So, I have set up my old PC speakers in the kitchen, plugged in the Karma, sounds great !!!

All was fine until I unloaded the Dishwasher! There is very annoying resonance coming from the glass cupboard! The sub has to go on top of the units, near the ceiling, and this is making the bass a little boomy. Where else could I put a Sub in a kitchen, I tried ontop of the fridge and it sounded weird, there isn't anywhere else for it to fit. Dammit !!!

Cheers

Yeah, who'd'a thunk putting a subwoofer in the kitchen would be problematic?

Just stick it at the back of a cupboard. As Julf said, positioning shouldn't make a difference if the sub is any good. You could even put it under/behind a load of crap as long the vent (if there is one) isn't obscured, otherwise you'll get port turbulence.

Mmmm, tried that, sounds very boomy when under the sink/in a cupboard

It's only a cheapo Labtec PC 2.1 speaker set, so I shouldn't expect too much, but it sounded great on my desk. Maybe I need to mount the speakers at head height, but that it going to start looking pretty nasty, I was hoping for a nice hidden install.
