Hello, I picked up a pair of JBL L112 speakers and the 128H’s needed new foam. I refoamed both of the 128H drivers using a 30hz tone generator on both and followed the same steps. I ended up using Simply Speakers surrounds and Aleene’s Tacky Glue. I didn’t hear any rubbing during the process, but after the glue dried I hear some distortion in one as I tested on very low volume, no bass. Also, when I push in various places on the cone to test, one half of the cone has some rubbing and makes a scratching type noise. Does this mean the voice coil on this driver is not centered? Could it be anything else? Thanks
