase angle is another spec to consider (aside from impedance) as the combo can make or break an amp.

Stereophile seems to measure both in the reviews I've read.
