I took a chance and bought a pair of 128H woofs that were reported to have been "recently re-foamed". Well they were, with the wrong surrounds. They were too wide, as near as I can tell. On arrival, both cones were very low in the basket, one was bottoming out with very little downward force, maybe 1/4" movement or less. Looking that the brown part underneath, (yes, I am ignorant of the terms), the spider or whatever it's called, I could see it was depressed a long way.
The good news is that the surrounds were installed so poorly they literally peeled right off and both were out in 20 min. However, the cones are still riding way low in the basket. The worse of the 2 has almost no resistance to being pushing downward and bottoms immediately. The other has better resistance and rides near to where it should, though still low.
What's wrong with these drivers? Are they paperweights? They both travel the full distance with no scrapes when centered, don't make any sort of bad noises. Will they "relax" in time and return to a centered position?
