There is an incredible struggle going on in design work.
Design is about 1's and 0's, X's and O's--formulas.
Music is about emotion and feeling, (think Micarelli playing Emmanuelle with Botti or, you name the piece).
The two posters here, duking it out are a perfect example of the thoughts which tug at a designers heart (and to be truthful, purse strings).
At what point does my speaker sound 'flat and neutral', and then at what point does that (even 1/4db difference in output of the tweeter, give it an overly analytical sound, or, God forbid, 'bright and hashy'?
I personally went for this: "The best tweeter I ever heard, I didn't." Try to tuck the tweeter in right beneath the midrange--measures flat, but never, never calls attention to itself. Also, chose a tweeter that doesn't 'spike' in the last octave, (10Khz to 20Khz). At least the last octaves for most of us...(note: does not include your favorite Akita, or Corgi.)
The problem with this 'careful balance of loudspeakers is', that that damn 'free will' thing rears its ugly head.
One designer of a THIEL like sound is realizing that the customer NEEDS some electronic 'help' while another is thinking the exact same thing, but hoping for the opposite 'voicing' of electronics, say Vandersteen/THIEL.
I was wondering if this debate would develop and I'm glad it did.
Personally, I went for a 'really dynamic midrange', flat but not too forward high end...and think that that's what we hear 'live' in an accoustic venue.
The third, most important diminsion in audio is the listener, his/her preferences. Interesting.
Good listening.
