Heya - I'm running a dual spectrum 800W cooltube, and the fan I am using is virtually silent (1.0 sones). I can't hear it running at all in the bloomroom, even with the door open, but the sound of the air moving, exiting the 6" duct exhaust is pretty loud. I am using the accordian like 6 "dryer hose" and have tried wrapping the duct with towels and such - no luck. I'm building a muffler now, but it is not as small as I'd like and I'm worried about decreasing the flow beacuase of restriction.

Anyone else ever have this problem and what did ya do to fix it?
