Default Multiple woofers testing

Hi,
I have an array of three 6.5" woofers in a ported enclosure. I suspect that only one of the woofers is working. I don't want to open the speaker. I'm trying to find a way to determine which one is working. I suppose I can set a mic next to each woofer and measure responses and compare them. I'm not sure the curves will be significantly different. Any ideas?

Thanks.
Alex

You could put a triple a battery across the terminals (briefly and carefully)

If only one is working, the others will flex and then rebound to neutral, but the working one will stay in the actuated position.

Why not play the array softly and putt your hear in front of each driver to listen to the working ones ?

Same louder and putt a finger softly on the cone ?

Or did you mean some are playing lower maybe ?

The battery test confirmed that all three woofers are active. I was not sure if all three were connected to crossovers.
