Rebbi- The whole single driver speaker (7XRS in my case) presents a seamless transition of the instruments or voices. What I mean is that as a piece of music is playing, the ability to listen to as a whole, or to pick out individual instruments and follow their lines is easy. It is just right there in front of you. I never once in my listening to the 7's think that there is top end missing because there is no tweeter. I am adding an Omega sub (8'') that I should receive early next month. It's not that I feel the bass is missing, in fact it is the most complete sounding bass I have every heard in my home. The Peter Gabriel album ''Plays Live'' that I was listening to last weekend, and the song Humdrum has Tony Levin playing bass there are so many little fill in notes that he is playing as he move between the chords. It is so easy to hear every detail on a recording. I am adding the sub just to flesh out the very lowest notes of bass pedals (I still have my set of Moog Taurus pedals) so things like early Genesis, Yes, Rush have the low end grunt. I can sit and the music just washes over me. Lorenna McKinnet's Nights from the Alhambra album has so many different instruments playing different melodies and rhythm and you can hear everything, nothing is buried. The speed of the driver sounds faster than the electrostatics's I used to listen to. Soundstage is huge, and I have not experimented with placement yet. I just placed them where my old Sequerra's were, measured the distance off the back wall (back of the cabinet is 15'' off the wall) and have a very slight toe in. Side to side, height and depth is fantastic. Of course that is also based on the recording, but I have not played any recording and doubted my purchase of Omega's or Decware. Even Frankie Goes to Hollywood's 45 rpm of Relax just rocked the house last night. Listening to some cello music right now and it is eerie how life like it is. Does it sound like a 9' Steinway Grand piano in my living room? No, and I don't want a 9' grand in my living room but it sure sounds like a window into a space. Sorry for the ramble, and I am actually have a tough time expressing my thoughts on these other than totally happy. If you are wavering on making a purchase, I cannot speak higher about this product. I am happy, and amazed daily. Happy listening, Chris.
