Yesterday, I noticed one of my MA front speakers sounded a little different than usual, and found that the tweeter was silent. Since I had bought these babies last year at the now defunct Good Guys, my only recourse was to contact the North American distributer, Kevro. One e-mail to them, and Matt Armstrong, product manager, replied that a new tweeter was on its way. Wow!
Sheesh, nothing to complain about. Too bad all companies can't just do this.
