I've noticed moderate problems with the CW too.  My audio is Prologic 
for this channel.

I set my low pass filter on my sub to, I think, 50hz a long time ago and 
left it alone.  The cross over point is a function of the frequency 
response of your mains vs your sub.  You should be able to figure out 
where you mains drop off and set you sub to that frequency.  Set it and 
forget it.

I recommend getting the AVIA home theater calibration disk and a sound 
meter from Radio Shack.  However, for setting the sub volume, I used the 
use the 5.0 and 0.1 white noise test tones to set the sub volume rather 
than the normal 1.0 and 0.1 test tones.  (This should make sense when 
you go to set your sub volume.)

Good luck
