Hateraid is correct. Flat from 20 to 20k is the goal of any 2 channel speaker system. To get that level of SQ would cost far more than a Porsche and some components and subs. People spend 100,000.00 plus to achieve that goal. IMO if you want a system to sound the way YOU want it to sound, which in my case would be the "west coast" sound, that is one thing. A flat response with a width and depth of soundstage is another. It all comes down to what YOU want to hear. Give me some up front mids and some God **** overwhelming bass when I want it any day. That is my preference. Yours may be different.
