I have the Energy C8 speakers. I use these for home Theater. They are definitely one of the best speakers for the money. They use 2 8 inch woofers and the tweeter. They also use a gorgeous black gloss cabinet. I think the 8 inch woofers are really good. They sound very articulate. The tweeter is the weakness. Its an alluminun tweeter. I would love to replace this tweeter and use a better tweeter. Ofcourse then you would have to change the crossover. Anyone have any idea's.
I would NOT fool around with trying to swap out tweeters.. I have tried this with some old 70's speakers with poor integration/timbre/voicing of the sound on the whole type results. Much better idea to audition different cables, cardas for example.
