Correct. Definitely helps avoid localization. I hate feeling people talk into my back. Had that problem when I had bass shakers back in the day...before I knew anything about DSP.

I wondered if having the directional bass behind you with the surrounds would work.
Spot on Luke.
I have done quite a bit of experimenting with my AVR crossover. Back when I had my dual LMS-U's I found the best arrangement was setting my front L/R (RF-7II's) to large to assist the LMS-U's (crossed around 70Hz using my old SMS-1) with mid-bass. Klipsch spec the RF-7II's at 30Hz-24KHz ± 3dB
and, while we all know the .1 channel is independent from the stereo bass the L/R speakers are subjected too, I felt strongly that employing the preverbal "double-bass" was much more enjoyable all around.
Speaking of that, is the term "double-bass" intended for strictly movie watching, or does any music employ LFE in addition to stereo bass? Or is the term a simple reference to utilizing your both your speakers AND your subs to play bass content? Not sure if I worded that correctly?
To address your other question, I normally keep my center and rear surrounds crossed at 80Hz regardless of my L/R setting. For movies I have to filter the rear subs. I'm practically sitting on top of them. I've played around and crossed the rear subs as high as 100Hz, but that didn’t last very long...just didn't like it. That said, I do have a "showoff" button on my Harmony that switches miniDSP curve of my rear boxes to match my front. Gives more mid-bass for music, but not as enjoyable (IMHO) for movies.
I'll play with it some more at some point when I can make time for it. Maybe set all speakers at large to see how my little 6.5" woofs handle the WOTW scene...lol
