One of my speakers sounds like it's underwater.

I still think the difference is significant. If you measure across the speaker terminals, then you measure the VC resistance plus the DC resistance of the woofer series inductors. So both speakers should have the same DC resistance. This is just the sort of discrepancy you get when a VC is fried, but not open circuit. The insulation brakes down on the copper wire in the VC and starts shorting some of the VC wire turns, lowering the DC resistance. The VC starts to unravel and there are also carbon deposits in the gap, which can produce strange effects. So you can be pretty certain the VC of that woofer is fried. The tweeter will have caps in series and so the DC resistance of the high pass will be infinite and not contribute to the DC resistance of the speaker.

But, and it's a very big butt...it appears he measured on the back of the speaker cabinet. (the input terminals) , based on his statement he might take the woofer out and remeasure. (I had a suspicion he was doing this)

He can measure till the cows show up...he needs to have that woofer reconed.

This comes down to trying to figure out what the heck is wrong without seeing things for ourselves, and trying to make sense of what someone elses description is all about. (about 90 percent of what we do here )

I assumed he measured at the speaker terminals, as if the drivers are in place that is the only way he could have measured a DC resistance. I agree that woofer needs a total rebuild. So he needs a cone with VC attacked, a dust cap, surround and shims to factory specs to set the VC gap correctly. He also needs a tube of speaker glue.

This vid skips over the cleaning the frame process, which can be messy sometimes.. The link I gave him supplies the parts...minus the glue.
Been a long time since I reconed !

Okay sorry been a busy cruddy week , but nobody died , so can't complain. Well I took both of the speakers out and measure the resistance on them. Both measured 5.9. then I checked the crossovers and it looked like a few of the wires were touching. I separated the wires and tried the woofer again. It made no difference. The speaker still popped and distorted.

I then swapped the woofer and put it into the other cabinet. I thought maybe it would make a difference or at least narrow down the issue for me. The speaker, woofer, popped and distorted just the same. I have not put the good woofer in the other cabinets, but speculating it will sound the same as it did and the cabinet that it came out of. I will report back on this shortly after work however.

But as of right now it looks like the woofer is the problem. They both measure the same ohm wise.

The woofer obviously has a voice coil problem and needs reconing.
