Right now, i think the dual 600's is the sweet spot... I dont have a mic or any computer software to read the room response, so you will have to take my "seat of the pants" readings... i can TOTALY tell that the room response has greatly smoothed out... MUCH fuller... earlier i listed to Metallica's master of puppets CD, this was almost as good as my old car stereo that had 3 10 W6's powered by a 1000W phoenix gold amp (90's U.S. made power), that would play to 146db... This setup is a heck of a LOT cleaner though.... I guess i would say this is like going from an inline 6cylinder BMW M3, or a 370z with its v6... To a C6 Z06 with a freaking Beast of a V8... All 3 cars are pretty fast, but one one can successfully argue against the raw power of the Z06....



You will have to bear with my car analogies, as this is the only type of context that i can put the experience in without using words like "amazing"/"warmer" and all the unquantifiable words that the reviewers like to use.....
