I have decided to buy either the Energy C5s or C7s. The C5s are said to be 2 1/2 way speakers, while the C7s are true three way speakers. What does that mean as far as sound quality is concerned? The C5s have 2 6.5 inch woofers while the C7s have 3 5.5 inch woofers, and the C7s go just a bit lower. Would the three way factor really mean a big improvement in sound? I imagine the C7s would image better, but with a 55 inch widescreen TV and audio rack in between, I don't think anything would image too well. The price difference is $250. Thanks.
