AR90 tweeter and UM ohm readings


Recommended Posts

I picked up a tweeter and Upper Mid off of eBay to have as a spare for my 90s should anything go wrong.

The drivers were very will packaged. The tweeter looked like new and the UM had a bit of what's probably dried ferrofluid at the center of the magnet.

I took a DC resistance of each driver.

Tweeter> 1.4 ohms

UM> 3.4 ohms

The tweeter reading bothers me. Can anyone tell me if either are good to keep and use???

Is this a normal/typical ohm resistance reading for the tweeter???
