For my room, yes. I tried all the combinations, even mixing settings so that one was in Low-HT and the other in Low-Music, I didn't mix LFE and Line-in, they are too different. I was searching for the fewest pre-eq peaks and, more importantly, nulls or valleys and found it using Line in, Low-HT, and 12Db on both.
I would cross your Paradigms at 80hz (try 60hz and 100hz as well), not so much for them but to separate the bass frequencies from the upper frequencies allowing you to place each in the 'best' location in your room. It's nearly guaranteed the best speaker placement for sound stage and imaging is NOT the best place for bass. Not to mention it relieves the heavy burden off the amp/receiver driving the Paradigms and leverages the custom spec'd amp made to drive the servo driver in that specific box.
Your space is a little bigger than mine, 16x13x8, but dual L12 really get the room pressurized with loads of headroom. I have two GIK bass traps in my front two corners as well to help kill a 50hz room peak and reduce decay time. I've only had the L12(s) setup for a couple weeks, and just dialed them in this past weekend. The few movies I've watched, I was quite impressed and found myself turning it down as this is the first time I've had a system that was able to reproduce all of the dynamic range without running out of steam, and others were in the house.
