I have a sunfire MarkII and have never heard any humming. It does pop when turning itself on or off but ill deal with that for the serious bass it pushes out.
Do all sunfire subs hum and pop?
I have a sunfire super junior that almost constantly hums and on occassion makes odd pop or ckicking sounds. I have witnessed anothere that had the same hum. Its sounds like the same hum that comes from my cieling fans or low voltage lighting. Obvious I suspect the power. I've tried the Monster HTS 5000. Didnt help. Before I spend more money I thought I'd put out some feelers. Any help would be appriciated. Everything else seems to be fine except a hum bar that runs from left too right only when watching DVD's. Sorry if this is a redundant topic. Thanks for any help.
