    Okay, so I couldn't stop, and pulled the second 2425J to find the dampener pad pretty well disintegrated. Not as bad as the first one, but just as sticky. Still can't figure out how JBL can produce...

    All done, I have my living room back!

    Not a lot of adjustment in the 2122H surrounds. Luckily they fit perfectly. Thanks to Rick Cobb for another success. Ran the 30Hz tone just for the heck of it, with no issues. There's just not a lot...

    I used an old bottle I had around. It is 91% Isopropyl I've had it so long I think the price tag on it was something like 45˘! Can't really remember what I used the last time. Don't think it was...

    Pulled the first 2123/2122H today. Much easier than when I pulled the 2245. Had the heat-gun ready but didn't need it. Just slipped a thin putty knife underneath and it lifted right up. Removed the...

    Full-time maintenance on old stuff! Cars and speakers.

    So, I had a little time today. Too hot to mow and I'd already helped a co-worker move a couch from a city 70-miles away.

    Again, thanks for the advice and shared experiences. I plan on swapping left/right and, if it confirms my theory, take the faulty driver apart and document it here with pictures.

    Yeah, I'm aware of all that—which is why I'm asking the question about manufacturing quality of the Mexican parts and comparative sound quality of the Radians! The decision is no longer to select...
