This is a common issue due to failure to remove, or insufficient removal, of the coil wire's enamel coating prior to soldering.

I had the enamel off okay. I must have soldered it with a pencil iron and didn't get the joint hot enough.

One of the speakers was wheezing a bit when I played them. I noticed the surround was not attached entirely. There isn't much material there either as in maybe too small. I reattached with E6000 adhesive. These were labeled "Precision Audio" on masking tape around the magnet.
