sub crossover problems

[kylek100]

I have a Denon 3805, B&W 805S's and a Velodyne DD-12. I was just testing the frequency response using a tone generator in my computer, and I was starting to notice that my main speakers are attempting to play frequencies far below the crossover point. In other words, when I was playing 15 hz, the drivers of my B&W's were moving at a furious 15 hz trying to keep up with my sub. Shouldn't the crossover make it so all the stuff below 80hz goes to the sub and so on? I know there's a little bleed over to make the transition smooth but I wouldn't think stuff that low would fall inside of that. Anyone have suggestions?

By the way, the sub is just hooked up to the sub preout on the receiver and the front speakers are hooked up normally.

Are your main speakers set to 'small' and your sub/lfe set to 'sub' only?

Yup sounds like one of these settings must be off

Does everyone set their mains to "small"? How big would your speaker have to be before you set it to "large"?. If Kylek100 had is speaker setting on "large", how would that affect the sound. Also, what other option would he have on the sub setting besides setting it to "sub".
