Latest update. I tried both subs in both rooms this weekend, and tested a few Blu-Ray's. I also took Shady's advice and ran Audyssey, both ports open, and jacked up the sub calibration by a few dB. Big improvement from before. I became especially happy when I could hear the stuff on my walls rattling throughout the room. I think the sound quality of the subs are great, and when you throw two in the mix, it will definitely give you that boom effect you want out of a home theater.
The only downside is that I now have to split up my subs, and throw one in each room. I'll probably save up for another sub in six months or so, and then move them both upstairs and run the new one downstairs.
Altogether, I have nothing but nice things to say about the LFM-1 EX.
