Out of the box the J&Ms weren't impressive, and I'm thinking, "This is what you get for $80, what did you expect?"
Since the magnet was bigger and the cone seemed better quality I did the install.
If you are a touch PTSD and can't stand much distortion they are well worth it.
If I did it again I'd custom fit a higher end pair, but for under one hundred they are worth the effort.
