No shiite Sherlock. Xd is also optimized for low distortion, low spectral decay, good transient behavior, low cabinet effects and broad, coherent dispersion. The other really important things in sound. Your last sentence shows how incredibly uninformed you are with respect to the technology involved and what it does (as usual).
John doesn't understand this because he doesn't have the mathematical background to
understand the mathematics behind digital filters - but digital filters aren't "perfection";
there are design compromises to be made in the digital domain also.
Hey, you don't have the "audio background" to understand the acoustics behind speaker design, but it doesn't stop you from pretending
You don't have to understand the "math" to understand the effect. Tell an archer he doesn't understand the mathematics of what he does and he'll shoot you right in the middle of your pointy forehead.
The Xd may be flat in the frequency domain; but it DISTORTs in the conjugate domain; the
Actually, the word is CORRECTS. Wilsons distort in the temporal domain.
In a listening test, I noted significant temporal distortion of cymbal crashes,
Really? How do you "note" that which doesn't exist in science?
"Note" any UFOs lately?
However, I do believe that
human hearing is quite sensitive to temporal response - the time domain.
And I believe in the Giant Spaghetti Monster. Science actually says the opposite of what you "believe". Look it up. Besides, if it were true, that only plays to Xd's strengths.
As John Atkinson's measurements show; the filters in the Xd are "acausal" - they will produce
sound before they are supposed to. That leads to the Xd "messing up" the microdynamics of
transients; even though it gets the time-averaged frequency response right.
Perhaps, but they also largely cancel. However, by lowering the crossover slope you can lower that effect if you like, but apparently the NHT crew felt the performance was better at the slope. You pick your compromise.
However, the acausality, and poor microdynamics is the deal-breaker for me; as well as
its mediocre reproduction of guitar; which is the instrument I play.
Oh, PLEASE. Do you know how many guitar players come in my store and go "Holy SHITE!" when they hear Xd? Gimme a break.
If someone is contemplating buying an NHT Xd; listen to it extensively before buying.
Again, no shiit. People should do that with *every* speaker before buying. The problem for you is, the more people listen, the more they like. I've had people that didn't think they liked it at first but kept coming back over and over and fell in love. And I have people that call or write e-mails to thank me all the time for their Xds. You know, the ones they chose over conventional high-end.
