I am using two subs as well and am hoping for an SMS1 this Christmas. I don't understand the stereo sub issue. Not sure how you get a true stereo LFE signal from a source to begin with and what advantage there is in a stereo sub 80Hz frequency anway? I would think that what you would be attenpting to do with the SMS1 is reduce the LFE stereo affect (double bass?). In the end you want the listener to find it hard to determine where the LFE signal is coming from, starting out with two seperate LFE signals would seem to make that harder. I guess it would be more fun to dial in each sub seperatly, but the biggest LFE problem in my room is loose dry wall nails. :-)
