..just some extra thoughts. When using my headphones, the striking of a cymbal, the crack of a claves, etc is very fast...you can hear the strike, and then the sound. When using no Vandersteen rear tweeter...its as the headphones, but recessed...listen very carefully to hear it. When using the tweeter, the body of the stike is there, but the actual strike is "confused". I'm thinking that the phase is screwed up with that rear tweeter. My room is very big with 16 ft ceilings....I use the tweeter, but just barely. Its like sub woofers....if you hear it, its way too loud.
