View Full Version : JBL D131 ohm ratings?

07-29-2008, 07:07 AM
Hey guys,

I'm looking to buy a pair of d131's and I've run across what looks like a nice pair....the gentleman says they are 16 Ohm speakers and yet the drivers were tested and rate 7.5 and 7.2 ohms...

Does this sound right? Sorry I'm a newbie!

Some of the older JBL driver units were listed as 8 ohm and 16 ohm but actually were not.

Hope this helps!

Regards, Ron

Re is spec'd at 6.3 ohms (+/- some value), so a little higher doesn't seem
wacky :)

As well, the DC resistance measurement is not the same as the AC impedance presented to the crossover/amplifier and this varies with frequency. This article will help:
