My sub crossover is set to its highest (140 Hz I think) with level turned way down. Surprised me that that appears to give me the most even LF response. I went back and reevaluated a couple times including twiddling with the phase switch. I haven't done any science or anything but with other settings, bass lines were ducking in and out as they went up and down the scale.

I'm guessing there's some weird phase response curve at the low end of these little B&W's. That's why I want to HP them. Spec says they're good to 65 Hz but also says distortion is <1% only down to 100 Hz. I'm thinking there's pure crap from 100 Hz on down.
You're right, if I did get the intergrated amp I would go that way. My first choice would be the Outlaw 2150, (because of the bass management). I found out too late they had it on sale for $499, instead of the usual $699,the sale ended 4/20. I saw the Cambrige for $300,used, which is a good price.That with the Behringer, which would give me more flexibility, with bass management,and still would be under $400. I don't care about the tuner, where I live, the reception is terrible, a lot of interference.

You're probably right about the bass setting too, (I really didn't spend much time using the sub without using the bass management of the reciever). It makes sense what you are saying, the 8 inch driver of the sub probably can handle the higher frequecies better than the 6.5 drivers(in my case anyway) can handle the lower frequencies. I think it's better to have a overlap in the frequency even if it's not pristine, rather than to have a hole in it. I agree with you too, that low frequency spec on most speakers can be taken with a grain of salt, without a distortion number to go with it. There may be bass there, but how tight is it?
