I just got this speaker today... http://www.futureshop.ca/catalog/pr...3&sku_id=0665000FS10008187&catid=&newdeptid=1 and I've been noticing some SHAAHAHAHAHAAASSHAASHAHA sound ... could it be that i turned it too high? or what? I'm just listening to 20th century plain music.. it sometimes happens. Heard it 3 times now, dunno why. I place my two satellites right beside my monitor (but they are magnetically shield) and the subwoofer on the ground. So what's wrong?
