This system is always in upgrade mode when the money comes. Problem is as the upgrades come the next upgrade is so much more than the lost they come less often. This is my family room turned into a theater/2 channel. Room is 11x20 with 8 ft ceilings. The way the house was built was unique especialy seeing as it wasnt built for a theater in 1975. The structre is very rigid so it fits with a descent construction for a theater, its not on a slab. It runs on 3 dedicated 20A circuits. It is very balanced especaily for not having a door to shut off the entry way, and then having a door for outside access that NEVER gets used. My nickname growing up was deep. I took it to DeepHz indicating low frequency, hence the sub rated to 14hz. Cant hear it but sure can feel it! The sig III make up the rest being they produce a clean 20hz. Next upgrades will most likely be blu ray, 65" screen, and maybe a mac processor.Ill get more indivual pic up later
