Thanks for straightening me out KW4Him on the bass thing . I guess it's just the design of the foam surrounds to eventually fall apart. I do think that everyone will have to replace the rear subs due to this issue. As for Tinnitus OneHundred80 I also have that problem from being a former musician "Kidneys" ? God knows i've run enough alcohol through them but life is good and my Crossfire makes it more enjoyable
