Yes thanks I understand the spec. Most here cover the lower mid and low bass with subs; whilst some believe the powered woofers in tower speakers can make up for not using a sub, their designs tend to be lacking. I originally intended my comment about the addition of powered woofers integrated into retail designs to highlight thats its not all rosy. I liking it to a buyer shopping for watts, electronics and not a speaker. There are a fair amount of 2/2.5 way speakers that have no problem hitting the peaks in most rooms
