I have my crossover point set at 60 Hz and all speakers set to small and subwoofer=yes. Just to verify that bass below 60 Hz wasn't being sent to my mains I used a CD that produces tone sweeps from 1 Hz up to 60 Hz on one of the tracks. The cones are definitely moving/producing sound after about 25 Hz. I'm using Paradigm Monitor 5's BTW. What can I do? The manual pretty much says nothing else on this other than what I'm doing. Is the crossover only valid for sources other than CD or only during digital movie playback?
