Hello everyone, I am rebuilding some Coral 3-Way speakers. There is one component I am curious about. Not sure if it is a resistor or inductor.
I measured it and it has a DCR or 9.5 ohms. I am thinking it is a resistor since a inductor would have a DCR of 9.5 ohms. The component is hollow though.

It even says 10 ohm right there on it... Resistor!!
The reason it's hollow is that it's wound on a ceramic tube to allow for better heat dissipation. This is/was a pretty common practice for wire-wound resistors.

Thanks everyone, I thought so. It just looks so much like an inductor and it is on the midrange, so it was possible. I wouldn't think an inductor would have a DCR of 10-ohms.
Lots of inductors could have DCR's of 10 ohms. They range from less than one ohm to greater than 1k ohm. Point is, this one isn't an inductor based on the construction, regardless of the labeled or measureable parameters.
Typically, an inductor is labeled in henries and possibly amperes; a resistance value is much less common, and would only be included in addition to henries.
