I've had them up & running for about a week now & I must say they were well worth it. Now mind you the LSi/FX surrounds are superb in their own right but they weren't quite the perfect match for my new KEF setup. Having the main 5 speakers timbre matched makes all the difference in the world. Dan (mantis) has always stressed the importance of timbre matching as much as possible & he is correct. The music & movie action & voices are more coherent & dead on accurate, the audio just pans & flows as natural as can be. You are more emmersed in the action & music score, it makes for a more complete experience.
Now does anyone need a mint pair of LSi/FX speakers?
