Hey
Thanks for the info. I did call customer service, and all they were able to provide me is that yes it is a replacement through another vendor, however I couldn't find any specs. I think your right and replacing the bottom on both is a great idea.
I did check the caps, and the xover boards and air wound coils, the wiring isn't even tanned. I really wasn't driving them hard, and didn't notice any burning smell eminating. I used the parametric EQ to boost the 38 hz range up 6 db. The output meters were at about 50W on my MX1000. It added some more low bass drum punch to a few slower rock songs I was listening to sounded quite nice, but I suppose I added to much punch .
I want to remove the plastic piece around the front of the speaker - trying to remove it carefully but no luck so I could start removing the rubber surround and then the spider to inspect the voice coil. I'm not sure if all of them are this way, but this particular speaker seems to have a new front rubber surround and whoever glued the plastic surround back used some epoxy instead of the regular tacky glue.
Are these drivers pretty well built or are they really this fragile?
thanks,
Jonathan
