Well the main reason that I bought the new rears is that they were on sale at a great price and my rears that I was running had a midbass driver that was starting to show signs of going bad when playing blue rays that have more intense rear channel information. You are right that the rears do not carry as much information as the other speakers but when playing blue rays with the better audio formats the rears are more predominant than when DVD was the main format and I can tell a huge difference since installing the new rears. The Center channel thing is something that I will address at some point but my 2 channel setup is my main concern as I have a new preamp on the way for 2 channel listening. That is my concern for my system is music but I could not resist the price of the surround speakers and new that they were going to improve the audio performance of the theater part of my system.
