Hi, I have never heard the ProCinema speakers but I have heard the MLT-1's. I bought them for my son and I tested them in my system and I can say they are very well designed and sounded quite good for a small setup. They should be fine for a smallish living room setting. Since it is a matched set the sub should integrate fairly well with the small midrange drivers in the satellites. As others will say, its always best to go with a bookshelf system over a small satellite setup. The pioneer Andrew Jackson designed combo apparently is highly regarded as well. The MLT-2 will do fine for a casual type listening and movie situation,just don't expect thx levels here. That's a pretty large room, I think you will be disappointed with what you are looking at.
