The Energy 5.1 component set are very well balanced. Comparing them to the Infinity Reference, the Infinity's are alot more brighter. And the price is the same as the Infinity Reference.Now the Energy 5 1/4" and the 6 1/2" are the same price as well if you have the room go for the 6 1/2" they have a bit more of a full sound and a little more bottom end.Either way the Energy's sound great.
