I was helping out on my Grand Prix forum and this guy was talking about the MTX 9500. He proceeded to tell everyone that they are far better than a W7 and have never had a negative warranty claim against them since they were introduced. I dont care about JL or MTX, but personally had a 9500 12 that had a bad voice coil. When it worked it sounded good, but I have read on here of other issues with them IIRC. I am just trying to get some background.
