hi sifus,
I have a Z5500', recently the woofer burnt my first fuse (came with the woofer) and i have replaced it as specification

but still it burns every new fuses I inserted. Anyone know what is the exact problem? The speaker's warranty is dead and Logitech dont even bother me about when I email them.

Anyone have the exact problem before? If yes did you manage to fix it?
If yes, please let me know.

Many thanks!
